The Philippine Institute of Volcanology and Seismology (Phivolcs) recently shed light on the potential consequences of powerful earthquakes that could strike anywhere in the Philippines, except for Palawan.
According to Phivolcs Supervising Science Research Specialist Jeffrey Perez, the "Big One" – a massive earthquake – is a looming threat for every region and province in the country. The exception for Palawan is due to the lack of identified earthquake sources within the island. However, strong tremors might still be felt in Palawan even if the epicenter lies elsewhere.
Phivolcs painted a vivid picture of the devastation a powerful earthquake could bring. Perez explained that an intensity 8 earthquake, categorized as "very destructive," could be so strong that people would struggle to maintain their footing even outdoors (halos hindi na makatayo). Panic would likely erupt as poorly constructed buildings and structures crumble or sustain significant damage.
Among the critical pillars of earthquake preparedness is the role of schools and educational institutions.
Examples of past earthquakes with similar intensity were provided. Residents of Baguio, Dagupan, La Union (1990 Luzon earthquake), Bohol Island (2013), Davao, Davao del Sur, and nearby areas (2019), and Abra (May 2022) all experienced the terrifying force of intensity 8 earthquakes.

Landslides and liquefaction are additional hazards associated with strong earthquakes. Perez highlighted the over 5,000 landslides mapped after the 2019 quake, with Abra experiencing over 1,000 landslides itself. Disruptions to lifelines, including power outages, water shortages, and loss of cellphone signal, are also likely consequences.
We dug deep into this event to get the total picture of its severity and impact.
Phivolcs emphasized the importance of earthquake preparedness in light of these potential dangers. Participation in earthquake drills was strongly encouraged to ensure communities are ready to face a major earthquake.
The institute stressed the significant economic impact of a major earthquake. According to a 2013 Phivolcs and University of the Philippines Diliman Institute of Civil Engineering (UPD ICE) Risk Analysis Project, the Philippines could face P2.5 trillion in economic losses. The project also estimated a grim human cost, with 37,000 potential fatalities and 605,000 injuries ranging from minor to life-threatening.
To stay informed and prepared, Phivolcs encourages the public to visit faultfinder.phivolcs.dost.gov.ph and hazardhunter.georisk.gov.ph. By understanding the risks and taking necessary precautions, the Philippines can be better equipped to face the challenge of powerful earthquakes.
