Mt. Bulusan restive
by BA Recebido
SORSOGON CITY (11 April) -- Alert Level 1 has remained in effect over Bulusan Volcano and the public is reminded not to venture into the four-kilometer radius Permanent Danger Zone (PDZ) because the area is at risk of sudden steam or ash explosions, the Philippine Institute of Volcanology and Seismology (Phivolcs) said on Monday.
Volcanologists are paying closer attention to Bulusan Volcano in Sorsogon province aside from Mayon Volcano in Albay and the relatively waking up of Taal Volcano in Batangas.
In Sorsogon, after Sunday's 5:45 am ash explosion, another explosion type earthquake occurred at around 6:11 a.m. Monday, a smaller one compared to previous activities which does not yet guarantee a waning of the restiveness of the volcano, prompting Phivolcs to re-deploy one of the instruments in Mayon Volcano Observatory in Albay to Sorsogon station for the Mt. Bulusan watch.
The institute said latest seismic event was recorded by the seismographs around Bulusan Volcano for about 20 minutes and, during the event, nearby residents reported rumbling sounds coming from the volcano.
But the Phivolcs was not able to conduct visual observation due to thick rain clouds covering the summit area of the volcano. During the past observation period, the seismic network recorded a total of nine high frequency and one explosion type volcanic earthquake during the past 24 hours.
The Phivolcs warned that the residents of areas beyond the PDZ that are downwind of the crater are likely to be affected by ash falls during explosions.
Residents near river channels were advised against life-threatening lahar flows as ash and other loose volcanic materials might be remobilized during bad weather conditions or when there is heavy and prolonged rainfall. (PNA/PIA Sorsogon) [top]
