00:04sinkholes they can be sudden catastrophic and deadly open the door there was no floor there
00:12everything was gone swear I could hear him hollering for me Jeremy helping and the numbers
00:18are rising all over the world even in Britain man just said that sinkhole in the back garden
00:26you've got to leave got to evacuate you've got 15 minutes to pack a bag and go with holes hitting
00:30the headlines when they did finally get to the bottom of the hole it was 80 feet deep time and
00:36time again but some places suffer more sinkholes than others this is what it's like to live in a
00:48sinkhole hotspot you're actually seeing people's whole lives really floating on the surface can't
00:55help but feel for people that are going through that on the night of the 9th of November 2016 Ripon
01:19Fire Service's blue watch was called out to an emergency something was wrong on Magdalene's Road
01:29Doreen Ellis was one of the first to get a knock on the door we were in bed sleep and
01:37there was a big
01:38knocking knocking on the front door hi sorry to disturb you and we called out to a sinkhole around
01:43the back man just said that sinkhole in the back garden got to evacuate you've got 15 minutes to pack
01:48a bag and go this is the colossal damage of a sinkhole which swallowed up gardens on Magdalene's Road in
01:58Ripon late on Wednesday night the ground had opened up beneath four gardens the hole was 30 feet deep and
02:07big
02:07enough to swallow a tennis court Peter Lister and Julia Osler were away when the sinkhole struck so
02:15the first they knew about it was when they saw it on TV we came up to the property to
02:22find the police
02:23the fire brigade the road blocked off because the sinkhole was still still moving I was shocked it was
02:31bigger than I expected it to be four homes were perilously close to the edge of the sinkhole and
02:37no one knew how much closer the hole might get all the garden next door was a wildlife garden and
02:43she
02:43lost all of that one of the garages had fallen in several of the outhouses had fallen in the trees
02:50the
02:50bushes the fences all fell into it the woman that lived up there was very lucky to be alive sure
02:56she
02:56came out my back garden went down the step I put one foot down and then I realized that the
03:02steps
03:03were moving I turned around and grabbed hold of a pole pull myself back up and and went quickly back
03:12into the house I think she's the luckiest woman alive I've never known anyone come so close ten houses on
03:20Magdalene's Road were quickly evacuated but the hole was still growing after about the second the
03:27third day we started getting concentric rings which actually went all the way up to the corner there
03:35where they where the bin is there but started growing and growing as days went by and growing and
03:41growing with the crack spreading many residents feared the worst this was the kind of thing that normally see
03:49on television you can see gravel dirt and roots inside this perfectly symmetrical sinkhole happening
03:57in another part of the world stories of holes opening up in faraway places swallowing people cars and
04:05buildings the building was collapsing around us our room itself is over 100 feet underground now
04:14Rippon was in the news and for the second time in two years because in 2014 another hole had opened
04:22up just around the corner in Magdalene's close and that one split a house in two last night a 25
04:31foot
04:31sinkhole opened up under this home in North Yorkshire and there was no time to stand and watch it actually
04:37started coming away I could hear it coming away above my head it was just creaking and cracking and
04:43fumbling and the couple living here were lucky because this hole sank slowly giving them time to get
04:50out but when sinkholes collapse suddenly under houses the results can be deadly Florida is the sinkhole
05:01capital of the world and Sefner in Hillsborough County lies right in the middle of so-called sinkhole alley
05:09a place that's notorious for one of the most shocking sinkhole disasters of recent times
05:19February the 28th 2013 was an ordinary day in this quiet town near Tampa Jeremy Bush had just returned
05:27home from work when my room started eating and heard his loud loud noise sound like a train or a
05:35car
05:35something's hit the house the sound Jeremy had heard was the concrete floor of his brother's bedroom
05:45collapsing I ran towards my brother's room open the door and there was no floor there everything was gone
05:55Jeremy's wife Rachel and her aunt Janelle wicker were also in the house you heard him screaming help and
06:03we ran out down the hallway a sinkhole had swallowed everything in the room including 37 year-old
06:12to Jeff Bush
06:14all you could smell in the house was like fresh dirt everything was just like churning on top of it
06:20I'd jump in the hall swear I could hear him hollering for me Jeremy help me
06:26there was I was digging with my hands
06:31there wasn't nothing I can do
06:34as Jeremy tried to save his brother Rachel dialed 911
