During 1-2 November, eruptive activity at Langila's Crater 2 consisted of continuous emissions of pale gray ash plumes that rose to an altitude of 2.3 km (7,600 ft) a.s.l. and drifted N. On 1 November the plumes were accompanied by forceful white vapor plumes, and roaring noises were heard at regular intervals. Explosions of incandescent lava fragments were also visible.
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.
