- VolcanoKadovar volcano forms the tiny 2 km wide Kadovar Island, one of the Schouten Islands. It is located 25 km north of the mouth of the Sepik River on New Guinea. The island is the submerged peak of a stratovolcano at the western end of the 1000 km long Bismarck volcanic arc. Kadovar contains a 1 km wide breached crater, and the village of Gewai is perched on the crater rim. There are no certain eruptions in historic time, but an increase in thermal activity occurred in 1976.
Volcano type stratovolcano dormant Location Summit elevation 365 m / 1,197 ft Kadovar volcano eruptions 1700 (?) Typical eruption style explosiveA landslide occurred in the past, removing part of the south slope and leaving an horse-show shaped car on the south side. The corresponding submarine debris avalanche deposits have been identified. A lava 365-m-high lava dome has partly filled the depression and forms the highest point of the andesitic volcano.
The volcano has produced thick lava flows with prismatic lava formations visible at low cliffs on the coast.
The volcano is too young for reefs to have formed around the island.
