LEGAZPI CITY, Philippines – Bulusan Volcano spewed ash again yesterday morning, the second time this week.

Eduardo Laguerta of the Philippine Institute of Volcanology and Seismology (Phivolcs) said the steam-driven eruption that reached a kilometer high occurred at around 4:58 a.m. and lasted for nine minutes.

Volcanic ash blanketed Barangays San Rafael, Sabang and Mabuhay.

Phivolcs said at least 28 volcanic quakes were also recorded in the past 24 hours.

The agency said alert level 1 remains in effect, which means more steam-driven eruptions are expected.

Phivolcs warned the public and concerned local government units that entry into the four-kilometer permanent danger zone is prohibited due to sudden and steam-driven eruptions.

On Tuesday afternoon, Phivolcs extended the danger zone on the southern flank of the volcano by two kilometers.

The southeast vents, which “pose a potential source of eruption” is near Barangays Mapaso, Irosin and San Roque.

Phivolcs warned villagers near rivers and streams around the volcano against sediment-laden and lahar flows during heavy rainfall. – With Helen Flores
