SAN ANTONIO, Zambales—For two consecutive days, the Philippine Institute of Volcanology and Seismology (Phivolcs) recorded a series of earthquakes at Mt. Pinatubo, which remained on Alert Level 1.
Phivolcs’ observation in the last 24 hours showed that three more volcanic earthquakes were registered at Pinatubo on Monday (July 12). These quakes were related to tectonic processes under the volcano.
According to Phivolcs, while the volcano is on Alert Level 1, which means there is a low level of unrest, no imminent eruption was expected.
In the previous day, two volcanic earthquakes were also registered around Pinatubo.
Phivolcs recommends extreme caution when venturing near Pinatubo’s crater.
The volcano was first placed on Alert Level 1 in March this year after a series of imperceptible or not easily noticed earthquakes that began in January.
It was the first time that Phivolcs elevated the warning status in Mt. Pinatubo since 1996 when it was placed on normal status.
Mt. Pinatubo encompasses the boundaries of Pampanga, Tarlac, and Zambales provinces.
