Moderate explosive activity continued at Crater 2 during March, however, there was possibly a slight decline compared to last September. Intermittent Vulcanian explosions released ash clouds that rose several hundred meters above the crater. These explosions resulted in minor ashfalls to the volcano's SE. A weak but steady crater-glow was observed on a few nights. In accord with these observations, 6-30 daily explosion earthquakes registered at a station 4 km away. There was no visible activity from 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.
