During June, white-gray or brown ash and vapor clouds emitted from Crater 2 rose to several hundred meters above the crater rim. Fine ash was mostly blown to the NW and occasionally to the SE and NE. Rumbling noises were heard throughout the month. During the first half of June, night glow was seen only on 5 June, but weak red glow was observed on most nights of the second half of the month. Weak to moderate projections of glowing lava fragments were observed on the nights of 17, 18, 19, and 21 June. Crater 3 remained quiet during June.
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.