06:38I need an ambulance and the top but he's stuck underneath the house the house just fell through
06:44okay and what happened to the house
06:47the bedroom floor just collapsed and my brother-in-law is in there he's underneath the house
06:52the emergency services arrived within minutes but time was running out for Jeff with the hole expanding a police officer
07:00pulled Jeremy from the room
07:01as I'm getting out of all the holes collapsing
07:09there was nothing I could do
07:14the police and fire crews brought in specialist equipment to search for Jeff Bush and try to save him
07:21all the family could do now was watch and wait
07:40what happened to the house
07:42the bedroom floor just collapsed and my brother-in-law is in there he's underneath the house
07:48this 911 call was made moments after 37 year old Jeff Bush was swallowed by a sinkhole
07:55the hole had ripped open right underneath his bedroom
08:00in a final attempt to locate Jeff and pull him out the police sent in specialist equipment
08:07while Jeff's brother Jeremy watched on with his wife Rachel and her aunt Janelle
08:12the hole opened up and took their equipment down the camera and everything
08:16so then everything stopped because the hole was still growing
08:21nobody did anything
08:24no one really even tried to rescue my brother with me
08:48the memory of Jeff's death is hard to live with
08:52but they also live with the knowledge that things could have been even worse
08:57too much prior to this my daughter was in that room
09:02so it could have been all of us at one point and not just him
09:06yeah
09:13the house was later demolished along with two houses on either side
09:17now there is nothing but fenced off wasteland
09:21a wasteland that hides the sinkhole that swallowed Jeff Bush and buried him alive
09:27that is my brother's last resting place
09:29I came out here on his anniversary when it happened to come out on his birthday
09:35it's hard when I do it man
09:39I love you
09:41I wanted to know that I tried everything I could to get him out
09:45do everything I could
09:52Florida is full of holes
09:55with new ones appearing every week
09:57so in this part of the world a sinkhole expert is always busy
10:02David Willshaw
10:03David Willshaw is a British geologist living in Florida
10:05in the 13 years he's been here
10:07he's worked on more than a thousand sinkhole cases
10:11well if you want to see a great example of a sinkhole
10:15here in Florida
10:16the Devil's Millhopper Geologic State Park
10:19is a place to come
10:20because here we have a monster of a sinkhole
10:23it's 500 feet across 120 feet deep
10:30the Devil's Millhopper gets its name from the gruesome remains that can be found here
10:35because when this ancient sinkhole formed
10:37it filled with the fossils of strange beasts and creatures
10:42when early explorers came down here
10:45they found this millhopper shaped hole in the ground
10:48and at the bottom of it was a bunch of bones and teeth
10:52particularly sharks teeth
10:53we had a lot of sabre-toothed cats, mastodons
10:57things of that nature
10:57and those bones all washed down to the bottom here
11:00where the Devil had been doing his evil work
11:03and these are the remains of poor creatures that lived in the past
11:07and they were subjected to the Devil's torment
11:10this is kind of like the River Styx if you like
11:12the pond at the bottom which is always present
11:19the boulders at the bottom of Devil's Millhopper
11:21are made of limestone
11:22the rock that lies beneath the hole of Florida
11:26it's a hard rock but it dissolves in acidic rainwater
11:31over time, water flowing through the cracks
11:33eventually forms caverns underground
11:36and when a cavern can no longer bear the weight of the rock and soil above
11:40it collapses
11:41and forms a sinkhole
11:44this is not by any means the largest sinkhole in Florida
11:47there have been historically enormous sinkholes
11:49some of the very large lakes we see in Florida
11:51are extremely large, miles across almost
11:54you know, so they can vary in scale
11:57and the scale depends upon how big the hole in the rock is
12:00into which the soil can move
12:02if it's a big enough hole
12:04and it can take enough of the soil that sits above it
12:06then you're going to get a very large sinkhole
12:16Rippon in North Yorkshire
12:18has the same kind of rock problems as Florida
12:20so all around there are signs of sinkholes past
12:25if you look to the left you can see in the field there
12:27there's some depressions which
12:28when you look at the mapping
12:29relate to historic events
12:33Ian Spears is Harrogate Borough Council's emergency planner
12:37one of the first people on the scene for the sinkholes in 2016 and 2014
12:43coming up on the right
12:44we've got the entrance into the old auction mart
12:46and that's where the property was seated
12:49that had the issues in Magdalene's close in 2014
12:54that sinkhole formed beneath this house
12:56it was 36 feet wide and 50 feet long
12:59and it ripped the house apart as the occupiers fled
13:03that was just up here
