MANILA (UPDATE) — Another phreatic or steam-driven eruption was detected at the Bulusan Volcano, the Philippine Institute of Volcanology and Seismology (Phivolcs) said Sunday.
In an advisory, Phivolcs said the eruption occurred at 3:37 a.m. Sunday and lasted for 18 minutes. However, the plume was not visible in the agency's camera monitors.
The new phreatic eruption came exactly a week after Bulusan erupted on June 5.
Phivolcs reiterated in its advisory that Alert Level 1 remains in Bulusan, which means that it is in an abnormal condition.
Under Alert Level 1, the public is prohibited from the volcano's 4-kilometer Permanent Danger Zone.
The Municipal Disaster Risk Reduction and Management Office (MDRRMO) in Juban, Sorsogon reported that 12 barangays were affected by ashfall following the latest eruption: Puting Sapa, Añog, Buraburan, Bacolod, Rangas, Roroy, Sipaya, Maalo, Calateo, Cogon, South Poblacion, and North Poblacion.
A family in Barangay Añog immediately fled their home following the eruption.
But as of writing, the MDRRMO in Juban has yet to release the number of evacuees due to the ashfall.
A preemptive evacuation was implemented on Friday due to volcanic earthquakes recorded in Mt. Bulusan. About 109 families in Barangay Puting Sapa fled their homes.
Hours after the eruption, Sorsogon Gov. Francis Escudero ordered local authorities to clean up the Maharlika Highway that was covered in ash.
Resident Ryan Lagunilla managed to take photos and videos of Bulusan's second eruption.
He said the eruption took him by surprise, as he did not expect the volcano to erupt in the wee hours of the morning.
"Nabigla po kasi inaabangan po namin ang pagputok ng bulkan tapos madaling araw sumabog. At wala pa naman po ako sa bahay namin, nasa bahay ako ng kaklase ko may tinatapos po na mga school papers po," Lagunilla said.
(I was surprised because we have been waiting for the volcano to erupt but it erupted early in the morning. I was at a classmate's house finishing some schoolwork when it erupted.)

He added that he was awakened by the successive text messages from the National Disaster Risk Reduction and Management Council (NDRRMC) on developments of Bulusan's eruption.
