Filipinos take shelter from volcano
Almost all of the 47,000 residents living on the slopes of a rumbling volcano in the central Philippines are in emergency shelters as lava and earthquakes threatened a major eruption.
Low clouds obscured visibility of the smouldering 8,070ft Mayon, towering over coconut farms and rice paddies in coastal Albay province.
"Hazardous eruption ... can happen today or in the next few days," said chief state volcanologist Renato Solidum. "Nobody has a 100% accuracy."
Ash columns were seen rising during a cloud break and Mr Solidum said his team recorded 1,266 volcanic quakes in the last 24 hours, down from nearly 2,000 the previous day. He said that while the quakes were fewer, they were larger.
The emission of sulphur dioxide - an indication of magma rising inside the volcano - was measured at 6,530 tons per day, slightly less than 7,000 tons on Sunday, but still very high, Mr Solidum said. The normal gas emission is 500 tons per day.
"Technically, Mayon volcano is already erupting because lava has oozed out," said Mahar Lagmay, professor of geological studies at the University of the Philippines.
A bigger, explosive eruption was still possible but hard to predict, he said.
In the past week, more than 45,000 residents living in a five-mile zone around Mayon have been transported in army trucks to school buildings and gymnasiums in and around the provincial capital of Legazpi, where they were given sleeping mats and food supplies to last them through the Christmas holidays, said Jukes Nunez, a disaster management official.
Scientists have raised Mayon's alert level to one step below a hazardous eruption. The only higher level is when a major eruption is in progress. Red hot lava flows had reached three miles from the crater accompanied by booming and rumbling sounds, said the Philippine Institute of Volcanology and Seismology.
Experts fear a major eruption could trigger pyroclastic flows - superheated gas and volcanic debris that race down the slopes at high speeds, incinerating or vaporising everything in their path. More extensive explosions of ash could drift toward nearby towns and cities, including Legazpi, about nine miles away.
