TAGAYTAY (AP, PHILIPPINE DAILY INQUIRER/ASIA NEWS NETWORK) - An erupting Philippine volcano remains life-threatening despite weaker emissions and fewer tremors, an official said on Friday (Jan 17), and advised thousands of displaced villagers not to return to the danger zone.
The Taal volcano emitted weaker ash and steam explosions on Thursday and Friday, the sixth day of its eruption. But despite the "seeming lull", its continuing volcanic quakes, the drying of its crater lake and other signs indicate magma is moving beneath the volcano, said Ms Maria Antonia Bornas, an official at the Philippine Institute of Volcanology and Seismology (Phivolcs).
"When there is an explosion, that will be life-threatening, especially if people get very near, like on volcano island," Dr Renato Solidum, who heads the institute, told The Associated Press.
Since Sunday, the volcano has remained at alert level four, the second-highest warning of a volcano's danger, indicating a hazardous explosive eruption is possible in hours or days.
The Philippine Seismic Network, according to Phivolcs, said it plotted a total of 634 volcanic earthquakes since 1pm on Sunday.
Dr Solidum said assessing whether the volcano's restiveness has eased may take up to two weeks.
Tens of thousands of people have been evacuated from areas now under a security lockdown, and soldiers and police have been stopping desperate villagers from returning to retrieve belongings and save their poultry and cattle. Police have allowed batches of residents to check their homes briefly during the day in some high-risk villages.
Many houses and farms have been damaged by volcanic ash, though no deaths or major injuries directly caused by the eruption have been reported. The authorities have reported one traffic fatality on an ash-slickened road and an evacuee dying from a heart attack.
About 125,000 people fled their homes just in hardest-hit Batangas province, more than 65km south of the capital, Manila. At least 373 evacuation sites were crammed with displaced villagers and needed more ash masks, portable toilets, bottled water and sleeping mats, according to a provincial disaster-response office.
The government's main disaster agency reported that a little more than 77,000 people were displaced in Batangas and the nearby provinces of Cavite and Laguna. The reason for the discrepancy was not immediately clear.
Among those displaced are about 5,000 people who live on the island where the Taal volcano lies. The island is a popular tourist destination renowned for its stunning view of the volcano's crater lake and lush hills teeming with trees and birds. Defence Secretary Delfin Lorenzana has recommended that villagers not be allowed back.
The 311m Taal is the second-most restive of about two dozen active volcanoes across the Philippines. The archipelago lies in the Pacific Ring of Fire, the string of faults around the ocean basin where much of the world's seismic activity occurs.
