An eruption began in Papua New Guinea, on the island-volcano Kadovar; it is the emerged summit of a Holocene stratovolcano located 25 km north of the mouth of the Sepik River. A lava dome caps the andesitic volcano and thickprismatic lava flows form coastal cliffs.
The date of its last eruption is unknown; only fading of the sea was observed in March 1981 in the northeast. Another episode took place in 1976-77 (GVP)
Two dinghies were sent to help evacuate the small population established on the edges of the crater.
