According to KVERT, observers on both Paramushir (SE) and Shumshu islands reported weak gas-and-steam plumes containing small amounts of ash from Alaid during 5, 11, 16-17, 23, and 27-28 October 2012. Photos taken on 27 October showed ash deposits on the cone and a small cinder cone growing in the crater. The cone was again covered by ash on 8 November. Seismicity increased on 16 November and remained elevated until 6 December, when it decreased until 10 December. Technical problems prevented seismic recordings after that. Satellite imagery showed a weak thermal anomaly on the volcano until 12 December. On 8 January 2013 the Aviation Color Code was lowered to Green.

17 October-23 October 2012

According to KVERT, observers on Paramushir Island (SE) reported weak gas-and-steam activity from Alaid during 11 and 16-17 October. A thermal anomaly on the volcano was detected in satellite imagery during 12 and 14-17 October. Cloud cover prevented observations during 19-22 October. Observers on Shumshu Island (50 km E) reported that an ash plume rose 700 m above the crater on 23 October and a thermal anomaly was detected in satellite imagery. The Aviation Color Code remained at Yellow.

10 October-16 October 2012

According to KVERT, observers on Paramushir Island reported that on 5 October a large gas-and-steam plume from Alaid rose 200 m above the crater. A thermal anomaly on the volcano was detected in satellite imagery for 7.5 hours the next day. The increased activity prompted KVERT to raise the Aviation Color Code to Yellow on 7 October. Satellite imagery detected a thermal anomaly on 15 October.

26 May-1 June 2010

KVERT reported that on 23 May a gas-and-steam plume from Alaid was seen in satellite imagery drifting 11 km ESE. No other signs of possible increasing activity were seen in imagery or noted by observers on Paramushir Island during 21-28 May. KVERT lowered the Aviation Color Code to Green.

17 December-23 December 2003

During 12-19 December, KVERT reduced the Concern Color Code at Alaid from Yellow to Green. Seismicity had been slightly above background levels since 31 October, but KVERT seismologists concluded that it was not related to volcanic activity.

12 November-18 November 2003

During 7-14 November, seismicity was above background levels at Alaid. Spasmodic volcanic tremor occurred and a large number of weak local earthquakes were recorded. Clouds obscured satellite images of the volcano. Alaid remained at Concern Color Code Yellow.

29 October-4 November 2003

KVERT raised the Concern Color Code at Alaid from Green to Yellow on 4 November.

The highest and northernmost volcano of the Kuril Islands, 2339-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 and rises 3000 m from the floor of the Sea of Okhotsk. Numerous pyroclastic cones dot the lower flanks of basaltic to basaltic-andesite Alaid 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 at Alaid in 1790 and 1981 were among the largest in the Kuril Islands during historical time.
