Location
Balut Island, the westernmost of the Sarangani Islands, is the larger, higher, and better cultivated than Sarangani Island. In the center of the island is Balut Volcano, which is fumarolic on occasion. With an elevation of 2828 feet (862 m), if seen from the northwest, it appears between two peaks. Near the southwest point there is another volcano and in the southeast part is Ten Seventy Hill with an elevation of 1083 feet (330.1 m). The north and east coasts are bordered by a reef, which in some places extends out over 1 mile, while on the south and west sides the fringing reef does not extend out to any distance. Off the southwest point is a rock 40 feet high. Lajan Point, the northeast point of the island, is low and covered by mangroveMangrove
Mangroves are various kinds of trees up to medium height and shrubs that grow in saline coastal sediment habitats in the tropics and subtropics – mainly between latitudes N and S...

Volcanic Activity
There are no reports of eruptions in historical times. The January 4, 1641 eruption which enveloped most of Mindanao in darkness was falsely attributed to Balut volcano, as well as to other volcanoes in the Philippines. Later studies proved that the eruption came from Mount ParkerMount Parker

Geology
Rock type on the volcano is predominantly basaltBasalt
Basalt is a common extrusive volcanic rock. It is usually grey to black and fine-grained due to rapid cooling of lava at the surface of a planet. It may be porphyritic containing larger crystals in a fine matrix, or vesicular, or frothy scoria. Unweathered basalt is black or grey...
and andesite
Andesite
Andesite is an extrusive igneous, volcanic rock, of intermediate composition, with aphanitic to porphyritic texture. In a general sense, it is the intermediate type between basalt and dacite. The mineral assemblage is typically dominated by plagioclase plus pyroxene and/or hornblende. Magnetite,...

Earthquake
An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves. The seismicity, seismism or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time...
