Papua New Guinea

5.525°S, 148.42°E; summit elev. 1330 m

All times are local (unless otherwise noted)

During 2-20 November, eruptive activity at Langila's Crater 2 consisted of continuous emissions of pale gray ash plumes that rose to an altitude of 2.3 km (7,500 ft) a.s.l. and drifted N, NW, and W. On 6 November, two explosions produced ash plumes that rose to an altitude of 3.8 km (12,500 ft) a.s.l. Explosions of incandescent lava fragments were visible during 2-6 November and roaring noises were heard on 2-6, 12-16, and 20 November. Incandescence from the crater was visible intermittently during the reporting period.

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.
