"At 15:55 KST [3:55 GMT], explosions raised ash from Klyuchevskoy Volcano to 7.5 kilometers above sea level, with volcanic ash tail stretching 50 kilometers northeast of the volcano. Aviation color code: orange. The volcano’s activity is dangerous for local and international air travel," the statement from the Academy read.
This marks the second ash eruption from the volcano on Monday. The previous eruption, recorded several hours earlier, reached a height of 6.5 kilometers (3.7 miles).
On August 2, the regional branch of the Russian Emergencies Ministry reported ash emission from active Klyuchevskoy, Shiveluch, Karymsky, Bezymianny and Kambalny volcanoes with a height of six to 10 kilometers. Tourists and residents of Kamchatka were advised to avoid trips and hikes within a 10-kilometer radius of these volcanoes’ summits.
On July 30, a magnitude 8.8 earthquake struck off the coast of Russia's Kamchatka Peninsula, becoming the strongest in the region since 1952.
Klyuchevskoy Volcano is 4,850 meters (15,912 feet) above sea level and is located in the Ust-Kamchatsky district of Kamchatka. It last erupted in April 2025.
