Russia’s Krasheninnikov Volcano, located in the remote Kamchatka Peninsula, erupted overnight in what scientists have identified as its first confirmed eruption in over six centuries.
Experts believe the event may have been triggered by the powerful earthquake that struck Russia’s Far East just days earlier.
According to the Kamchatka Volcanic Eruption Response Team, this marks the first historically verified eruption of the volcano since around 1463, with a possible margin of 40 years. Prior to this, Krasheninnikov had shown no known signs of volcanic activity for centuries.
The eruption, which occurred shortly after a major undersea earthquake on Wednesday, has drawn attention due to the potential connection between the two seismic events.
That quake, which was strong enough to prompt tsunami alerts in regions as far away as French Polynesia and Chile, also coincided with a fresh eruption of Klyuchevskoy, Kamchatka’s most active volcano.
Russia’s Ministry of Emergency Services confirmed that the eruption produced an ash plume rising up to 6,000 meters (approximately 3.7 miles), prompting aviation authorities to issue an orange alert — the second-highest on the scale — indicating possible danger to aircraft.
Officials noted that the ash cloud has drifted eastward over the Pacific Ocean and is not expected to impact any populated areas. Krasheninnikov Volcano itself stands at 1,856 meters above sea level.
While investigations into the exact cause of the eruption continue, volcanologists are closely monitoring seismic and volcanic activity in the region, which is part of the geologically volatile Pacific Ring of Fire.
