The Darwin VAAC reported that diffuse ash plumes at Langila were visible in satellite images at 1440 on 14 July rising to 1.8 km (6,000 ft) a.s.l. and drifting N. A thermal anomaly was also identified. Diffuse ash emissions continued to be identified in images through most of the next day. The ash emissions had dissipated by 1700 on 15 July; steam-and-gas emissions continued.

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.