13:04you can see now that the building was demolished
13:09and thankfully none of the other properties were affected
13:13but the chap had left his dog in the house when he'd come out
13:16so the big concern was whether it's safe to to get the dog out
13:20the residents had managed to escape
13:23but there was a problem
13:25blue watch manager Kenny Beck took the decision to go back inside
13:28and rescue the dog
13:29well as we went in you could see undulations in the ground
13:32cracks appearing in the ground
13:33and the greenhouse had started to fall in on itself
13:36so it was a quick dashing grab the dog quick dash out
13:39and then calling off the area and evacuate all the immediate vicinity
13:44today the land where the house once stood
13:46is part of a large field close to rip in city centre
13:50land that would normally be ripe for development
13:52but just one week before the house cracking sinkhole
13:55plans to build 75 new homes here were rejected
13:59for fear of what lies beneath
14:04geologist dr. Anthony Cooper
14:05is the leading expert on what lies beneath ripon
14:09he's been studying the area for 40 years
14:11and drawn up a detailed sinkhole map of the city
14:14those ones that are quite recent
14:17also have other ones near them
14:19that have occurred in the 70s and 80s
14:21so the area is pretty well riddled with sinkholes
14:24this part of Yorkshire is a sinkhole hotspot
14:27with the british geological survey rating it
14:29one of the uk's most susceptible areas for sinkholes
14:33these sinkholes a lot of them are in lines
14:35those lines relate to the pattern of caves
14:38that have formed under ripon
14:40and are continuing to get larger
14:42and subsequently collapse
14:44so what causes the caves under ripon
14:47and why do these caves create such dramatic sinkholes
14:49the answer is found on the banks of the river yore
14:55just like florida this part of yorkshire is built on rock
14:58that dissolves in acidic rainwater
15:00but while florida has limestone ripon has gypsum
15:04gypsum dissolves about a thousand times faster than limestone
15:09this has come off the gypsum cliff behind us
15:12and just been carried across by the river
15:13it shows the typical dissolution effects
15:16that you get of water flowing over a soluble rock
15:18if i put this rock in the river
15:21it would only last a matter of about three weeks
15:23before it dissolved away completely
15:28when that dissolving process happens underground
15:31it can create caverns
15:33and when a gypsum cavern collapses
15:35it can be sudden and shocking
15:38well we're just standing next to a sinkhole
15:41that occurred suddenly in 1939
15:43it's about 18 meters across and nine meters deep
15:46there was no trace of it here before
15:47and the gamekeeper who was in the wood at the time
15:50came out very fast when this suddenly appeared
15:52if this sort of collapse occurred under a house
15:55it would be catastrophic
15:59in magdalen's road
16:00the sinkhole of 2016 swallowed garages and sheds
16:03but stopped just short of the houses
16:06but now the residents had another ordeal to get through
16:10months of uncertainty
16:11until their gardens were repaired
16:13and their homes were safe to return to
16:15we could see from our windows
16:17exactly what was going on
16:19and how it progressed
16:20from putting in the initial concrete
16:22then putting in tons and tons and tons
16:24of normal concrete on top of it
16:26and then tons and tons and tons
16:28of rock went on top as well
16:31watching the work it seems so slow and laborious
16:34but they could only do so much at a time apparently
16:36they had to fill it then leave it
16:37settle it check it measure it
16:39and then come back and do it all over again
16:41four to six months it took them to get all that done
16:45the repair work also included sensors
16:47that monitor movement of the land below
16:50but now the residents need to know for certain
16:52that the ground all around is as solid as it looks
16:56whether it's good news or bad news
16:58we need to know
16:59we don't want it to happen in our own backyard again
17:01but obviously it is going to happen again in ripon
17:03because ripon's a sinkhole area
17:08ripon is a city with a history of sinkholes
17:11but it's by no means the only one
17:15after the rain and the floods
17:17it seems the latest curse of britain's wet weather
17:21is the sinkhole
17:22there have been six reported cases already this year
17:26and part of the central reservation gave way
17:28along the m2 last week
17:30more and more sinkholes have been appearing across the uk
17:33causing havoc and mayhem for homeowners and motorists all over the land
17:38in high wickham a car on a driveway was swallowed up and buried
17:42and hitting the headlines like never before
17:45our daughter zoe was in absolute hysterics
17:48having realized that her car had disappeared into a hole
17:51many of those holes appeared in the chalky land of the southeast of england
17:55with one of the biggest holes opening up in the hartfordshire town of hemel hemstead
