The Philippine Institute of Volcanology and Seismology (PHIVOLCS) has placed Mt. Pinatubo under alert level 1, following the detection of low-level unrest in the volcano.
Since January of last year, there have been over 1,700 imperceptible earthquakes beneath Mt. Pinatubo, however, this activity and the recent detection of PHIVOLCS, does not indicate imminent eruption.
PHIVOLCS has still advised that entering the crater area of the volcano be avoided if possible, or done with extreme caution.
Meanwhile, the local authorities of Central Luzon will continue to monitor the situation, as nearby communities review their disaster preparedness measures.
Mt. Pinatubo, an active stratovolcano, last erupted on June 15, 1991 and was the second largest volcanic eruption of the 20th century.
