"Following a strong eruption from Crater 2 in early May, activity declined sharply. From about 17 May occasional Vulcanian explosions took place at this crater, but usually the only emissions were white vapours and occasionally blue vapours in small volumes. Ashfalls were reported 10 km N of the crater at the beginning of June and on 8, 10, and 31 July.

"Crater 3 has shown declining activity since April when occasional explosions were seen. Weak white and blue emissions were seen until about mid-June, but since then the crater has been completely inactive except for weak white vapour emissions on 18 July. Seismic activity has remained low since mid-May."

Geological Summary. 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 E flank of the extinct Talawe volcano in the Cape Gloucester area of NW New Britain. A rectangular, 2.5-km-long crater is breached widely to the SE; Langila was constructed NE of the breached crater of Talawe. An extensive lava field reaches the coast on the N 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. The youngest and smallest crater (no. 3 crater) was formed in 1960 and has a diameter of 150 m.
