Based on analyses of satellite imagery and model data, the Darwin VAAC reported that on 7 June a minor ash emission from Langila rose to an altitude of 3.4 km (11,000 ft) a.s.l., slowly drifted SW, and detached form the summit. On 10 June a discrete event produced an ash plume that rose to 2.1 km (7,000 ft) a.s.l. and dissipated.

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.
