00:01It's a Sunday morning in Colombia.
00:03A taxi driver to Cali sees the city and suddenly,
00:06he sees the buildings start to evaporate.
00:10An enormous rainstorms in the air.
00:13For a moment,
00:14it looks like the ground itself has exploded.
00:18He doesn't let it yet,
00:19but he sees the most powerful disaster
00:21that has been known in Colombia for decades.
00:24We talk about a earthquake of magnitude 7.4
00:28which struck the west of Colombia in August 2026.
00:32It took the life to more than 300 people
00:34and destroyed thousands of buildings.
00:38Today, a new study reveals why this disaster was so devastating
00:42and why the same problem could happen elsewhere in the world.
00:47At the time, Cali has suffered the most violent effects.
00:51It's one of the biggest cities of Colombia
00:53with more 2,2 millions of inhabitants.
00:56The cities like Manizales and Perea
00:59have also been deeply touched.
01:02But the disaster started in fact
01:04at about 5 hours of route
01:06in a small town called San Jose del Palmar.
01:10About 4800 people live here
01:13and this day,
01:14they have traveled something terrifying.
01:16More than 580 houses have been damage
01:19and electricity has been cut in all the area.
01:22The community has been completely isolated
01:25from the exterior world
01:26and the aid has been bad at it.
01:28It's a very mountainous region
01:30of Colombia
01:31and the main road of the village
01:33is not goudronnée.
01:35The cliffs of terrain
01:36were blocked after the disaster,
01:38so that the first secours
01:39by the terrestrial
01:40were only a few days later.
01:43Some rural areas
01:45were still without electricity
01:46a week after the disaster.
01:48Unfortunately,
01:50no one has been badly affected.
01:51But some inhabitants
01:52have said
01:53that it looked like
01:54the end of the world.
01:56In the streets,
01:57people faced
01:58the roof,
01:59the roof roof,
01:59the roof roof
01:59and the canalizations
02:01broken.
02:02But the real pressure
02:04went deep
02:04down,
02:05down,
02:07It's true
02:08that this part
02:09of the Colombian
02:10is located along the
02:11ceiling of the Pacific Pacific
02:13a huge area
02:14around the Pacific Pacific
02:16where the disasters are very frequent.
02:18The scientists
02:19still don't know
02:20exactly what effect
02:21caused this disaster.
02:23But they know
02:24that it was produced
02:25along a
02:25caused by
02:26in general,
02:28two enormous pieces
02:29of the land
02:30of the terrestrial
02:30have suddenly fallen
02:31one against the other
02:32later,
02:34instead of moving
02:35from high to low.
02:38Localizing precisely
02:39this rupture
02:40is difficult
02:40because this
02:41was incredibly
02:43deep
02:43at about 107 km
02:46below the surface.
02:47And that's
02:48something important
02:49to scientists.
02:50The rupture
02:51is not produced
02:52directly
02:53to the border
02:53between the NASCA
02:55and the South American
02:56is produced
02:57in deep
02:58inside the
03:00plate
03:00of the NASCA.
03:01At this point,
03:03the plate
03:03had already been
03:04pushed down
03:04to the South America.
03:06The pressure
03:07has stopped
03:08and then
03:09BOOM!
03:10The roaster
03:10has ceded.
03:12In summary,
03:14a deep fracture
03:14in the
03:15plate
03:15of the NASCA
03:16has suddenly
03:17released
03:18two
03:19blocks
03:20terrestrial
03:21the one
03:22against the other
03:23of the sea.
03:26The problem,
03:27it's that the sea
03:28profond
03:29function a little
03:30differently.
03:31As they start
03:31very far
03:32far,
03:33the secouss
03:33can spread
03:34into a massive
03:35zone.
03:36In the meantime,
03:38a part of this energy
03:39has reduced
03:39to reach the surface.
03:41But the problem,
03:42it's the place
03:43where it started.
03:45The sea
03:45has hit
03:46under the region
03:47of Tioco,
03:48one of the most
03:49poor
03:49of the Columbia,
03:50surrounded by
03:50a heavy jungle
03:52and at some
03:53places,
03:54the land itself
03:55has amplified
03:56the secousses.
03:57The walls
03:58and the deep
03:59walls
04:00can intensify
04:01the vibrations.
04:03Then,
04:03the secousses
04:04have reached the
04:04big cities.
04:05For many,
04:07it seemed to happen
04:07by waves.
04:08At the beginning,
04:09it was a brief secousses.
04:12Many inhabitants
04:13have thought
04:14that a big truck
04:14was next.
04:16But then,
04:17the telephones
04:18had to vibrate
04:19with an alert
04:20announcing
04:20that another
04:21could hit
04:22in the 20 minutes.