18:03the hole was 35 feet wide and 20 feet deep
18:07a sudden and shocking development for local resident martin boater
18:12we were woken up at half past seven in the morning by a policeman
18:17um saying that we need to get ready we need to evacuate you very quickly
18:20it was right under the road and goes right under the house
18:24so it's clearly very dangerous at this moment in time
18:26he proceeded to tell us there's a sinkhole that's opened up at the end of our road
18:30and we need to evacuate you
18:31due to the fact that there's a possible gas leak and potential explosion
18:36it looked like a serial murder scene
18:38because you sort of had police officers putting up tape
18:41the sinkhole had taken out all the electrics
18:43the water the gas that stopped the supply to all their houses
18:46they then found another void
18:48there was thought that there could be a void under my house
18:51there were thoughts of void under the neighbor's house
18:53and all sorts of things started to sort of go through everyone's mind
18:57it was a nightmare scenario for everyone on the street
19:00with no power and no heating in the middle of february
19:03and with the hole sinking and the danger rising
19:06the police evacuated 48 households
19:11you've got the wife in tears and the kids in tears
19:14and you know all with all we want to do is just get into a bed
19:17Martin was told that the disruption to his family's life would last for about a week
19:22but that week of uncertainty turned into months
19:24and months of chaos
19:27in the space of nine months we had moved 11 times
19:31the building closest to the hole had to be demolished and rebuilt
19:34so when the Boto family returned to their house
19:37they faced another two years of disruption
19:41the experience didn't stop as we moved into the door
19:44there was still that bit afterwards
19:46where they was demolishing the house and rebuilding the house
19:49and the driveway in and out of the cul-de-sac was relayed
19:52and dug up and relayed and dug up and relayed
19:55when we moved back home
19:56my son he sort of had these pieces of tissue on the on the carpet
20:00and I said Carter what is what is that
20:02and he said no no I'm playing sinkholes daddy
20:05and that to me was a telling memory in terms of
20:08not many kids would sort of grow up wanting to play sinkholes
20:11you know
20:13with the sinkhole eventually filled in
20:15and the buildings and road repaired
20:17life in Oatridge Gardens is now back to normal
20:21but in 2017 just around the corner
20:24a second sinkhole opened up
20:26closing another Hemel Hempstead Road for months
20:32because with sinkholes lightning can strike twice in the same place
20:39two years after the Florida sinkhole that killed Jeff Bush
20:42the land here opened up a second time
20:45daylight revealed a painful reminder for neighbors
20:48the very same sinkhole that took the life of Jeffrey Bush
20:51in February 2013
20:53collapsed again
20:54it's been filled twice or three times
20:57with gravel already
20:58and it still looks like it's gone down more
21:03tragedies like the death of Jeff Bush
21:04are a shocking reminder to Floridians
21:07of the dangers that lurk beneath the surface here
21:15because sinkholes in Florida
21:16are a fact of life
21:18with hundreds opening up every year
21:23so what's it like to see a huge sinkhole rip through your neighborhood
21:27all of a sudden a little hole grows into a giant hole
21:30a home gets taken a second home gets taken
21:33then all of a sudden the back property is affected
21:35you know within a minute
21:36you're in the middle of a worldwide story
21:38and what happens
21:40when a double-decker bus
21:42meets a sinkhole
21:43it did fracture the gas main
21:45one spark would have done it
21:59on the third of March 1988
22:02bus driver Jim Peitling set off
22:04for what he thought would be
22:05another normal day in Norfolk
22:08in fact
22:08he was about to park Norwich
22:10smack bang in the middle
22:11of the sinkhole map of the world
22:14I was on a normal day's work
22:16and it turned into an extraordinary day's work
22:19really
22:20I was on my last run of the day
22:23I had let a ready Crete lorry
22:24go past me
22:26about 15 to 20 yards past the bus stop
22:29the bus stopped
22:35there was a terrible grating noise
22:38of metal against something
22:40and I didn't know what it was
22:43when I looked out of the back of the bus
22:45there was any road around the back wheels
22:48Jim got his passengers off
22:49as quickly as he could
22:51and it was just as well
22:57because the bus was sinking fast
23:00the bus was just about
23:02two to three feet off of the ground
23:04it was held in that position
23:06by a gas main
23:07but once the gas main fractured
23:09it suddenly finished up
23:11in the final position
23:13like that
23:17suddenly Norwich was headline news
23:20and all because a burst water main
23:22triggered the collapse
23:23of an old chalk tunnel
23:24beneath the road
23:25creating the sinkhole
23:26that was eating Jim's bus
23:29just heard there is quite a gas leak
23:31apparently
