Mt. Bulusan spews 3-km ash column — Phivolcs

Mt. Bulusan in Sorsogon spewed a three-kilometer ash column Monday morning, covering several villages in its southwest with ash, the Philippine Institute of Volcanology and Seismology said.

In its advisory, Phivolcs said Bulusan had an ash explosion at about 9:12 a.m.

A day before the explosion, two volcanic earthquakes were recorded in the volcano, the agency said.

Much of the ash from the eruption drifted over the towns of Irusan in the southwest of the volcano. The restive volcano has been showing seismic and steaming activities since November.

Bulusan Volcano’s status remains at Alert Level 1. This means that the source of activity is hydrothermal and shallow.

Phivolcs bans the entry into the four-kilometer radius Permanent Danger Zone (PDZ) since the area is at risk to sudden steam and ash explosions. (report from Kristine Alave, Philippine Daily Inquirer)
