Background

Langila volcano, whose activity record goes back to the 19th century only, is one of the most active volcanoes of New Britain, Papua New Guinea. Langila's frequent activity consists typically of mild-to-moderate explosive eruptions, that are sometimes accompanied by lava flows.

The volcano consists of four small overlapping cones on the lower eastern flank of the extinct Talawe volcano,- the highest volcano in NW New Britain. The rectangular, 2.5-km-long crater of Talawe has a large gap to the SE; the younger Langila volcano formed NE of Talawe's breached crater.

Extensive lava flows have reached the sea from the N and NE flanks of the volcano. Since observations have begun, 3 summit craters have been active. The youngest and smallest of these, with a diameter of 150 m, was formed in 1960.

A third tectonic setting where volcanism occurs is believed to be the result of mantle plumes and not directly related to plate boundaries. So called hot spot volcanoes fall into this category.
