The Mayon in the Philippines erupted today for the third time this year. The VAAC Tokyo reports volcanic ash at a height of 4 km. PHILVOLCS yesterday recorded 2 volcanotectonic earthquakes and a seismic rockfall signal triggered by a debris avalanche that produced a small ash cloud. At night a weak glowing was observed above the crater. Satellite photos show a clear thermal anomaly indicating that the volcano is heating up. Sulfur dioxide emissions are just under 1000 tons a day. The alarm level is set to “2”.
