Mount Malinao is a potentially active[3] stratovolcano located in the Bicol Region of the Philippines.
The mountain is forested with an elevation of 1,657 metres (5,436 ft) above sea level and a base diameter of 22.5 kilometres (14.0 mi).
On the lower flank this side of the predominantly andesitic volcano, is Luzon's largest solfataras and hot springs, some of which deposit siliceous sinter.
[8][9] The Philippine Institute of Volcanology and Seismology (PHIVOLCS), the government bureau that deals with volcanism in the country classifies Malinao as a potentially active volcano.
[5] There was an increase in seismicity in 1970 accompanied by rumbling noises in Malinao prompting an issue of warning that the mountain might be reactivating.
