All times are local (unless otherwise noted)


Mild Vulcanian activity prevailed at Crater 2 in late May and this continued in June. Except for 5-9 June, throughout the rest of the month Crater 2 emitted moderate, pale to dark- gray ash clouds. Some rose ~2.0 km above the summit. Fine ash fell on the N and NW parts of the volcano on the 10, 12 and 18 June. Occasional low rumbling noises were heard on 13, 15, 16, 19, 20, 22, 28, and 30 June. No glow was observed. As has been typical, Crater 3 remained quiet. Seismographs remained inoperative during June.

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.
