All times are local (unless otherwise noted)

Monitoring of Langila resumed on 3 April following a lapse from 18 March to 2 April. Up to that time, activity at Crater 3 remained low and activity at Crater 2 continued at a moderate level. After the lapse in monitoring, Crater 2 continued to emit white vapors in low to moderate volumes. Gray ash clouds were occasionally emitted to several hundred meters above the crater. Occasional rumbling sounds and night time glows were normally associated with the ash emissions. Loud explosions were heard on 3 and 30 April. Ashfall NW of the volcano (in the Kilenge area) was reported on 11 April. Crater 3 released thin white vapor accompanied by wisps of blue vapor on 12, 14, 21, and 27 April. There were neither audible sounds nor night glows. Both seismographs remained inoperative during 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.
