More Earthquake Warnings: Swarm With > 800 Quakes Hits Below 'Dangerous' Stratovolcano In Philippines

Will Pinatubo open the year with a big bang? Swarm with more than 800 earthquakes hits below the dangerous stratovolcano in the Philippines

Strange Sounds

Mount Pinatubo is most notorious for its VEI-6 eruption on June 15, 1991, the second-largest terrestrial eruption of the 20th century after the 1912 eruption of Novarupta in Alaska.

But will the dangerous volcano open the year with a bang?

Philvocs is currently watching Pinatubo after a series containing around 826 small earthquakes hit below the volcano.

The official Philvocs report

This is to notify the public and concerned authorities of recent earthquake activity in Pinatubo Volcano.

Since 20 January 2021, the Pinatubo Volcano Network (PVN) and the Philippine Seismic Network (PSN) have detected a total of 826 imperceptible earthquakes east-northeast of Pinatubo Volcano in the vicinities of the City of Mabalacat, Pampanga.

The strongest of these earthquakes occurred on 25 January at depths of 15-28 kilometers and ranged between ML1.0 and ML2.5 in magnitudes.

Based on the general distribution of located events, these earthquakes were generated along a segment of the Sacobia Lineament, a fault that was last active during the post-eruption period of 1991.

This development serves to remind us once again that several faults are situated around the volcano and that these can generate earthquake activity that can be sometimes imperceptible and harmless but that can also sometimes be damaging
