'''Alaid,''' also called '''Atlasov''' due to its location or '''Araido''' in [Japanese](/source/Japanese_language), is a [volcano](/source/volcano) on [Atlasov Island](/source/Atlasov_Island) of the [Kuril Islands](/source/Kuril_Islands), [Russia](/source/Russia). It is the northernmost volcano of the islands, and one of the most [active](/source/Active_volcano). The height is disputed between {{convert|2285|m}}<ref name="OLYMPIC">{{cite web |title=The 'Olympic Rupture' of Alaid Volcano on Atlasov Island – Exclusive Drone Footage! |url=https://eugene.kaspersky.com/2019/08/20/the-olympic-rupture-of-alaid-volcano-on-atlasov-island-exclusive-drone-footage/ |website=eugene.kaspersky.com |access-date=24 November 2025}}</ref> to {{convert|2339|m}} tall.<ref name="NASA">{{cite web |last1=Stefanov |first1=William L. |title=Alaid Volcano, Kuril Islands, Russian Federation |url=https://www.earthobservatory.nasa.gov/images/78290/alaid-volcano-kuril-islands-russian-federation |website=www.earthobservatory.nasa.gov |publisher=[NASA](/source/NASA) |access-date=25 November 2025 |language=en |date=18 June 2012}}</ref> It is the highest peak of the Kuril Islands.<ref name="NASA" />

== Geographical setting ==
Alaid is located on [Atlasov Island](/source/Atlasov_Island), one of the Kuril Islands. These are part of the ring of [tectonic](/source/Tectonics) instability encircling the [Pacific Ocean](/source/Pacific_Ocean) referred to as the [Ring of Fire](/source/Pacific_Ring_of_Fire). The majority of these islands are [volcanic](/source/Volcanic_island), and that doesn't exclude Atlasov, which its main feature is the volcano.<ref name="BRITANNICA">{{cite web |title=Kuril Islands |url=https://www.britannica.com/place/Kuril-Islands |access-date=24 November 2025 |website=[Encyclopaedia Britannica](/source/Encyclopaedia_Britannica)}}</ref>

== Geology ==
It is formed mostly of [alkali basalt](/source/alkali_basalt)s, and minorly of [basaltic andesite](/source/basaltic_andesite).<ref name="MINDAT">{{cite web |title=Alaid volcano, Atlasov Island, Severo-Kurilsky District, Kuril Islands (Kurile Islands), Sakhalin Oblast, Russia |url=https://www.mindat.org/loc-410286.html |publisher=Mindat |access-date=25 November 2025}}</ref>  Many rare minerals are present on the mountain. Yellow [volborthite](/source/volborthite) and turquoise [atacamite](/source/atacamite) are present on the volcano.<ref name="MDPI">{{cite journal |last1=Zhitova |first1=Elena S. |last2=Nuzhdaev |first2=Anton A. |last3=Davydova |first3=Vesta O. |last4=Sheveleva |first4=Rezeda M. |last5=Zhegunov |first5=Pavel S. |last6=Kuznetsov |first6=Ruslan A. |last7=Kutyrev |first7=Anton V. |last8=Khokhlova |first8=Maria A. |last9=Vlasenko |first9=Natalia S. |title=Calcareous Skarn-like Mineral Paragenesis from Unaltered Basalt of the Alaid Volcano (Kuril–Kamchatka Island Arc) |journal=Minerals |date=26 February 2025 |volume=15 |issue=3 |pages=237 |doi=10.3390/min15030237 |doi-access=free |url=https://www.mdpi.com/2075-163X/15/3/237 |access-date=25 November 2025}}</ref>

=== Eruptions ===
Alaid volcano is one of the most active volcanoes of the [Sakhalin Oblast](/source/Sakhalin_Oblast) as a whole. The most significant eruptions were the [1793](/source/1793_in_Russia) and the [2022](/source/2022_in_Russia) eruption.<ref name="OLYMPIC" /> Local records indicate that eruptions also happened in [1854](/source/1854_in_Russia), [1860](/source/1860_in_Russia), [1894](/source/1894_in_Russia), [1981](/source/1981_in_Russia), [1996](/source/1996_in_Russia), [2015](/source/2015_in_Russia)–[2016](/source/2016_in_Russia), and [2022](/source/2022_in_Russia).<ref name="MINDAT" /><ref name="NASA" /><ref name="VOLCANOLIVE" />

==== 2022 eruption ====
The 2022 volcanic eruption was one of the biggest and most significant of the history of the volcano. Local flights had to be cancelled due to this eruption. It also [increased](/source/Accretion_(geology)) the territory of the island by an unknown minor amount.<ref name="2022 ERUPTION">{{cite journal |last1=Degterev |first1=A. V. |last2=Chibisova |first2=M. V. |last3=Romanyuk |first3=F.

[Strombolian-vulcanian activity](/source/Strombolian_eruption) provoked two [lava flows](/source/lava_flows), that went onto the southern slope of Alaid. The [ash plume](/source/ash_plume)s mainly spread to the southeast with their height reaching 300–530&nbsp;km. The outflow of [lava](/source/lava) caused the formation of [lahar](/source/lahar)s that descended the southern slope of the volcano and reached the island's [coast](/source/coast).<ref name="2022 ERUPTION" />

=== Height ===
Alaid is the tallest mountain of the Kurils,<ref name="NASA" /> and its peak makes [Atlasov](/source/Atlasov_Island) the highest island of all of Russia.{{citation needed|date=January 2026}} Like most other mountains, the height of Alaid is disputed. Some sources state that the height is of {{convert|2285|m}};<ref name="OLYMPIC" /><ref name="MINDAT" /> others, like [NASA](/source/NASA), put it at {{convert|2339|m}}.<ref name="NASA" /><ref name="VOLCANOLIVE">{{cite web |title=Alaid Volcano, Kurile Islands, Russia - John Seach |url=http://volcanolive.com/alaid.html |website=volcanolive.com |access-date=25 November 2025}}</ref><ref name="PEAKBAGGER">{{cite web |title=Vulkan Alaid - Peakbagger.com |url=https://www.peakbagger.com/peak.aspx?pid=17657 |website=www.peakbagger.com |access-date=25 November 2025}}</ref>
