Low-level activity continued during February. Emissions consisted of weak white vapors from Crater 2 for most of the month. Weak explosion sounds were heard on 8 and 21 February, then more frequently between the 25th and 27th. Weak, deep, roaring noises were heard starting on the 13th and a weak night glow was observed 27-28 February. Crater 3 was inactive. Microseismicity remained at a very low, non-eruptive level.
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.
