Expected to be affected are Ranggas Channel in Barangay Aniog, Juban town, and Cogon Channel in Barangay Cogon in Irosin.

Henry Imperial, Philippine Institute of Volcanology and Seismology (Phivolcs) research assistant specialist based in Barangay Cabid-an, Sorsogon City, said heavy rains will surely carry the old and new ash deposits brought about by the explosions on May 1 up to June 23.

Imperial said that although the new deposits are still not huge, the old ones were large enough to cause the lahar threats.

He warned villagers living near the affected river channels to be on alert and be always ready to move to safe place in case of heavy rains.

Dr. Ed Laguerta, Phivolcs resident volcanologist, said the rains being experienced in the area are due to thunder storms.

Although these are strong, Laguerta said, these could not bring strong lahar flows.

What is threatening are strong and sustained rains in the area of the volcano, he added.

Engineer Raden Dimaano, Sorsogon Provincial Disaster Risk Reduction and Management Office, said his office has already pre-positioned food supply in the three towns of Sorsogon where the threats from the Bulusan Volcano are most feared -- Irosin, Juban and Bulusan.

Dimaano also assured the public of enough supply of medicines that the villagers need in case they would be affected by Bulusan’s abnormal situation.

Despite these threats, however, the situation in the province is generally normal, he said.

Two volcanic earthquakes were recorded during the past 24 hours. (by Nancy Ibo Mediavillo, PNA)
