Kadovar

Stratovolcano · Papua New Guinea · 365m

A plume at Kadovar is dispersing to the E in this November 2019 Planet Labs satellite image monthly mosaic (N is at the top). The flanks of the roughly 1.4 x 1.6 km island have been stripped of vegetation due to lava dome formation and collapse at the summit, with recent eruptive activity producing ash plumes and pyroclastic flows. Activity has also recently occurred at the base of the SE flank.

Geological summary

The 2-km-wide island of Kadovar is the emergent summit of a Bismarck Sea stratovolcano of Holocene age. It is part of the Schouten Islands, and lies off the coast of New Guinea, about 25 km N of the mouth of the Sepik River. Prior to an eruption that began in 2018, a lava dome formed the high point of the andesitic volcano, filling an arcuate landslide scarp open to the south; submarine debris-avalanche deposits occur in that direction. Thick lava flows with columnar jointing forms low cliffs along the coast. The youthful island lacks fringing or offshore reefs. A period of heightened thermal phenomena took place in 1976. An eruption began in January 2018 that included lava effusion from vents at the summit and at the E coast.

From Wikipedia

Kadovar is a volcanic island in Papua New Guinea northeast of the much larger island of New Guinea. The volcano erupted in January 2018 and the eruption is ongoing as of 2023, although the activity level is generally considered to be low. There were some heightened thermal phenomena in 1976.
