"Satellite Images Capture Massive Smoke River from Russia's Tallest Volcano Eruption"

Russia's tallest volcano, Klyuchevskoy, erupted violently, spewing a 1,000-mile-long cloud of dust and ash into the air. The eruption reached a maximum height of 7.5 miles above Earth's surface and prompted the grounding of planes and evacuation of schools due to increased air pollution. Satellite images captured the massive eruption plume, which stretched across Russia and the Pacific Ocean. While significant, the eruption plume is still smaller than some of the largest ever recorded. Unlike previous eruptions, Klyuchevskoy's latest eruption is not expected to have a significant impact on the ozone layer.
