Lava cascades down the slopes of Mayon volcano in Legazpi city, Albay province, at dawn Tuesday Dec. 15, 2009 about 500 kilometers (310 miles) south of Manila, Philippines. The Philippine Institute of Volcanology and Seismology, PHIVOLCS, has raised the five-alert level to three following increased activity of the country’s most active volcano and residents are prohibited from venturing into the 6-kilometer (4 miles) permanent danger zone. In December 2006 ash deposits from a previous eruption rolled down its slopes at the onslaught of a typhoon killing more than a thousand residents living around the cone-shaped volcano.
