Both craters at Langila continued at a low activity level in May. Emissions from Crater 2 consisted of weak-to-moderate white-gray vapour and ash clouds. Occasional forceful ejections of thick, dark-grey ash columns accompanied by explosion noises were reported on the 2nd, 7th, 9th, 20th, 29th, and 31st. Fine ashfall was reported on the 2nd and 20th on the NW side of the volcano. A steady weak red glow was visible on the 5th. Crater 3 released thin white vapour with very low ash content accompanied by thin blue vapor. Seismic activity was at a low level at the beginning of the month. No seismic recording was achieved after the 3rd because of equipment failure."
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.
