Summary
Philippine authorities have raised the alert status of the country's most active volcano to level 4 and established an extended danger zone around it, saying an eruption is imminent. The status change at the Mayon volcano means that a hazardous explosive eruption is possible within days, according to the Philippine Institute of Volcanology and Seismology. Earlier Sunday, the institute said the central Philippine volcano continues to exhibit a high level of activity, adding that 222 volcanic quakes and tremors have been recorded in recent days. One was an explosion-type earthquake that launched a cloud of ash about 1,640 feet (500 meters) into the air, according to an institute statement. The institute recommended extending already-established danger zones of nearly five miles (8 kilometers) south of the summit and 4.3 miles (7 kilometers) north of the summit.
