00:00The Big One, let's clarify first, is not a scientific term.

00:04The Big One, here in our context in the Philippines, is used by our colleagues in the media

00:11to describe a strong earthquake that may or may not happen in Metro Manila.

00:19So when we say Big One, the equivalent of this is the earthquake in Metro Manila.

00:24But in reality, the Big One may happen in every region, in every province,

00:34except for one province, they have their own Big One.

00:39Because here in these places, in these provinces, in these regions,

00:43except for that one province, they have earthquake sources.

00:48And these earthquake sources may generate different earthquake scenarios.

00:54And the strongest earthquake scenario is the one that may be the Big One in their place.

01:00So it's possible that there's a Big One in Metro Manila,

01:04that's the movement of the West Valley Fault, or the movement of the Manila Trench in the West Philippine Sea.

01:10It's possible that there's a Big One in Davao City, because there's the so-called Davao Fault System.

01:16It's also possible that there's a Big One in the Ilocos region, like what happened on July 27, 2022.

01:24It's a magnitude 7 earthquake, but there are still faults there that aren't moving.

01:29There's what's called the West Ilocos Fault System.

01:33We have fellow Filipinos who are listening to BASEI Summer, Eastern Summer.

01:38Actually, their Big One there is not just Big One, but Bigger One.

01:43Because it's possible that there's a magnitude 8 earthquake due to the movement of the Philippine Trench.

01:49So, different scenarios in different regions mean that they have their own Big One.

01:56And it's not just one One, there are many Ones, that's why we call them Big Ones.
