"A low level of activity prevailed at Langila. Crater 2 released white vapour in moderate amount during the first half of the month, when a steady night glow could be seen (until the 17th). From the 20th onward, 1-3 explosion earthquakes were recorded daily while background seismicity remained at a low level. The amount of vapour released by Crater 2 decreased in the last week of May. Crater 3 remained inactive, apart from thin white vapour released by fumaroles in the crater."
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.
