All times are local (unless otherwise noted)


"Low-level activity continued in September. Weak-moderate white emissions and occasional grey ash clouds were released from Crater 2. Explosion and rumbling sounds were heard on a number of days and weak crater glow was observed on the nights of the 5th and 14th. No eruptive activity took place at Crater 3. Seismic activity was low and only a few explosion earthquakes were recorded 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.
