"A steady decrease in volcanic activity was observed at Crater 2 during July, while Crater 3 remained inactive. Emissions from Crater 2 were mostly white but occasionally grey (on 7, 16, 18, 20, 21, 26, and 27 July), and weak to moderate in volume. Occasional low rumbling sounds were heard from the 1st to the 20th and on the 28th. One loud explosion on the 16th accompanied the ejection of thick brownish-grey ash, forming a column that rose 1200 m above the crater. Night glow around the crater mouth was visible only on the 1st and 5th."

Geological Summary. 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 E flank of the extinct Talawe volcano in the Cape Gloucester area of NW New Britain. A rectangular, 2.5-km-long crater is breached widely to the SE; Langila was constructed NE of the breached crater of Talawe. An extensive lava field reaches the coast on the N 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. The youngest and smallest crater (no. 3 crater) was formed in 1960 and has a diameter of 150 m.
