"Activity during February continued to be focused at Crater 2, at the moderately low level observed since December. Emissions consisted mainly of white-to-grey vapour-and-ash clouds in low or moderate volumes. Occasionally, an explosion produced a larger and darker cloud that rose a few hundred meters above the crater and produced fine ashfall SE of the volcano. Rumbling noises accompanying the emissions were heard intermittently throughout the month, and weak glow was seen on most clear nights. Activity at Crater 3 consisted essentially of fumarolic emission of thin white vapour. The seismograph was not in operation during February."

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.
