Activity was generally at a low level in April with weak white vapour emission from Crater 2 and little or no activity at Crater 3. However, a strong explosion occurred at Crater 2 on 12 April, propelling an ash cloud to ~3 km above the volcano. The explosion was heard  km away where fine ashfall was noted. Preliminary examination of the ash indicated that it contained little or no fresh material.
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 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.
