"Activity was limited to weak or moderate emissions of white vapour from Crater 2, with a weak, steady, red glow at night from 25 March until 6 April, and 9-11 and 27-28 April. Occasional weak, deep rumbling noises were heard on 3 consecutive days 12-14 April. 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.
