All times are local (unless otherwise noted)


RVO reported that the emission of ash plumes from Langila's Crater 2 continued during 1-10 June and were occasionally forceful. Ash plumes rose to altitudes of 2.3-4.3 km (7,500-14,100 ft) a.s.l. and drifted NNW. Ashfall was reported at Kilenge Catholic Mission (about 10 km NW of the volcano) and surrounding areas. The emissions were continuous on 6, 7, and 10 June and accompanied by roaring noises. Booming noises were heard on 1 and 10 June. Crater 3 was quiet.

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.
