"Moderate activity prevailed . . . throughout August. Activity at Crater 2 consisted of weak emissions of white and blue vapour with occasional rumbling sounds. From the 19th onward, the volume of gas and vapour emission increased, explosion sounds were heard intermittently, and a night glow was seen above the crater. Activity at Crater 3 was limited to occasional emission of white to grey vapour clouds. Seismicity remained low throughout the month, with only a few explosion shocks recorded daily."
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.
