"Activity remained at a low level in November . . . . Crater 3 emitted mainly weak to moderate white-grey ash and vapour clouds. However, stronger emissions on 12 and 25 November produced eruption columns ~200 m high and ashfalls ~10 km downwind. Weak deep explosions from Crater 3 were heard on 28 and 29 November. Emissions from Crater 2 consisted mainly of weak to moderate white and grey vapour and ash, and rarely, blue vapour. Steady weak glow was observed throughout the month. The only sound from this crater during November was a deep loud explosion on 28 November and rumbling noises on the 29th and 30th. Seismic activity was at a moderate level."

Geological Summary. 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 E flank of the extinct Talawe volcano in the Cape Gloucester area of NW New Britain. A rectangular, 2.5-km-long crater is breached widely to the SE; Langila was constructed NE of the breached crater of Talawe. An extensive lava field reaches the coast on the N 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. The youngest and smallest crater (no. 3 crater) was formed in 1960 and has a diameter of 150 m.
