Overview

Lolo is a nearly symmetrical andesitic stratovolcano, ~3. 5 km in diameter, located N of Witori volcano along the N coast of New Britain near Cape Hoskins. It is of very late Pleistocene or Holocene age and overlaps the older Kapberg volcano to the west (Blake and McDougall, 1973).

Lava flows are prominent on its flanks, and a well-preserved crater 250 m wide and 60 m deep truncates the summit.

Volcanic Hazards & Risk Assessment

Regional Volcanic Activity
The Southwestern Pacific Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

About the Photo

Lolo rises to the N beyond lava flows producing gas plumes during the 2002 eruption of Pago. Lolo is located N of Pago volcano along the N coast of New Britain, near Cape Hoskins. It is of late Pleistocene or Holocene age and overlaps the older Kapberg volcano on its W side. Lolo contains a 250-m-wide and 60-m-deep crater.
