Mount Bulusan, an active volcano in Sorsogon in the Bicol region, spewed a 250-meter-high ash cloud at 9:46 p.m. on Wednesday , according to resident volcanologist Ed Laguerta of the Philippine Institute of Volcanology and Seismology (Phivolcs). In an eruption notification posted through its Facebook page, the Office of Civil Defense in Bicol said that the ash explosion was generated by an earthquake. “The explosion event lasted 3.5 minutes based on the seismic records,” Phivolcs reported on its bulletin posted at its website at 8:00 a.m. on Thursday.

At the same time, Phivolcs raised Alert Level 1 over the area, meaning the volcano has started showing abnormal activity. Based on an initial assessment, Laguerta said that there were light ashfalls over barangays of Cogon, Tinampo, Monbon and Agasan in the town of Irosin. Last Friday morning (May 1), a five-minute long ash explosion also occurred at Mount Bulusan. Phivolcs said that a total of 62 volcanic earthquakes were recorded in the next eight hours after the explosion. Local government units and the public have been advised not to enter the volcano’s four-kilometer permanent danger zone.
