"Monitoring was temporarily discontinued on 18 March. Until that time activity at Crater 2 was at a moderate level, similar to that observed in February, while Crater 3 showed a low level of activity. Emissions from Crater 2 were mostly white vapour, weak to moderate in volume. Occasionally grey ash clouds were emitted. Light ash fall took place around the crater. One loud explosion was heard on 8 March with weak explosions on the following two days and low rumbling sounds on the 16th. Steady weak night glow was observed on 16 and 17 March. Crater 3 released very thin to occasionally moderately thick white vapour. Thin blue vapour was observed on 1 and 7 March. There were no audible sounds and no night glows. Both seismographs remained inoperative 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.
