All times are local (unless otherwise noted)


"Activity remained at a low level in February. Crater 2 continued to produce weak-moderate emissions of white to pale grey vapour and ash, and at night a steady weak red glow was observed over the crater. Crater 3 emissions consisted of white vapour released at very low rates. Seismicity was also at a low level. On most days there were no volcanic earthquakes, but between 6 and 16 February up to 4 events/day were 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.
