"A generally low level of activity continued during the first half of July. Crater 2 produced occasional weak emissions of pale-grey ash and vapour, sometimes accompanied by weak explosions. From about 19 July, more sustained explosive activity occurred. Light ashfalls were reported ~10 km from the crater on 20 and 21 July. Weak red glow from the crater was seen on the night of the 21st. Only a few explosions were large enough to be recorded at the seismic station . . . ."
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.