23:32yes and I would like to get away
23:33from the interview
23:34to be able to see
23:35what it's all about
23:36we were very very fortunate
23:38there wasn't an explosion
23:39and thank goodness
23:40you had no smoking signs
23:41on the bus
23:42oh absolutely
23:43one spark would have done it
23:44so it was we were very very fortunate
23:48luckily the bus didn't terminate here
23:50it was hoisted out
23:52repaired
23:53and Jim drove it
23:54many times afterwards
23:55City central please
23:5630 people
23:57thank you very much
23:58thank you very much
23:59and for a while
24:00he was the most popular man
24:01in Norwich
24:01at least among his workmates
24:05shortly after the bus
24:07went down the hole
24:08Cadbury's put an advert
24:09in the paper
24:10with the slogan
24:12nothing kills a hole
24:13like a double-decker
24:14and they did send
24:15some double-decker bars
24:17to all of the lads
24:18on the buses in Norwich
24:19so yeah
24:20everybody did get
24:21a double-decker bar
24:22out of it anyway
24:24even though the internet
24:25didn't exist back in 1988
24:27that picture of the bus
24:28in the sinkhole
24:29went viral
24:30that image is the thing
24:32that has actually
24:33sold the story
24:34I'm sure it has
24:34it went around the world
24:36whether my name went
24:37with it to everywhere
24:38I don't know
24:39but it certainly
24:40I'm certainly
24:41quite well known
24:41in Norwich
24:46a vehicle-munching sinkhole
24:48that did go viral
24:49on the internet
24:49was this one
24:50in Kentucky in 2014
24:53it didn't open up
24:54in a road
24:55it opened up
24:56in a museum
24:57and it didn't
24:58swallow a bus
24:59it swallowed
25:00eight classic
25:00Chevrolet Corvettes
25:09the hole destroyed
25:10around one million dollars
25:12worth of collectible cars
25:13but this nightmare
25:15at the museum
25:16took an unexpected turn
25:19the sinkhole
25:20was a big attraction
25:21the museum
25:22doubled its visitors
25:23as more and more people
25:24came to see the hole
25:25and the crazy car crash
25:27it had caused
25:30it was beyond anything
25:31I'd expected
25:32just the size
25:33and I guess
25:36the depth of it
25:37while many sinkholes
25:38are big enough
25:39to swallow cars
25:40sinkholes
25:41that can swallow a house
25:42or two are rare
25:43even in Florida
25:46but in 2017
25:48that's exactly
25:49what happened here
25:50back in so-called
25:51sinkhole alley
25:52at Lando Lakes
25:54Pasco County
25:55just north of Tampa
25:58there's a sinkhole
25:59right next to
26:00our neighbor's house
26:01and it's literally
26:02eating the house
26:03when the 9-1-1
26:05call came through
26:06Kevin Guthrie
26:07coordinated
26:08the emergency response
26:09to one of the biggest
26:10sinkholes
26:11this county had seen
26:12for decades
26:13on July the 14th
26:14at about 7.30
26:15in the morning
26:16we received a 9-1-1
26:17call saying
26:18that the ground
26:18was opening up
26:19at the residence
26:20there on Ocean Pine
26:21Strive
26:21with the groundwater
26:23level so high
26:24the hole quickly
26:25filled with water
26:27local resident
26:28Terence Dewan
26:29watched his neighbor's
26:30houses crumble into it
26:31it grew like this
26:33and then
26:34it started doing this
26:37the ground started
26:38dropping like piano
26:39keys
26:40within about an hour
26:41what started out
26:42as about a 10-foot
26:43sinkhole
26:44ended up opening up
26:45to almost 150 feet
26:47and it moved over
26:48to that side of the
26:49house
26:49you know at that
26:50point you knew that
26:51they were in danger
26:58the first home was
27:00completely engulfed
27:01into the sinkhole
27:01within a matter of
27:02about 25-30 minutes
27:04and then it moved
27:05this way
27:05and you knew that
27:07that house was
27:08going to be in danger
27:09the second home
27:10about 40% of it
27:13was engulfed in the
27:14same time frame
27:15eventually
27:17engulfing probably
27:1860-70%
27:19within two hours
27:20and then once it had
27:22moved side to side
27:23then it started moving
27:24forward towards us
27:25that's when my blood
27:26pressure started to rise
27:29on the other side of the
27:30sinkhole
27:31Ralph Hartwig's family
27:33home was getting closer
27:34and closer to the edge
27:36two police cars parked
27:37in my cul-de-sac
27:38they pounded on my door
27:39and told me that I had
27:41to leave
27:42I watched the second half
27:44of the second house
27:45fall into the sinkhole
27:46over the deputy's
27:47shoulder
27:48so they didn't have to
27:49ask me twice
27:50once our mailbox went
27:52then we knew that
27:53we were in a hot
27:54hot spot
27:55you know
27:56by the time it finally
27:57come to rest
27:58about five o'clock
27:59in the afternoon
27:59ended up being almost
28:00250 feet wide
28:02by about 50 feet deep
28:09Ocean Pines Drive
28:10was now ground zero
28:12for Florida's
28:13latest sinkhole
28:14disaster
28:15and yet just a few
28:17hours earlier
28:17it had been a
28:18neighborhood that
28:19made the Florida dream
28:22the same dream
28:23that brought
28:23British geologist
28:24David Wilshaw
28:25to live in the
28:26Sunshine State
