During July, Crater 2 continued its low-level eruptive activity and Crater 3 remained quiet. Crater 2 emitted gray to brown ash clouds, which rose several hundred meters above the crater. The ash clouds were blown to the NW and produced light ashfall. The emissions were accompanied by rumbling and explosion sounds. On most nights in July, variable glows were observed around the crater. Small incandescent lava fragments were ejected on 12 July.
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.
