00:06 Good evening, Kapuso!
00:08 I am your brother Kim, who will give you the trivia behind the trending news.
00:12 Think about it, some residents in a town in Aklan are the ones who are the most arrogant,
00:17 who show off their place during low time.
00:19 What are these people?
00:21 Here in Tabon Island, in the town of Batan in Aklan,
00:29 we found out that JR was caught by a fisherman.
00:31 Maybe he just wants a mini chocolate hill by the sea.
00:33 During low tide, he can see a lot of things.
00:36 The top of it is 20 inches, we call it "bukid-bukid".
00:40 It's like a volcano.
00:42 Only a few things come out, and water.
00:44 And JR is one of those who noticed these things.
00:46 As time goes by, it increases and grows until its size.
00:49 What did JR see during low tide on their island?
00:53 Brother Kim, why is there a high tide and low tide?
00:58 The tide is the natural rise and fall of the ocean or sea level.
01:01 When it's high, it's called high tide, and when it's low, it's called low tide.
01:05 There are many reasons why the water rises and falls in our sea.
01:09 The main reason is the gravitational pull of the moon and the sun in our earth.
01:13 According to the expert, the "burol" that JR filmed are sun boils or sun volcanoes.
01:18 Even though the sun volcanoes are shaped like volcanoes,
01:20 because its cone and crater are shaped like a cone,
01:23 these are not volcanoes.
01:24 These are natural landforms.
01:27 These are volcanoes because of its conical shape or morphology.
01:29 And these are called sun boils because of the way the materials come out
01:33 from the vent or hole where the water with sand bubbles.
01:38 What are sun boils?
01:40 Because of the variation of pressure between the water-saturated sand layer at the bottom and the surface sand layer.
01:47 Because of the compaction at the top and the upward pressure at the bottom,
01:52 the water with sand ejects or releases from the surface is forced.
01:56 These are often observed in sandy areas near bodies of water.
02:00 But it can also be a manifestation of liquefaction in the area caused by the earthquake.
02:05 It's not dangerous, but it can affect the structures within the vicinity.
02:10 And it's much better if there's a field inspection by the concerned government agencies
02:14 to identify the associated geohazards.
02:17 But did you know that one of the biggest sun boils in the world
02:21 is the result of one of the strongest earthquakes that hit America?
02:25 This is the New Madrid Earthquake from 1811 to 1812.
02:29 This sun boil was found in Missouri, with a width of 1.4 miles.
02:35 Meanwhile, to know the latest news, tweet or comment #KuyaKimAnoNa.
02:41 Always remember, "Kuya Kim, Ano Na?"
02:44 Until we see each other again.
