ILOILO CITY, April 8 – Director Renato U. Solidum Jr. of the Philippine Volcanology and Seismology (Phivolcs) underscored the need for disaster preparedness which is not limited only to earthquakes but also its hazards like liquefaction, ground shaking, fire, landslide and even a possible tsunami.
Solidum who was the guest of honor during the quarterly meeting of the Regional Disaster Risk Reduction and Management Council here Friday, stressed that “preparedness and risk reduction is everyone’s business” and it should start by educating people what they need to know.
He explained that an active fault known as West Panay Fault is present in the Panay Island.
The Madia-as Mountain Range as a matter of fact is a result of the collision between Palawan micro-continental block that separated from mainland Asia and met Panay Island, he said.
He added that collision is still going on and from time to time there are tremors that can be felt.
The latest major earthquake recorded was in June 1990 that affected Culasi, Antique and parts of Aklan.
The strongest ever recorded was the 8.3 magnitude earthquake that happened in 1948. It damaged 55 churches in Panay Island with 17 to have totally collapsed and 20 had cracks beyond repair. Also, it was reported that 50 percent of the houses in Antique were ruined and two persons died.
While everyone has to be thankful that so far no major earthquake has occurred in the region still there is no reason to be complacent because there is a possibility that it may happen.
Meantime, the western coastline of Western Visayas happened to be part of the major Sulu trench. Solidum said that areas with coastlines located within the trench are prone to tsunami.
He disclosed that the 1897 earthquake recorded offshore of Zamboanga Peninsula generated a Sulu seawide tsunami that also affected southern Negros and Negros Panay.
However, he clarified that a tsunami will only happen if there is a major earthquake that is associated with the vertical movement of the ocean floor.
Meanwhile, making preparations vary depending on where the active faults are situated, he said.
Further, he urged everyone to learn lessons from previous disasters, among others is to ensure that they are still alive after the disaster for them to be able to help those who are affected. (PNA) LAP/PGL/vlo
