Kadovar Island is a volcanic island in Papua New Guinea north-east of the much larger island of New Guinea. The only known eruption occurred on January 5, 2018. There was some heightened thermal phenomena in 1976.[2]

Geography

Kadovar is part of the Schouten Islands about 25 kilometres (15 mi) north of the mouth of the Sepik River. It is 1.5 km (0.9 mi) long and wide. Gewai village is near the crater rim. Authorities had thought around 700 people lived on the island, but it appeared closer to 2,000[3] during the re-settlement ordered before the eruption of 2018.[4]

History

The first recorded sighting by Europeans of Kadovar Island was by the Spanish navigator Iñigo Órtiz de Retes on 21 July 1545 when on board of the carrack San Juan trying to return from Tidore to New Spain.[5]

Smoke was reported which could have indicated an eruption in 1700. There were further indications of possible imminent eruptions in 1976 and 1981. The island was evacuated to Blup Blup Island in 1976.[6]

2018 eruption

The island was again evacuated by boats in early 2018 when the eruption was detected.[7] The Rabaul Volcanological Observatory described "mild vulcanian activity from a vent at the southeast base of the cumulodome," "a fissure may be opening just inside of the western wall of the vent’s breach, descending down to at least sea level."[8] According to the Darwin Volcanic Ash Advisory Center, the ash cloud formed a plume as high as 7,000 feet (2,100 m).[9]
