Langila

Papua New Guinea

5.525°S, 148.42°E; summit elev. 1330 m

All times are local (unless otherwise noted)


During August, intermittent Vulcanian explosions interspersed with weaker ash-and-vapor emissions continued at Crater 2. Larger explosions rose several hundred meters above the crater rim and resulted in ashfalls on the downwind (N-NW) side of the volcano. Observers heard low detonations to deep rumblings; on 4, 5, and 17 August they saw weak, steady crater glow. No activity was seen from Crater 3. The 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.
