MANILA, Philippines — The Philippine Institute of Volcanology and Seismology warned the public that sudden explosions and ashfall could still threaten areas around Mayon Volcano after it spewed ash Monday morning. Two phreatic eruptions occurred on Mayon Volcano from 7:59 a.m. to 8:05 a.m. The steam-driven explosions generated “grayish to grayish white ash plume that rose 300 to 500 meters above the summit before drifting southwest,” Phivolcs said in a bulletin. Last January, Phivolcs declared Alert Level 4, which warned of an imminent hazardous eruption, on Mayon. Mayon is the most active of the country's 22 volcanoes and one of the deadliest.
