"Activity in May was similar to that in April. Intermittent weak-moderate ash emissions from Crater 2 were reported during the first 8 days of May. During the remainder of the month Crater 2 usually released white vapours at low rates. However, strong Vulcanian eruptions accompanied by loud detonations took place on 13, 25, and 28 May. These eruptions resulted in reportedly heavy ashfalls 10 km downwind. Weak emissions of white and blue vapours continued at Crater 3."
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.
