All times are local (unless otherwise noted)


Moderately thick white vapor emissions continued at Crater 2 in April. Gray ash-laden clouds were seen rising to altitudes of 1-1.5 km on 7, 9-12, 16-17, and 22 April. On 25 April, ash clouds rose to an altitude of 2.5 km. A weak incandescent glow was seen on 22 and 28 April. Crater 3 released weak fumarolic vapors.

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.