28:27even though he knows
28:28more than most
28:28about the dangers
28:29of sinkholes
28:32as we come round
28:33the side of this
28:34property you'll see
28:35why they built this
28:36neighborhood the way
28:37they did
28:37you got your boat dock
28:39you can take your boat
28:40out you can canoe
28:41there are some bigger
28:42lakes around here
28:42you can water ski on
28:43that is the typical
28:44Florida lifestyle
28:45everybody dreams of
28:46but it comes at a price
28:49for the residents here
28:50this dream had become
28:51a nightmare
28:53the sinkhole had
28:54swallowed two houses
28:55completely
28:56and nine more were
28:57left teetering on the
28:58edge
28:59condemned and earmarked
29:01for destruction with a
29:02red tag
29:04looks like a construction
29:05site which it has been
29:06for the last month or so
29:08the first thing they had
29:09to do was remove the material
29:11which was in the hole
29:12so there was parts of houses
29:15a couple of boats and there
29:17were septic tanks
29:19so to avoid polluting the
29:21local lake they've been
29:23pounded the area where the
29:24sinkhole occurred basically
29:26they filled it in with
29:27crushed limestone and then
29:28built a dam around the edge
29:30of the the sinkhole lake
29:31which is now formed
29:34for Terence Dewan the filling
29:36and work didn't save his
29:37home the property has been
29:39condemned as too dangerous
29:40to live in
29:41be careful you can see this is
29:43the concrete line where the
29:45where the hole was on the
29:46driveway because this this was
29:48my driveway that went out you
29:49know 40 feet and that's it's
29:52in the hole I mean it stinks
29:53through no fault of your own
29:56you know your property is pretty
29:57much not livable and at the end
29:59of the day we're not going to be
30:00living here again back in
30:04Ripon it's nine months since
30:06the sinkhole that swallowed
30:07four gardens and local
30:09residents are now putting
30:10their lives back together
30:13Peter Osler and Julia Lister
30:15bought their house here as an
30:17investment to do up and sell
30:18and give them both a pension
30:21so a sudden sinkhole definitely
30:23wasn't part of the plan
30:25this was just a little cupboard
30:26here which we then made into
30:30an ensuite we've totally
30:33rewired it we've totally
30:35re-plumbed it we've re-insulated
30:38it all we haven't shirked on
30:41on anything with so much time
30:45and money tied up inside the
30:46house the need to know that
30:47this part of Ripon is back on
30:49solid ground when the sinkhole
30:54swallowed the gardens here
30:55Harrogate Borough Council called
30:57in the British Geological Survey
30:58X-ray straight away their
31:00measurements of the size and
31:01depth of the sinkhole were
31:03crucial to working out how to
31:04fill the voids below and
31:06stabilize the land above now
31:10Dr. Oliver Kouris and his team
31:11are back to take a form of
31:13geological X-ray of what lies
31:15beneath so what we're doing here
31:17today is we're running a
31:19microgravity survey and that
31:21involves using a gravimeter we're
31:23essentially taking images of the
31:25subsurface much like a medical
31:28doctor would take images of a
31:30patient's body to try and
31:31understand what's going on inside
31:34To ensure that a sinkhole doesn't
31:36strike twice it's vital to fill all
31:39the open spaces beneath in Sefna the
31:42hole that killed Geoff Bush was
31:44filled with gravel and all of it
31:46disappeared just two years later but
31:49filling holes is expensive so in
31:52Florida many are left to become
31:53lakes and in Ripon historic sinkholes
31:57have become landmarks especially the
32:001834 sinkhole that may have
32:02inspired one of the world's best
32:03loved children's books Alice in
32:08Wonderland is the story of a girl
32:10falling into a rabbit hole and
32:12entering a magical world
32:13underground the man who wrote it
32:16was Lewis Carroll a regular visitor to
32:19Ripon because his father was a
32:21clergyman of the cathedral when you
32:24combine the quirkiness of Ripon
32:26Cathedral with the drama of the
32:27city's sinkholes you have the
32:29makings of a fantastic story so did
32:33Alice fall down a rabbit hole or a
32:35sinkhole geologist Anthony Cooper
32:39claims the answer lies right here
32:40behind this clump of trees when you
32:43get a bit closer you find to your
32:46surprise that there is in fact a 20
32:50meter drop down a down a hole with
32:53red sandstone exposed in the back of
32:55it there it's about 11 meters across
32:58it's about 20 meters deep this hole is
33:01close to the city's old railway
33:02station so Lewis Carroll would have
33:05passed it many times I think there's a
33:07strong connection between Alice going
33:10down down down not a rabbit hole but a
33:12sinkhole but you can't say in a
33:15children's book Alice went down a sinkhole
33:17and they probably didn't even have a name
33:19for it then
33:23Lewis Carroll isn't the only person to
33:25take inspiration from Ripon's sinkholes
33:28just across the river at Ripon golf club sinkholes