04:23One big one.
04:26It must be
04:27to say that
04:28these alerts
04:28do not
04:29predicts
04:29what they did.
04:30They did
04:31detect the first
04:33and the most weak
04:34and send an alert
04:36before
04:36the most strong
04:38hit.
04:39And when
04:40the violent
04:40hit hit
04:41this day,
04:42the damage
04:43had been terrible.
04:44The force
04:45was incredible.
04:46At a moment,
04:47the current
04:48had been cut.
04:49Some have seen
04:50that
04:50in the surface
04:51on the mur
04:52with the paint
04:53and the
04:53paint
04:53platter
04:54they had seen
04:55the secousses.
04:57And by their windows,
05:00they saw the buildings
05:01oscillate
05:02from one side
05:02to the other.
05:03But believe me,
05:05they had a chance.
05:06D'autres
05:07have experienced
05:07something worse.
05:09The
05:10videos of this day
05:11show the whole
05:12buildings
05:13evaporate.
05:14The enormous
05:15clouds
05:16envahi
05:16and people
05:18running out
05:18to find a
05:19place.
05:21And in the days
05:22that followed,
05:23the damage
05:24were everywhere.
05:25The schools
05:26were suspended
05:27in schools
05:27and universities.
05:29And five
05:30airports
05:31in Colombia
05:31were closed after
05:32the crisis.
05:34The secousses
05:36were also made
05:36feel beyond
05:37the region
05:38of Chioco.
05:39We saw them
05:40in the parts
05:40of the Valley
05:41del Cauca,
05:42the Risaralda,
05:44the Antioquia
05:45and the Tolima.
05:46Hundreds of thousands
05:47of thousands
05:48have been touched
05:49and 743
05:50buildings
05:50were flooded.
05:52It's difficult
05:53to represent
05:54such an
05:55amount of destruction.
05:57A recent study
05:58helps
05:59understand
05:59why
06:00the damage
06:00of the Americas
06:00have been so serious.
06:01Because yes,
06:03a magnitude
06:04of 7.4
06:06is extremely
06:07powerful.
06:08But the
06:09only number
06:09doesn't tell
06:10how much
06:11a tsunami
06:11will be destructive.
06:14In countries
06:15such as
06:16Mexico
06:16or Turkey
06:17are not
06:19very rare.
06:21The same
06:22for Japan.
06:23In April
06:242026,
06:26a tsunami
06:26of 7.4
06:28hit
06:28the
06:28large
06:29of the
06:29Sandriku
06:30on
06:31Honshu
06:31to
06:34Tohoku
06:34and Hokkaido.
06:36But the
06:37damage
06:37there was nothing
06:38to do with what
06:39we saw in Colombia.
06:40Only
06:40230 structures
06:42have been
06:42damaged.
06:44The researchers
06:45wanted to know
06:47why
06:47the damage
06:48in Colombia
06:48were more
06:49serious.
06:50And
06:51one
06:51part
06:51of the
06:52part
06:52of
06:52of
07:19the
07:20of
07:20the
07:20of
07:21the
07:21the
07:21of
07:21the
07:21of
07:21the
07:22of
07:49the
07:50in
07:50in the
07:50least.
07:51The
07:52the
07:53the
08:03the
08:04of
08:04the
08:05three
08:08of
08:09the
08:09that
08:09the
08:14of
08:18the
08:19small fissures, only big fissures could appear.
08:23It concentrates all the contraintes in one point.
08:27The inside of the wall casts and the wall cede.
08:31The researchers have also discovered another problem.
08:35The walls were so fins that even in adding more steel,
08:38it could not suffice. Their tests show that these walls
08:42simply don't have the necessary resistance to face
08:45and the most important thing is that this type of construction
08:50is also used in other regions of Latin America.
08:54The experts fear that the same tragedy can be reproduced ailleurs.
08:58And remember, six weeks ago,
09:01two powerful explosions had hit the Venezuela,
09:05almost 50,000 buildings according to the estimation.
09:10And as in Colombia, the ancient buildings were not ready
09:13for such violent secourses,
09:16what has aggravated the destruction.
09:20After two major explosions so close,
09:23the countries of South America have begun to examine
09:26the prevention of close close.
09:29There are more strict standards
09:30and a better planification of emergency.
09:33The hope is that during the next big crash,
09:36these buildings,
09:37these buildings more solid and clear evacuation plans
09:40allow them to save more lives.
09:43This is the end of the day.
09:44The end of the day.
09:45The end of the day.
09:46The end of the day.
09:46Bye!話

09:46You
