"The first 3 months of 1981 have shown a steady decline of eruptive activity. Occasional brown ash-laden emissions from Crater 2 were observed in January, but in February and March emissions from Crater 2 were white and apparently of declining volume. Crater 3 released blue and white vapours in January and February; in March only small volumes of white vapour were emitted. The last time glow was observed was on 21 January from Crater 2. Seismic activity from Langila was at a low level January-March. Small tremor-like signals continued to be recorded."
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.
