Alaid is the tallest and northernmost volcano in the Kurile Islands. Also called Atlasov as the island it forms, the symmetrical stratovolcano rises 3000 m from the sea floor and forms a small island. It has a 1.5-km-wide summit crater breached to the south. It is one of the Kuriles'most active volcanoes. Large explosive eruptions occurred in 1790 and 1981, and were among the largest in the Kuriles in historic times.

Background
Numerous flank cones dot the lower flanks of the basaltic to basaltic-andesite Alaid volcano, particularly on the NW and SE sides, including an offshore cone formed during the 1933-34 eruption.Alaid has 2 types of eruptions: summit activity from the central crater as well as lateral eruptions. The eruptions from the central crater tend to be more explosive and are more dangerous. The largest eruptions from the central crater were in February 1793, June 1854, July 1860, 1894, and April 1981.
The principal volcanic hazard from Alaid are ash plumes dangerous for aircraft (many routes from N-America to Asia pass nearby).

Remark:
Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.

2003 tremors
Seismic tremor began at Alaid volcano on 31 October and continued until November. The tremor was believed to be caused by strong winds, not caused by volcanic activity. (Source: GVP monthly roports)

1997 eruption
In August 1997, a thermal hotspot was visible on satellite images of the volcano indicating eruptive activity. Ashfall occurred on SW Kamchatka.

1996 eruption
Seismic activity increased in December 1996. Satellite images showed a plume reaching a height of 6 km above the volcano. A large snow storm prevented any visual observations. (GVP monthly reports)

1986 collapse of cone in summit crater
Aerial observations on 25 May 1986 revealed that the summit crater's 1981 cone (250 m high and 600 m across at its base) had been almost entirely destroyed recently. At its place there were 2 collapse craters, the larger of which measured 300 m across and ca. 100 m deep.

1972 lateral and submarine eruption
A lateral, partly submarine eruption began at Alaid volcano in June 1972. An eruptive fissure extended from the NW base of the volcano to the sea. The water-magma interaction produced powerful explosions and ash plumes 8 km high.

Alaid Volcano FAQ
+When was the last eruption of Alaid volcano?
The last confirmed eruption of Alaid occurred in 2022.
+How often does Alaid volcano erupt?
Since 1790, Alaid volcano has had at least 15 historically documented eruptions. This means that it erupts on average every 15.7 years.
Many eruptions of Alaid have lasted more than one year. In total, the volcano has been in eruption during 19 out of 235 years until now. In other words, Alaid has been active at least one in 12.4 years on average. Note that this value is likely an underestimate, because the known history of eruptions from Alaid is likely incomplete, especially further back in time.
+How active is Alaid volcano at present?
Alaid volcano is infrequently active: Since 1900, it has had 12 eruptions, and been active during 12 years out of 126 as of now. This means, Alaid has been in eruption one in 10.5 years on average. The last eruption was in 2022 and ended 3 years ago.
+When was the largest eruption of Alaid volcano?
The largest eruption of Alaid volcano in historic times occurred in 1981. It ranks as a sub-plinian eruption with a magnitude 4 on the VEI (Volcanic Explosivity Index) scale.
