Metro Manila (CNN Philippines, March 4) — The Philippine Institute of Volcanology and Seismology on Thursday raised Alert Level 1 over Mt. Pinatubo in Central Luzon after detecting 1,772 “imperceptible” earthquakes since January 20 this year.

“Given the persistence of seismic activity, DOST-PHIVOLCS is raising the status of Pinatubo Volcano from Alert Level 0 to Alert Level 1,” Phivolcs said in a statement. “This means that there is low-level unrest that may be related to tectonic processes beneath the volcano and that no imminent eruption is foreseen,” the institute added.

The Phivolcs advised against entering the Pinatubo Crater area.

The highest level is Alert Level 5, which indicates that a hazardous eruption is in progress. The lowest is Alert Level 0 when the volcano is quiet.

Mt. Pinatubo last erupted nearly three decades ago. Its 1991 eruption was considered by the U.S. Geological Survey as the second-largest volcanic eruption of the 20th century.
