The Philippines' most active volcano is threatening to erupt after oozing lava for the first time in years. The 2460m Mayon volcano, located above Legazpi city about 340km southeast of Manila, has been rocked by dozens of volcanic earthquakes.
Thousands of villagers have been evacuated as authorities raised the alert level to two steps below eruption. The mountain last exploded in 2006, which was closely followed by a typhoon and mudslide in the region that killed over 1000 people.
Incandescent lava fragments were seen continuously detaching from the crater of Mayon Volcano (13.2576 N, 123.6856 E), which come to rest on the upper and middle slopes, about 3 kilometers from the summit. These events were detected by the seismic network as high frequency volcanic tremor with maximum trace amplitude of 10 millimeters. During the preceding 24 hours, the seismographs recorded eighty-three (83) volcanic earthquakes. Sulfur dioxide emission rate using FLYSPEC increased from the previous 535 tonnes per day (t/d) to about 757 t/d measured yesterday morning.
Increased Tendency Towards Eruption
Relatively High Unrest
Volcanic quakes and tremor may become more frequent.
Further increase in SO2 flux.
Occurrence of rockfalls in summit area.
Vigorous steaming / sustained crater glow.
Persistent swelling of edifice.
Vulcanologists said the alert level around Mayon had been raised to number 3, indicating volcanic materials were now near the top of the crater. Level 4 means an eruption is imminent while Level 5 means an eruption is already in progress.

This is to notify the public that PHIVOLCS-DOST is now raising the alert status of Mayon Volcano (13.2576 N, 123.6856 E) from ALERT LEVEL 3 to ALERT LEVEL 4. This means that a hazardous explosive eruption is possible within days, thus, areas expected to be affected by such eruption will be accordingly extended.
