LEGAZPI CITY, June 15 (PNA) -- The Philippine Institute of Volcanology and Seismology (Phivolcs) has warned mountain climbers or mountaineers to avoid climbing the Bulusan Volcano due to the danger posed by a sudden phreatic explosion.
Dr. Ed Laguerta, Phivolcs resident volcanologist, said the present condition of the volcano could not indicate when it would explode.
Laguerta said that aside from ash, there are rocks deposited along the slopes that could slide down if there are individuals, especially within the four-kilometer Permanent Danger Zone (PDZ).
He explained that this is the behavior of Mt. Bulusan where Alert Level I has been up since last year due to the series of explosions that have occurred in the volcano since May last year.
Before the recent explosion on Friday, there was as similar episode that happened on Feb. 22.
Laguerta said that on April 9, the Phivolcs recorded another eruption, followed by another on May 10.
He said that a day before the Friday phreatic explosion, the Phivolcs registered 113 volcanic quakes as a result of increase in the temperature of water inside the volcano.
Laguerta warned that once the volcano erupts again, the areas that would be affected are the towns of Casiguran, Juban, Barcelona and Bulusan due to the southwest monsoon.
In this connection, Crispolo Deolata of Phivolcs Sorsogon, said their office did not register any quake during the past 24-hour observation period. (PNA) BNB/FGS/NIM/CBD/EDS
