"Activity declined somewhat in February following the slight increase in late December-mid January. Weak-moderate emissions of white to pale-grey vapour and ash clouds were released from Crater 2 during most days of the month. Occasional weak rumbling noises were heard from Crater 2, and detonations were heard on the 14th and 22nd. Weak red glow from this crater was seen 6, 8, 9, 23, and 24 January. Crater 3 remained inactive throughout the month."
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.
