"Activity was at a low level during November with occasional reports of grey ash clouds from Crater 2. A column of dark cloud was reported rising to about 200-300 m above the summit on the 30th. Two audible explosions (heard at the observation post, 10 km NW of the crater) were reported on the 17th and 30th. Crater 3 remained inactive throughout the month. Seismic activity remained at a low level throughout the month with only 2 explosion shocks recorded, on the 17th and the 30th."
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.
