HeureMag. / DepthDistanceLocation
Lamonai is one of 3 volcanic centres of the Dawson Strait Group volcano. It is located on the SE end of Fergusson island inland from Sebutuia Bay. Lamonai volcano is a composite cone and has a steep-walled summit crater with strong thermal activity.
Rhyolitic lava flows are exposed on the NE side of the cone.

Introduction:

Dawson Strait Group volcano
from Smithsonian / GVP volcano information:
The Dawson Straits, located between eastern Fergusson and western Normanby Islands in the D'Entrecasteaux island group, contains a volcanic field with several volcanic centers that define a possible partly submerged caldera.
There have been no historical eruptions from this center, but morphology suggests an extremely young age for some lava flows, and the area displays vigorous thermal activity. The most prominent volcanic centers are Mounts Lamonai and Oiau, located about 10 km apart on the SW tip of Fergusson Island.
