Shiveluch Volcano Eruption: Ash Cloud Disrupts Air Traffic in Russia’s Far East
VLADIVOSTOK, March 12, 2026 – The erupting Shiveluch volcano on Russia’s Kamchatka Peninsula has sent a plume of ash approximately 8 kilometers (5 miles) above sea level, prompting an aviation warning. The eruption, which continues to be explosive-extrusive in nature, poses a potential risk to both local and international air traffic.
Eruption Details and Ash Cloud Trajectory
According to the Institute of Volcanology and Seismology, Far Eastern Branch of the Russian Academy of Sciences, the explosive activity lasted for 15 minutes, sending ash up to 8 km high. The resulting ash cloud is currently drifting eastward, towards the Aleutian Islands, a U.S.-owned archipelago .
An “orange” aviation warning has been issued, signifying a moderate level of risk to aircraft due to the potential for ash ingestion into engines. This warning is in line with international protocols for volcanic ash advisories.
Shiveluch Volcano: A History of Activity
Shiveluch is one of the largest and most active volcanoes on the Kamchatka Peninsula, part of the Pacific Ring of Fire . It has experienced at least 60 significant eruptions in the past 10,000 years . The volcano frequently experiences lava dome formations and hot avalanches, erupting approximately 0.015 km3 (0.0036 mi3) of magma annually .
The volcano is located 440 km (273 miles) from Petropavlovsk-Kamchatsky, Kamchatka’s largest city, and 45 km (28 miles) from the town of Klyuchi, which has a population of approximately 4,500 people . Recent eruptions have occurred over the past year and a half.
Geographic and Geological Context
Shiveluch, similarly known as Sheveluch (derived from the Itelmen word “suelich” meaning “smoking mountain”) , rises to a height of 3,283 meters (10,770 feet) . It is part of the Kuril–Kamchatka volcanic arc, a region known for its intense volcanic and seismic activity.
Potential Impacts and Monitoring
Volcanic ash emissions from Shiveluch can disrupt air travel between Asia and North America. Authorities are closely monitoring the situation and providing updates as the eruption continues. The potential for further eruptions and ash dispersal remains high.
