Although there was a lull in activity at mid-month, mild eruptive activity continued at Crater 2 in August. Moderate intensity, frequent ash emissions accompanied by rumbling and detonations took place from the beginning of the month until the 14th. In the period 15-20 August, the emissions were usually only white vapor. However, on the 16th there were two explosions. Frequent ash emissions resumed on the 21st with occasional stronger explosions. Throughout the month there were sightings at night of steady weak red glow above the crater. The Langila seismographs remained inoperative in August.
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.
