00:00 Following the earthquakes in Mindanao and Luzon, PHIVOX clarified that it has nothing to do with the earthquake that hit the city of Pinagandaang and was expected to be the big one.
00:10 The whole detail is in the writing of Rod Laguzat.
00:12 These past days and weeks, the strong earthquakes that we are feeling are almost one after the other.
00:20 Here in Metro Manila, this is the only time that we have felt an earthquake from the Manila Trench.
00:26 According to PHIVOX, it has nothing to do with the Pinagandaang and West Valley Fault or the possible big one.
00:34 The so-called fault is 100 kilometers long from Bulacan, Rizal, here in Metro Manila, to Cavite and Laguna.
00:42 And based on its length, it can reach a magnitude 7.2 earthquake.
00:47 PHIVOX Director Teresito Bacolcol explained that the West Valley Fault last moved in 1658.
00:54 He said that based on the carbon sample data they have, this is the base of the recurrence interval or the movement of the West Valley Fault every 400 to 600 years.
01:04 That's why it is estimated that the big one could happen in 2058.
01:08 But of course, it's not an exact calculation. It could be earlier or it could be later or it could be between 400 years to 600 years or it could be on the upper limit, the 600 years which is 200 years from now.
01:22 Meaning we are on the expected range of the movement of the West Valley Fault.
01:32 Because of this, preparation is important, like the construction of the National Simultaneous Earthquake Drill, especially for Metro Manila, which could affect its movement.
01:42 According to PHIVOX, every region in the country has a so-called big one, and this is for the National Capital Region.
01:48 Based on our studies, we expect around 33,000 casualties. It's only in Metro Manila. And if we include other provinces nearby, Pampanga, Laguna, Bulacan, that would go as high as 48,000 or 50,000.
02:08 The assumption there, the 33,000, he assumed that at 6 p.m., people will be evacuating.
02:17 He also believed that it's impossible to be 100% prepared, but it's better if people are more aware about this fault compared to the past 20 or 30 years.
02:27 We really have to follow and participate in earthquake drills. And we will take it seriously because drills build muscle memory. During actual events, our response would come out naturally.
02:44 The structures that are built above the fault are expected to collapse, but even if it's far away, it's still possible to feel it, especially with the high intensity of 8 in NCR.
02:56 So PHIVOX reminds us that the construction of houses or homes should be strong or earthquake-resilient.
03:03 In the end, according to PHIVOX, it's normal that the country experiences earthquake because the Philippines is in the Pacific Ring of Fire, and this is the reality that we have.
03:12 So it's different to prepare for each one, especially since there is no technology that can tell when and where an earthquake could occur.
03:22 Rod Logusad, for the nation.
