Yesterday, Phivolcs said it recorded “a steam-driven explosion from a vent on its northwest upper slopes that propelled an ash plume approximately 250 m high before it drifted west.”
“Traces of ash were observed in Sitio Tulay of Brgy. Bagsangan, Cogon, Monbon, and Tinampo in Irosin, Sorsogon,” the report added.
On May 1, the institute reported a similar steam-driven explosion, which are typical to the volcano during restive periods.
“Based on past records, more explosions can be expected to occur with varying intensity, duration and distribution of ash,” it warned.
In the same bulletin, Phivolcs reminded local government units and the public “that entry to the 4-kilometer radius Permanent Danger Zone (PDZ) is strictly prohibited due to the possibility of sudden and hazardous steam-driven or phreatic eruptions. Civil aviation authorities must also advise pilots
to avoid flying close to the volcano’s summit as ash from any sudden phreatic eruption can be hazardous to aircraft. Furthermore, people living within valleys and along river/stream channels should be vigilant against sediment-laden stream flows and lahars in the event of heavy and prolonged rainfall.”
Meanwhile, the Office of Civil Defense-Regional Disaster Risk Reduction Management Council (OCD-RDRRMC) this morning said it conducted an initial briefing on the status of Bulusan Volcano to the Sorsogon Provincial Disaster Risk Reduction and Management Council.
It already deployed a team, which includes Engr. Raden Dimaano and resident volcanologist Ed Laguerta, in Irosin town.
OCD-RDRRMC has already started to distribute disposable masks to residents of Irosin.
Said office is presently on heightened alert for the monitoring, coordination, and management of the incident.—BICOLSTANDARD.COM. Pirming enot. Pirming bago.
