PHIVOLCS warns vs. magnitude 8 quake in Bicol
Solidum made the warning over Bombo Radio-Legazpi that a magnitude 8 earthquake may occur in Bicol as the Philippine Trench on which Bicol sits is active and is colliding with the Philippine Sea.
“The Philippine Trench is active and can trigger up to magnitude 8 earthquake in the future. So we need to be ready always,” Solidum said.
Said trench is the result of the collision of earth plates and is regarded by scientists as the deepest point in the planet.
In 2013, a magnitude 7.2 earthquake hit Bohol and Cebu in Central Visayas, the deadliest earthquake to occur in the Philippines after 23 years.
The Philippine Trench, also called the “Philippine Deep”, “Mindanao Trench” and “Mindanao Deep,”stretches with a length of approximately 1,320 km and a width of around 30 km from the northeastern top of Luzon up to the Indonesian Island of Malacca Halmahera.
Its deepest depth was measured at 10,540 meters below in its deepest point, the Galathea Depth.
Last week, a magnitude 6.2 earthquake shook Gigmoto, Catanduanes.
Intensity 3 was also reported in Bulusan, Sorsogon, though there was no damage reported.
“Expect aftershocks to occur after the occurrence of 6.2 magnitude earthquakes,” Solidum warned.
The Phivolcs said the earthquake was also felt in other provinces of Bicol, while Intensity III was felt in Jose Panganiban, Sorsogon City, Legazpi City, Irosin and Prieto Diaz – all in Sorsogon; Intensity II in Naga City, Masbate City, Quezon City; and Intensity 1 in Manila. (PNA)
