SORSOGON, Philippines - The volume of ash that Bulusan volcano has spewed since its first explosion last October 26 has reached an estimated 466,000 cubic meters, according to state scientists.
The Philippine Institute of Volcanology and Seismology (Phivolcs) thinks the lahar flows are a good thing as long as the rain isn't continuous.
The lahar flows mean that the ash deposits on the volcano are reduced.
The flows remain channel-contained, the Phivolcs said.
Philvocs, however, warned residents living near the lahar channels to monitor the situation and evacuate once rains do not stop for 3 to 4 hours.
On Thursday, residents of Barangay Gulang-gulang in Irosin, Sorsogon province watched as a lahar flows carried large boulders past a bridge.
They expressed fears for their safety should the lahar rise and overflow a channel’s banks.
