Philippines shuts more schools as volcano spews ash , lava

The Philippines' most active volcano spewed lava that cascaded downslope and emitted ash that fell on nearby towns, state volcanologists said on Tuesday, prompting to shut more schools.

Mount Mayon, a volcano in the coconut-growing central Bicol region that draws tourists because of its near-perfect cone shape, has shown increased restiveness since Saturday, displacing thousands of residents.

Phivolcs said the advancing lava and pyroclastic flows had reached the six-kilometre radius no-go zone, from which some residents fled.

"Alert level 3 remains in effect over Mayon Volcano, which means that it is currently in a relatively high level of unrest as magma is at the crater and hazardous eruption is possible within weeks or even days," it said.

Alert level 4 means an eruption is possible "within days" while level 5 is when a hazardous eruption is under way.

The Albay provincial government has expanded its class suspension order to include more towns around the 2,462-metre volcano, and advised travellers to avoid ashfall-hit villages amid poor road visibility, reports Reuters.

Class suspensions have allowed the government to use schools as temporary shelters for displaced people.
