Seismological Observation and Earthquake Prediction Division


PHIVOLCS Earthquake Bulletins of latest seismic events in the Philippines are listed below. The event parameters (hypocenter, time and magnitude) are determined using incoming data from the Philippine National Seismic Network

Philippine Standard Time (PST) is eight hours ahead of Coordinated Universal Time (UTC). (PST = UTC + 8H) UTC is the time standard for which the world regulates clocks and time.

Earthquakes in this list with their date and time underlined in blue have reported felt intensities. Intensity ratings are based on the PHIVOLCS Earthquake Intensity Scale.
