All times are local (unless otherwise noted)


"For most of September the activity consisted of weak vapour emission accompanied by occasional small explosions. Only a very little ash was emitted. On 27 September a series of 10 loud explosions was accompanied by the emission of a dense ash cloud. A heavy ashfall occurred at Kilenge mission, 10 km NW of the volcano. No further details are yet available."

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.
