Aviation alart issued after eruption on Mount Klyuchevskoi.

The Kamtchatka Volcanic Eruption Response Team has issued a warning to aviation following an eruption on Mount Klyuchevskoi, a 4750, stratovolcano (cone-shaped volcano made up of successive layers of ash and lava), on the central Kamchatka Peninsula, at about 0.40 am local time on Wednesday 15 April 2020. The eruption produced an ash column that rose to a height of about 6000 meters above sealevel, and drifted about 65 km to the northeast. Smaller explosive eruptions continue on the volcano, which has been more-or-less constantly active since April 2019.

Mount Klyuchevskoi is part of the Klyuchevskoi Volcano Group in the Ust-Kamchatka (East Kamchatka) District, along with mounts Bezymianny and Kamen. The Kamchatka Peninsula lies on the eastern edge of the Okhotsk Plate, close to its margin with the Pacific and North American Plates. The Pacific Plate is being subducted along the margin, and as it does so it passes under the southern part of the Kamchatka Peninsula, and as it does so is partially melted by the friction and the heat of the Earth's interior. Some of the melted material then rises through the overlying Okhotsk Plate as magma and fuelling the volcanoes of southern Kamchatka.

Eruption on Mount Klyuchevskoi, Russian Far East.

The Kamtchatka Volcanic Eruption Response Team reported an eruption on Mount Klyuchevskoi, a 4750, stratovolcano (cone-shaped volcano made up of successive layers of ash and lava), on the central Kamchatka Peninsula, on Wednesday 3 January 2017, which produced a column of ash and steam that rose to 5.5 km above sealevel and drifted 92 km to the northeast. The volcano had been inactive for most of this year, but began to produce emissions on 2 December, and underwent  eruptions on the fifth, seventh, thirteenth, and twenty-first of the month.

Eruptive emissions from Mount Klyuchevskoi, Kamchatka Peninsula.

The Kamtchatka Volcanic Eruption Response Team recorded a series of small plumes of gas and steam emerging from Mount Klyuchevskoi, a 4750, stratovolcano (cone-shaped volcano made up of successive layers of ash and lava), on the central Kamchatka Peninsula, that forms the highest volcanic edifice anywhere on the Eurasian landmass. These emissions began on Saturday 2 December 2017, with a plume on Tuesday 5 December containing a significant amount of ash and drifting 170 km to the East. A warning has been issued to aviation, due to the hazards presented by volcanic ash, but there is little danger of the volcano causing problems for anyone on the ground due to its remote location.

Ash cloud from Russian volcano disrupts Alaskan air traffic.

Mount Kluchevskoi, an extremely active volcano on the Kamchatka Peninsula in the Russian Far East, underwent a particularly large eruption on Saturday 19 October 2013, producing a 10 000 m high ash column that drifted into Alaskan airspace over the weekend, leading to the cancellation of three flights from Alaskan airports, as well as delays to other services. The volcano produced a second major column on Sunday 20 October, this one around 8000 m high, and in addition has been ejecting incandescent material onto its slopes and producing lava flows on its flanks.

Kluchevskoi began erupting in August 2013, after a break of about ten months. The current series of eruptions has been going on for about a week, but started causing problems for Alaska at the weekend after a change in the wind direction. While Kluchevskoi presents an occasional problem for air traffic, it seldom harms people on the ground, though this is largely because nobody chooses to live near to it.

Eruption on Mount Klyuchevskoi.

Mount Klyuchevskoi, on the Kamchatka Peninsula, began erupting for the first time since October 2012 on the evening of Monday 26 August 2013, and continuing overnight. The volcano, which is the highest in Eurasia, produced small explosive eruptions through the night, throwing incandescent ash 200-300 m above the cone, visible from the village of Kozirevsk, according to the Skanex Research and Development Center. The volcano is in a remote location, and not an immediate threat to any human population, though a major eruption may cause disruption to aircraft and the tourist industry. There is also a danger that significant warming on the volcano may lead to ice and snow melting, with the danger of lahars (mud and debris flow caused by flash flooding mixed with volcanic material).
