The Philippine Institute of Volcanology and Seismology (Phivolcs) has recorded a total of 27 earthquakes in Mt. Pinatubo from Saturday, May 22, to Sunday, May 23.
In a volcano bulletin issued on Sunday, Phivolcs said that Alert Level 1 prevails over Mt. Pinatubo due to "low-level unrest" that may be related to tectonic processes beneath the volcano.
The active volcano in Central Luzon has been under an "abnormal" state since March 4, 2021, when Phivolcs raised its status to Alert Level 1.
However, it clarified that "no imminent eruption is foreseen."
Nevertheless, Phivolcs said entry into the Pinatubo crater area must be conducted with extreme caution and should be avoided if possible.
It also asked communities and local government units surrounding Mt. Pinatubo to remain prepared for both earthquake and volcanic hazards and to review, prepare and strengthen their contingency, emergency, and other disaster preparedness plans.
