"Observations were conducted during 1-17 and 23-27 April. The level of activity was slightly lower than in March. Emissions from Crater 2 consisted mainly of thin-to-moderate white-grey vapour-and-ash clouds. Explosion noises were heard on 4, 5, and 17 April, and weak rumbling noises were heard during 23-27 April. The explosion on 4 April produced a thick ash column that rose a few hundred metres above the crater and resulted in fine ashfall on the NW side of the volcano. Steady weak red glow was observed on 23-24 April. Crater 3 released emissions of thin white vapour with occasional low ash content. Seismic activity was at a low level."
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.