33:32are a feature of the course they call them
33:34bomb holes here and according to club member
33:37Anthony Blackburn the players love them because
33:40they're an ever-changing challenge the
33:42area that has got the sort of a shrubbery in
33:45it that is one of the biggest sinkholes on
33:47the course that one it looks pretty flat
33:50here but then all of a sudden just over the
33:52brow of the hill you've got this huge
33:54bump hole which just appears you've really
33:56got to carry this with your drive if you're
33:59gonna get a chance to either make birdie or
34:00power in this hole every one of the first
34:04nine holes here is peppered with sinkhole
34:06craters and land that seems to dip a little
34:08more with each passing season as we come
34:12further up the fourth fairway you can see
34:14quite a significant indentation here on
34:17the left-hand side this has gone from being
34:19a completely flat green to one that I
34:22suppose slopes quite severely from back
34:25to front it slopes so much that during
34:28the summer months in particular the green
34:30staff cannot put the pin anywhere near
34:32the middle or front of the green because
34:34it's so fast and downhill that the ball
34:37just keeps on rolling off the green and
34:39it's virtually impossible to stop it
34:40although on the plus side get your shot
34:43wrong and there's a good chance you'll
34:45get a sinkhole in one one of the things
34:47that really amazes me when I play with
34:49visitors is they come to places like this
34:51and they go wow look at that I didn't
34:54know that was there isn't that amazing
34:56and it's interesting that they love the
34:58quirkiness of this front nine holes of
35:00golf and often it is because of the
35:02features from the the gypsum sinkholes
35:04really the missing of that put had
35:07nothing to do with the gypsum perhaps
35:13it's no coincidence that Florida has
35:15more sinkholes and more golf courses than
35:18any other US state most of the water
35:22features and lakes here are sinkholes
35:25including the one in lander lakes pasco
35:28county that struck so shockingly in 2017
35:33the property is condemned if you feel the
35:36ground shake I'd start running
35:39ralph hartwig his wife and baby's son as the
35:43hole swallowed the house usually it would
35:46be mowed this was where you hope your
35:50son would grow up and play and yeah this
35:54would be where my son would play what
35:56do you think will happen to this house
35:57now county's probably going to knock it
35:59down and make a park out of it who knows
36:03all ralph can do now is think about
36:05everything the sinkhole has taken from
36:07him how do you feel to be standing in the
36:10garden here looking at you you would have
36:16to censor that on the other side of the
36:25newly formed lake Terence doing is
36:28stepping back into his condemned home for
36:29one last look around all right so where
36:35where we at right now obviously we're in
36:37the kitchen we've removed all of our
36:39things this was the nice granite and new
36:43counters and and cabinets that we had
36:46put in we had all new appliances that we
36:48bought if you're not careful you'll trip
36:51over some of those right there normally
36:54that water would have drained off and
36:56instead you know seems to be pitching
37:00inward and you can kind of see the the
37:03water signs there we got a boat we live
37:07on a lake it was one of those things
37:08waited a couple years save up some money
37:10get the boat live on the lake have fun
37:12and then it's just kind of gone one of
37:17the cruelest things about a sinkhole is
37:19the speed at which you can take so much
37:21away all your hopes dreams and plans sunk
37:25in a matter of moments usually it happens
37:29on TV and it's it's somewhere else you
37:31know and you're watching other people
37:33deal with the tragedies and and the
37:36things that you know that that go on
37:39when when holes like this open up of
37:41course this hole is a little bit
37:42different you don't see holes like this
37:44opening up every day you don't see a
37:46big hole open up and and basically
37:48swallow two homes back on the other side
37:52of Ocean Pines Drive Rolf may have lost
37:55his home but he's staying positive he
37:58believes despite everything he's a lucky
38:00man now when I tell you that I'm a
38:02fortunate individual that's why his
38:09wife Sule and son Henry got safely out
38:11of the house so you may be looking for a
38:16new home but you're both safe and your
38:17son is safe too yeah we're very lucky
38:21aren't we
38:27so can anything be done to prevent
38:30devastating sinkholes like this this
38:33probably the most documented sinkhole in
38:35history and what lessons can sinkholes
38:38teach us buildings have to be designed to
38:40a higher level of safety to allow for a
38:43future sinkhole collapse
38:57I asked everybody out there please pray
38:59for the people in this community right
39:00now they're fearful and unfortunately we
39:03can't give clear answers because this is
39:04mother nature when the lander Lake sinkhole
