"Activity . . . was at a lower level during October than in previous months. Emissions from both craters consisted of weak-to-moderate white-to-grey vapour-and-ash clouds. Blue vapour was occasionally released from both craters during the latter part of the month. There was no glow observed throughout the month. Noises were heard from Crater 2 on the 31st. Seismicity remained low throughout the month."
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.
