[Volcanism] continued during November at more moderate levels. Activity from Crater 2 consisted of moderate Vulcanian explosions accompanied by loud detonations. Some of these ash-laden emissions rose several hundred metres above the crater rim producing light ashfalls on the N and NW sides of the volcano. Steady weak red glow from Crater 2 was observed on 15, 21, 22, and 23 November. In the first week of November, Crater 3 activity consisted of weak-to-moderate Strombolian explosions and weak lava effusion. After the 7th, the activity changed to Vulcanian explosions only, accompanied by weak-to-loud detonations. Seismicity showed a moderate level of activity with 1-46 recorded explosion events/day."
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.
