Mt. Malinao 

Are you familiar with the volcano next to Mayon?

As part of the Bulkan Ng Bikol series, National Museum Bicol features another peak in the province of Albay.

Mt. Malinao is a stratovolcano located in the central part of the Bicol Volcanic Arc rising at 1,548 meters with a base diameter of ~22.5 kilometers. This Quaternary volcano contains a large summit crater that is breached to the east. Its active neighbor, Mayon Volcano, is 20 aerial kilometers from Malinao.

As per Nielson et al., 1996, Mt. Malinao was active at 0.5 to 0.06 Ma. Its rock type is andesitic according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS). Located on its eastern flank is the site of Luzon’s largest solfataras and hot springs, some of which deposit silicious sinter.

Like Mt. Labo in Camarines Norte, the PHIVOLCS classified Mt. Malinao as a potentially active volcano. Its current activity is fumarolic, where steam and volcanic gases are emitted from the openings in the earth’s surface.