39:07made the news all over the world in 2017
39:10one expert realized it was happening
39:12very close to home because I grew up
39:15right near here I was very interested
39:18right away and and understanding right
39:20away where they were talking about
39:22dr. Laurie Collins the geoscience
39:25professor from the nearby University of
39:27South Florida so this was a perfect
39:30opportunity to study a sinkhole from
39:31beginning to end using the sinkhole
39:37the same kind of technology that the
39:38British geological survey have been
39:40using in Ripon dr. Collins and her team
39:42assembled a 3d picture of the surface
39:45here and what lies beneath this probably
39:48the most documented sinkhole in history
39:50we're going to be making all of these
39:52data sets freely available so that we
39:54can really see understand and share the
39:57science related to this site their
40:00research shows that this entire area
40:02used to be a lake and that lake was an
40:04ancient sinkhole by sharing this
40:08information with experts like David
40:10Wilshaw dr. Collins hopes that
40:12disasters like this can be avoided with
40:15a much better understanding of how and
40:17where to build houses in the future
40:20well this is great to have an actual
40:21kind of 3d image of a sinkhole with
40:23that is something we rarely get what we
40:26have been able to show is that there's
40:28been dredging of the Lake Saxon area
40:30that essentially took all the dredge
40:33material and made new land so most of
40:36what we're seeing through here is that
40:38are actually houses sitting on new land
40:40or changed land surface
40:45the problem for Florida is that its
40:48population is growing all the time and
40:51properties are being built on new land
40:52all over the state that's why sinkhole
40:56reports are rising year on year because
40:59more and more people are living right
41:00on top of them
41:05Jeremy Bush and his family are still
41:07struggling to make sense of a sinkhole
41:08collapsing right under their house
41:12swallowing and killing Jeff Bush
41:16with their house destroyed Jeremy and
41:18Rachel now live in a mobile home
41:20their lives changed forever by a sinkhole
41:26life's different going from living
41:29into a house living into a trailer I
41:32still have worries here because I got
41:34worried about the tree above my trailer
41:35now there's always something it's
41:38always something no one ever said life
41:40was easy back in Ripon the latest plan
41:45for the land where the 2014 sinkhole
41:48happened is to put caravans here
41:50instead of houses but Ross Nicholson is a
41:54geotechnical engineer who's been
41:56studying this land in detail and
41:58believes even caravans could be unsafe
42:00here if you can imagine a situation
42:03where perhaps in late January during the
42:06night in a heavy downpour or heavy
42:08snowfall one of the caravans subsides
42:11into a large hole of five meters depth
42:13with elderly people inside it how are
42:15they going to escape and as for
42:17building new houses in Ripon Ross says
42:20lessons should be learned from the
42:21sinkholes here and in other sinkhole
42:23hotspots all over the world so even
42:26if there are no sinkhole features
42:28present now they could appear in 40 or
42:3260 years and change the safety of a
42:34site completely so buildings are built
42:37on gypsum prone areas of of ripon
42:40have to be designed to a higher level
42:43of safety if I was a family man with a
42:46young family living in Ripon I would
42:48like to know what's beneath my feet but
42:51I can also understand why people would
42:54prefer not to know back in Magdalen's
42:58Road Peter Osler and Julia Lister know a
43:01lot more about what's beneath their feet
43:03than they did before the sinkhole in
43:042016 the main worry was the unknown and
43:09as time has gone on you know the
43:12geological guys have come along you
43:15know and explain things to us so it's
43:20not frightening anymore the British
43:23geological survey will continue to
43:25monitor the land here to assess any
43:27remaining risk but there's no sign of
43:29imminent subsidence or cracking and the
43:32concrete plug that filled the hole appears
43:34to be doing exactly what it's designed to
43:36do on top of that most residents think
43:40the area looks better than it did before
43:42the sinkhole what you see today is
43:45absolutely fantastic it's bright in the
43:47whole area we've got a brand new road
43:50surface out of it as well we're the
43:52ones that letting the side down at the
43:54moment because we're still renovating
43:56so sorry neighbors Doreen Ellis too is
44:02confident that her sinkhole misadventure
44:04is over and that her house and garden are
44:06now firmly on solid ground we're
44:10apparently 99% sure you don't get two in
44:12the same place we know that other parts
44:15are ripping it could happen there but
44:18once you've had one you're not going to
44:19get another one so it's probably the safest
44:20place to live on top of a sinkhole
44:25and sinkholes returns with sucked under
