Geographic context The Philippines lies along the Pacific Ring of Fire, where the Pacific Plate meets surrounding tectonic plates, according to the Philippine Institute of Volcanology and Seismology and the U.S. Geological Survey. This location creates numerous active faults and trenches capable of generating strong earthquakes.

Earthquake damage depends on factors including depth, local geology, population density, and construction quality, the United Nations Office for Disaster Risk Reduction states.
