Philippines evacuates 3,000 villagers after volcano activity raises alert level

MANILA, Philippines — A series of mild eruptions at the most active volcano in the Philippines has prompted the evacuation of nearly 3,000 villagers in a permanent danger zone on its foothills, officials said Wednesday.

Authorities raised the 5-step alert around Mayon Volcano in the northeastern province of Albay to level 3 on Tuesday after detecting intermittent rockfalls, some as big as cars, from its peak crater in recent days along with deadly pyroclastic flows — a fast-moving avalanche of super-hot rock fragments, ash and gas.

Alert level 5 would indicate a major explosive eruption, often with violent ejections of ash and debris and widespread ashfall, is underway.

''This is already an eruption, a quiet one, with lava accumulating up the peak and swelling the dome, which cracked in some parts and resulted in rockfalls, some as big as cars,'' Teresito Bacolcol, the country's chief volcanologist, told The Associated Press.

He said it is too early to tell if Mayon's restiveness would worsen and lead to a major and violent eruption given the absence of other key signs of unrest, like a spike in volcanic earthquake and high levels of sulfur dioxide emissions.

Troops, police and disaster-mitigation personnel helped evacuate more than 2,800 villagers from 729 households inside a 6-kilometer (3.7-mile) radius from the volcano's crater that officials have long designated a permanent danger zone, demarcated by concrete warning signs, Albay provincial officials said.

Another 600 villagers living outside the permanent danger zone have evacuated voluntarily to government-run emergency shelters to be safely away from the volcano, Claudio Yucot, regional director of the Office of Civil Defense, said.

The 2,462-meter (8,007-foot) volcano is one of the Philippines' top tourism draws because of its near-perfect cone shape. But it's also the most active of the country's 24 restive volcanoes.

A terrifying symbol of Mayon's deadly fury is the belfry of a 16th-century Franciscan stone church which protrudes from the ground in Albay. It's all that's left of a baroque church that was buried by volcanic mudflow along with the town of Cagsawa in an 1814 eruption which killed about 1,200 people, including many who sought refuge in the church, about 13 kilometers (8 miles) from the volcano.

The thousands of people who live within Mayon's danger zone reflect the plight of many impoverished Filipinos who are forced to live in dangerous places across the archipelago — near active volcanoes like Mayon, on landslide-prone mountainsides, along vulnerable coastlines, atop earthquake fault lines, and in low-lying villages often engulfed by flash floods.
