Mt. Bulusan

SORSOGON, Philippines— The Philippine Institute of Volcanology and Seismology (Phivolcs) on Sunday (May 5) raised Alert Level 1 over Mount Bulusan due to increased seismic activity.

From May 4 to 5, Phivolcs has recorded a total of 16 volcanic earthquakes, according to the agency’s Bulusan Volcano Bulletin on Sunday.

It also noted the active volcano’s tilt data from April 29 to May 5 which indicated a slight inflation in the upper slopes.

The agency also observed increase in water temperature of nearby hot springs.

Phivolcs said that raising Alert Level 1 or abnormal status “indicates that hydrothermal processes may be underway beneath the volcano that may lead to steam-driven eruption.”

With increase volcanic activity, the agency reminds residents and local government units (LGU) near the volcano to avoid entry into the 4-kilometer Permanent Danger Zone (PDZ) around the volcano.

The agency also urges vigilance in the Extended Danger Zone or areas two kilometers beyond the PDZ, “due to the possibilities of sudden and hazardous phreatic eruptions (steam but no lava), rockfall and landslide.”

Likewise, aircraft pilots are advised to avoid flying near the volcano’s summit because ash from an eruption is hazardous. – Marje Pelayo

Power, communication lines still down in Gubat, Sorsogon after ‘Tisoy’ fury

MANILA, Philippines – Power and communication lines in the town of Gubat in Sorsogon are yet to be restored two days after typhoon ‘Tisoy’ (international name: Kammuri) unleashed its wrath starting late Monday.

Tisoy’s violent winds and heavy rains ripped off roofs, toppled trees and knocked down power and telecommunication lines when it first made landfall in Gubat, Sorsogon at 11 p.m. on Monday.

The typhoon hit land three times after it pummeled Gubat – San Pascual, Burias Island in Masbate at 4 a.m. on Tuesday; Torrijos, Marinduque at 8:30 a.m. and in Naujan, Oriental Mindoro at 12:30 p.m.

Tisoy forced thousands of residents to flee their homes and seek temporary shelter as the storm barreled through provinces.

As the typhoon weakened and headed outside of the Philippine area of responsibility, residents in Gubat have started returning home and clearing the destruction left by Tisoy.

Schools resumed classes on Wednesday and residents have returned to their normal activities.

However, many are still grappling with the lack of electricity and unstable communication lines in the town.

Most people have to travel 20 kilometers going to Sorsogon City in order to get a signal on their mobile phones and communicate with their relatives after telecommunication towers were damaged by the storm.

Some residents were also forced to wait in line just to have the battery of their mobile devices charged in a station that opened at the capitol of Sorsogon.

Local authorities said it may take a few weeks before power and telecommunication lines will be restored in the province.

Aside from Gubat, nearby areas such as Prieto Diaz and Barcelona are also experiencing difficulty after telecommunication facilities were damaged by Tisoy. – RRD (with details from Correspondent Roderic Mendoza)
