Papua New Guinea
5.525°S, 148.42°E; summit elev. 1330 m
All times are local (unless otherwise noted)
Activity . . . continued at a low level in October except for a single explosion on the 9th, which produced a dark brown ash column ~300 m high. Weak-moderate white vapour was emitted continually from Crater 2 during the month, while Crater 3 was quiet.
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.
