Alaid , Northern Kuriles, Russia : An intensive thermal anomaly was detected over Alaid volcano.

An intensive thermal anomaly was detected over Alaid volcano on February 20, 20:00 UTC (AVHRR 19) and on February 21, 00:56 UTC (NPP). Weak ash emission extended about 50 km to the east from the volcano was observed on satellite image (FY-3A) on February 20, 22:29 UTC.

Weak eruptive activity of the volcano continues. Ash explosions up to 19,700 ft (6 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

Alaid – the volcano-Island, the most northern in the Kurile archipelago, is situated at a distance 30 km north-west from Paramushir and 70 km south-west from Kamchatka. Alaid exposes high potential hazard to the aircrafts flying over Kamchatka and the Northern Kuriles because its eruptive clouds can rise to a height of 10-15 km above the crater and extend for hundreds of kilometers (up to 1500 km) and the duration of eruptions can exceed a few months. Last eruption was in 2012.
