00:00 More than 100 aftershocks have been reported by PHIVOLCS, followed by a strong magnitude 6.8 earthquake that hit Mindanao on Friday.
00:08 PHIVOLCS explained that it could last for a few more days or weeks, but as it lasted, the earthquakes became weaker.
00:17 PHIVOLCS said that the earthquake was caused by the movement of the Cotabato Trench, because the earthquake hit the ground.
00:28 Liquefaction is the reason why there are fissures, particularly in the Padidog Gland in Sarangani.
00:35 Liquefaction usually happens in sandy areas near rivers and coastlines.
00:41 Because of the strong ground shaking, usually sustained for 30 seconds or more, sand particles will settle down and the water rises.
