The Philippine Institute of Volcanology and Seismology (Phivolcs) detected a total of 26 volcanic earthquakes in Mt. Pinatubo from Sunday, April 25, to Monday, April 26.
In a volcano bulletin issued on Monday morning, Phivolcs said that Alert Level 1 will remain over Mt. Pinatubo due to low-level unrest that may be related to tectonic processes beneath its edifice.
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."
"Entry into the Pinatubo Crater area must be conducted with extreme caution and should be avoided if possible," Phivolcs advised.
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.
