Mayon volcano, located about 500 km 310(miles) south of the Philippine capital of Manila, has erupted 49 times since its first documented eruption in 1616.
Authorities have raised the alert status to Level 4 on Dec.20 which means that a hazardous explosive eruption is possible within days, the country's national news agency reported Monday.
More than 9,000 families are being housed in evacuation camps after authorities raised the alert status.
Mayon volcano last erupted in 2006, when about 30,000 people were moved. Another eruption in 1993 killed 79 people but the most destructive came in 1814, killing more than 1,200 people and burying a town in volcanic mud.
