"Activity returned to a low level in November. Weak-moderate amounts of white vapour with occasional grey [ash] were emitted from Crater 2. Weak rumbling noises occasionally were heard on the 4th. Ashfall was observed on the 11th. Two Vulcanian explosions, on the 18th and 27th, were accompanied by ash columns that rose a few hundred meters. Crater 3 was inactive throughout the month. Seismicity remained low and only 9 explosion earthquakes were recorded."
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.
