Bulusan may erupt anytime – Phivolcs


LEGAZPI CITY, Albay:  A statevolcanologist has  warned the public, specifically mountaineers, not to climb up Mount Bulusan in Sorsogon province at this time as it may explode anytime.

Ed Laguerta, resident volcanologist  of the Philippine Institute of Volcanolgy and Seismology (Phivolcs) in Bicol, gave the warning on Monday as he noted that Bulusan and Mayon in Albay province—two of the country’s most active volcanoes—have continued to show signs of restiveness.

The activity of Bukusan and Mayon has prompted Laguerta to consider another survey of the two volcanoes.

“We want another round of aerial surveys to check the status of Mounts Mayon and Bulusan because inflation and pressure beneath the volcanoes are increasing tremendously,” he said.

Laguerta   added that the most active part of Bulusan is on the west side of the volcano facing the municipalities of Juban and Irosin.

The volcano created at least four craters in previous recorded eruptions, he said.

Its last recorded major eruption took place in 1852.

Bulusan volcano is classified as stratavolcano (composite volcano) and one of the most active volcanoes in the country with a base diameter of 15 kilometers.

Types of eruption exhibited by Bulusan were phreatic (steam-driven), strombolian (quiet effusion of lava) and caldera.

At least 17 recorded eruptions have taken place since 1852.

Bulusan is generally known for its sudden steam-driven   explosions.

With an elevation of 1,547 meters, it is said to have been formed 40,000 years ago.

The volcano  is considered as the 4th most active in the Philippines after Mayon, Taal and Kanlaon.

Bulusan is a local term that means “where the water flows.”
