50.861°N, 155.565°E; summit elev. 2285 m

All times are local (unless otherwise noted)

On 3 December, satellite imagery indicated a plume rising to a height of 5-6 km from Alaid. The nearest seismic station, located in the town of Severo-Kurilsk (Paramushir Island), 25 km E of Alaid, recorded the beginning of local seismic activity at about the same time as the satellite report. A large snow storm obscured the volcano, and no visual reports of eruptive activity were received from the coast guard, ships, or aircraft in the area.

Geologic Background. The highest and northernmost volcano of the Kuril Islands, 2285-m-high Alaid is a symmetrical stratovolcano when viewed from the north, but has a 1.5-km-wide summit crater that is breached widely to the south. Alaid is the northernmost of a chain of volcanoes constructed west of the main Kuril archipelago. Numerous pyroclastic cones dot the lower flanks of this basaltic to basaltic-andesite volcano, particularly on the NW and SE sides, including an offshore cone formed during the 1933-34 eruption. Strong explosive eruptions have occurred from the summit crater beginning in the 18th century. Reports of eruptions in 1770, 1789, 1821, 1829, 1843, 1848, and 1858 were considered incorrect by Gorshkov (1970). Explosive eruptions in 1790 and 1981 were among the largest in the Kuril Islands during historical time.
