Kadovar volcano eruptions

stratovolcano 365 m / 1,197 ft
Northeast of New Guinea, Papua New Guinea, -3.63°S / 144.63°E
Eruption list: 2018, 1700 (?)


1981 increase in thermal activity

The sea in an area off the NE was discolored with an orange stain during aerial inspections on 6 and 19 March 1981.

1976 increase in fumarolic activity

The volcano showed signs of a possible eruption in 1976: an increase in fumarolic activity and possible gas emission offshore were noted and all residents of Kadovar were evacuated to Blublup Island.
The first signs were noted May 1976 from an area at the S coast where possibly a small hydrothermal eruption or, more likely, a vigorous emission of gas bubbles occurred. The sea water in the area changed color and became a 100 m-long reddish zone of iron hydroxide in August.
Hot ground was first noticed up on the side of the lava dome around 16 September, and there was an increase in HCl and SO2 emissions which had a maximum temperature of 100 deg C.
In November, a second fumarole had developed near the hot ground discovered in September.
After November 1976 and throughout 1977, the activity stabililzed and later began to decline slowly starting in 1978. An observation in 1981 showed that the new hot areas had decreased in size and regrowth of vegetation has began to recover the area.

1700 possible eruption

A report of "smoke" at the volcano in 1700 could indicate an eruption.
