"Activity declined in early April . . . . Emissions from Crater 2 consisted of moderate to weak white-grey ash and vapour. An explosion on 3 April produced a dark ash column that rose ~500 m above the crater and resulted in ashfall on the NW side of the volcano. Steady weak red glow from the crater was observed on most nights. Following the first few days of stronger seismicity, when up to four explosion earthquakes/day were recorded, the seismicity declined and on most days no explosion events were recorded."
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.
