Mt. Malinao – A Volcano That Helps Generate Electricity p.1






Malinao is a volcano located in the Bicol Region of the Philippines. The stratovolcano has no historical eruption but displays strong fumarolic activity which is harnessed for generating electricity. Located on its slope is Tiwi Geothermal Power Plant, one of the first geothermal energy plant commissioned in the country.

Malinao Volcano is situated between the provinces of Albay and Camarines Sur in the southeastern region of Luzon Island; about 20 km (12 mi) north-northwest of Mayon volcano, the most active volcano in the Philippines.

The mountain is forested with an elevation of 1,548 metres (5,079 ft) asl and a base diameter of 22.5 kilometres (14.0 mi). On the summit of the volcano is a large crater with bare inner walls that is breached on the eastern side. 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. Naglagbong and Jigabo are two thermal wells located on the volcano. Temperatures up to 108 °C (226 °F) were recorded on the fumaroles of Naglagbong. –




Malinao is one of the three peaks of Albay, together with the famous Mt. Mayon and the little-known Mt. Masaraga.

Mt. Malinao is located south of Luzon and northeast of the Bicol Region particularly in the municipality of Malinao in Albay Province. It is a mountain range with an estimated altitude of 1,584 meters above sea level. It is  a potentially active volcano, with Mayon Volcano in its southwest. –
