Manila: Three volcanoes in the Philippines are currently active, with one showing signs of near eruption and the rest initial signs of heating up, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
Taal Volcano in Batangas, southern Philippines, had 19 volcanic quakes within 24 hours, Phivolcs said in a Saturday update.
The temperature at the main crater's lake increased from 30.5 to 31.5 degrees Celsius, Phivolcs said, adding that Taal's magma was nearing the surface.
Alert level two remained hoisted on Taal since last week, prompting residents to return to the crater's danger zone.
Meanwhile, four quakes were recorded in Bulusan Volcano and one in Mayon Volcano, both in the Bicol Region in southern Luzon, Phivolcs said.
The Philippines has 22 active volcanoes. It is part of the Asia Pacific's Ring of Fire where earthquakes and volcanic eruptions always occur.
