"Activity at Crater 2 dropped to its lowest level of the year, releasing mostly weak to moderate white vapour with occasional weak to moderate grey emissions (on 18, 19, 21, and 22 August). Crater 3 remained inactive throughout August, except on the 19th, when [weak] to moderate white vapour emissions were observed."
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.
