Klyuchevskoy Erupts: Eurasia’s Tallest Active Volcano Spews Ash 40,000 Feet Into the Air

"Eruption activity escalated at the Klyuchevskoy volcano on Russia’s Kamchatka Peninsula in autumn 2023. When the MODIS (Moderate Resolution Imaging Spectroradiometer) sensor on NASA’s Aqua satellite acquired this image the ash plume from Klyuchevskoy (also Kliuchevskoi) rose as high as 40,000 feet above sea level. The plume extended 1,000 miles to the east-southeast, reported the Kamchatka Volcanic Eruption Response Team (KVERT)." SciTechDaily
