Mild, intermittent, eruptive activity continued at Crater 2 in January, while Crater 3 remained quiet. Crater 2 emitted continuous white vapor with occasional mild emissions of pale gray to brown ash clouds. During 1-4 January most ash emissions were accompanied by low rumbling and roaring sounds. The emissions rose to about 500 m above the summit before blowing to the SE. There was no seismic recording during 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.
