"Activity returned to a low level in October . . . . Emissions from Crater 3 consisted mainly of occasional weak to moderate, white and grey, ash and vapour clouds. Deep, low, explosion and rumbling noises were heard on 6 and 7 October, respectively. Weak steady glow was observed on the 6th and the 9th. Activity at Crater 3 was somewhat subdued during the last week of October. Crater 2 released weak and occasionally moderate white and at times blue vapour throughout the month. Deep weak rumbling noises were heard between 16 and 28 October and steady weak glow was seen 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.
