Crater 2 exhibited mild, continuous volcanic activity during May and very low activity during June. The May activity primarily consisted of the escape of moderately thick gray to brown ash clouds. Weak rumbling and roaring noises occasionally accompanied the emissions and fairly significant ash columns were forcefully ejected to 2 km height on 4, 9, 11, and 30 May. The ash clouds drifted NW, resulting in downwind ashfall. The June activity was summarized as the escape of mostly small to moderate amounts of vapor. Occasional ash-bearing (gray-brown) ash clouds were seen. In both months, there was no visible night glow, Crater 3 remained quiet and only occasionally released thin white vapor. The seismograph remained inoperative.

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.
