Cebu, Philippines- The Philippine Institute of Volcanology and Seismology (PHIVOLCS) said on July 26, 2017 that Cebu has several fault lines that are either active or potentially active.
PHIVOLCS Officer-in-Charge Dr. Renato Solidum, Jr. said that the faults seen in the province have not yet moved.
“Areas that have no major earthquake in the past several hundreds of years would mean that these areas have seismic gap or big earthquake gap that when these faults will move, it may generate a strong earthquake,” said Solidum, also the undersecretary for Disaster Risk Reduction and Climate Change of the Department of Science and Technology.
He also said that the longer period of time the fault has not moved, the more energy it stores.
“Is Cebu safe from earthquakes? The answer is no because there are faults in Cebu that can potentially move,” he said.
The Bogo City and San Remigio town are active faults while the rest of the faultiness across Cebu province are potentially active faults including Daanbantayan Lineament.
Potentially active faults are subdivided into two, the “Central Cebu Fault” which transects the City of Danao, Cebu, Talisay, Naga, and Toledo and the towns of Compostela, Minglanilla, Balamban and the “South Cebu Fault” which transects Carcar City and the towns of Sibonga, Argao, Moalboal, Badian, Alegria, Dalaguete, Alcoy, and Boljoon.
Solidum said that other towns and cities have no fault lines and may not be affected by the ground rupture if an earthquake occurs but will still be affected by the shaking.
Asked what damage these ground movements will cause in the event of an earthquake, Solidum responded indirectly, saying only that every city or town in the country will experience their own ‘big one’ at a certain point.
He also said that this is not to scare the people in Cebu but for them to know the possible risks that this earthquake can have.
“Cebu City is a very important city in the Philippines not only being one of the centers of governance but also in business. The effects in Cebu will also affect a big part of the country and also the whole of Cebu province,” he said.
Solidum also said that we should learn a lesson from the recent magnitude 6.5 earthquake that struck Leyte last July 6, 2017.
