"Low-level activity continued in December. Weak to moderate white emissions with occasional grey ash clouds were released from Crater 2. Weak rumbling noises were heard 28-31 December. A Vulcanian explosion on the 4th ejected an ash column that rose a few hundred metres and resulted in light ashfall to the SE. Crater 3 remained inactive throughout the month. Seismic activity remained at a low level with <10 events/day near the end of the month."

Geological Summary. 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 E flank of the extinct Talawe volcano in the Cape Gloucester area of NW New Britain. A rectangular, 2.5-km-long crater is breached widely to the SE; Langila was constructed NE of the breached crater of Talawe. An extensive lava field reaches the coast on the N 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. The youngest and smallest crater (no. 3 crater) was formed in 1960 and has a diameter of 150 m.
