"A moderate level of activity continued . . . in September. Activity at Crater 2 consisted of emission of white-to-grey vapour-and-ash clouds, occasionally with blue vapour. The emissions were accompanied by weak roaring noises. Weak night glow over the crater was seen 1-6 and 27 September. Emissions from Crater 3 were similar to those of Crater 2. Occasional weak explosions started on 6 September and continued until mid-September. No night glow was observed from the crater. Seismicity remained low throughout 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.
