Langila

Papua New Guinea

5.525°S, 148.42°E; summit elev. 1330 m

All times are local (unless otherwise noted)


Throughout the month Crater 2 produced occasional gentle emissions of pale gray to brown ash clouds, generally low in ash content. There were single Vulcanian explosions on 3, 4, 14, and 19 August that were accompanied by forceful emissions of dark gray ash clouds that rose to ~3,000 m above the summit. Ash clouds were blown NW, producing light ashfalls at settlements 11 km from the volcano. Crater 3 remained quiet throughout August. There was no seismic recording during the month.

Geologic Background. Langila, one of the most active volcanoes of New Britain, consists of a group of four small overlapping composite basaltic-andesitic cones on the lower eastern flank of the extinct Talawe volcano. Talawe is the highest volcano in the Cape Gloucester area of NW New Britain. A rectangular, 2.5-km-long crater is breached widely to the SE; Langila volcano was constructed NE of the breached crater of Talawe. An extensive lava field reaches the coast on the north and NE sides of Langila. Frequent mild-to-moderate explosive eruptions, sometimes accompanied by lava flows, have been recorded since the 19th century from three active craters at the summit of Langila. The youngest and smallest crater (no. 3 crater) was formed in 1960 and has a diameter of 150 m.
