Philippine volcano Taal begins spewing lava

Red-hot lava started gushing out of a Philippine volcano after a sudden eruption of ash and steam that forced villagers to flee and shut down Manila’s international airport, offices and schools.

There were no immediate reports of casualties or major damage from Taal’s eruption south of the capital that began on Sunday, but clouds of ash blew more than 100 kilometres north, reaching the bustling capital and forcing the shutdown of the country's main airport. More than 240 international and domestic flights cancelled so far.

An alternative airstrip north of Manila at Clark freeport remained open, but authorities would shut it down too if falling ash threatens flights, the Civil Aviation Authority of the Philippines said.

The government’s disaster-response agency reported about 8,000 villagers have moved to at least 38 evacuation centres in the hard-hit province of Batangas and nearby Cavite province, but officials expect the number to swell with hundreds of thousands more being brought out of harm’s way. Some residents could not move out of ash-blanketed villages due to a lack of transport and poor visibility, while other refused to leave their homes and farms, officials said.

The government volcano-monitoring agency raised the danger level around Taal three notches to level 4, indicating “an imminent hazardous eruption.” Level 5, the highest, means a hazardous eruption is underway and could affect a larger area with high-risk zones that would need to be cleared of people, said Renato Solidum, who heads the institute.

Authorities continue to detect swarms of earthquakes, some of them felt with rumbling sounds, and a slight inflation of portions of the 311-metre volcano, officials said and advised residents to stay indoors and wear masks and goggles outdoors.
