A small volcano near the Philippine capital that draws tourists for its picturesque setting in a lake erupted with a massive plume of ash and steam Sunday, prompting the evacuation of tens of thousands of people and forcing Manila’s international airport to shut down.
The Philippine Institute of Volcanology and Seismology said Taal Volcano in Batangas province south of Manila blasted steam, ash and pebbles up to 10 to 15 kilometres (6 to 9 miles) into the sky in a dramatic escalation of its growing restiveness, which began last year.
The volcanology institute raised the danger level around Taal three notches on Sunday to level 4, indicating “a hazardous eruption may happen within hours or days,” said Renato Solidum, who heads the volcanology institute. Level 5, the highest, means a hazardous eruption is underway and could affect a larger area.
There were no immediate reports of injuries or damage, but authorities scrambled to evacuate more than 6,000 villagers from an island in the middle of a lake, where the volcano lies, and tens of thousands more from nearby coastal towns, officials said. About 300,000 people were targeted to be moved to safety in Batangas overnight and in the next few days.
“We have asked people in high-risk areas, including the volcano island, to evacuate now ahead of a possible hazardous eruption,” Solidum said.
Fallen ash covered the runways at Manila’s international airport Sunday night. All departing and arriving international and domestic flights were suspended “due to volcanic ash in the vicinity of the airport” and nearby air routes, the Civil Aviation Authority of the Philippines said.
Taal lies around 60 km (37 miles) south of Manila.
Aviation officials also ordered the closure of Clark International Airport north of the capital after ash fell in the area. Authorities said they were considering diverting flights to unaffected airports outside Manila.
The volcanology institute reminded the public that the small island where the volcano lies is a “permanent danger zone,” although fishing villages have existed there for years. It asked nearby coastal communities “to take precautionary measures and be vigilant of possible lake water disturbances related to the ongoing unrest.”
Heavy to light ashfall was reported in towns and cities several kilometres (miles) from the volcano, and officials advised residents to stay indoors and don masks and goggles for safety. Motorists were hampered by poor visibility, which was worsened by rainy weather.
Hotels, shopping malls and restaurants line an upland road along a ridge overlooking the lake and the volcano in Tagaytay city, a key tourism area that could be affected by a major eruption.
Authorities recorded a swarm of earthquakes, some of them felt with rumbling sounds, and a slight inflation of portions of the 1,020-foot (311-meter) volcano ahead of Sunday’s steam-driven explosion, officials said.
One of the world’s smallest volcanoes, Taal is among two dozen active volcanoes in the Philippines, which lies along the so-called Pacific “Ring of Fire,” a seismically active region that is prone to earthquakes and volcanic eruptions.
About 20 typhoons and other major storms each year also lash the Philippines, which lies between the Pacific and the South China Sea, making it one of the world’s most disaster-prone countries.
