NASA Earth Observatory / Lauren Dauphin Shivelyuch (also called Shiveluch), the most northerly active volcano on the Kamchatka Peninsula, is one of the most active volcanoes in the world. On a near-daily basis, satellites detect new signs of activity within its horseshoe-shaped caldera, including thermal anomalies, hot avalanches and debris flows, and ash deposits that darken the surrounding landscape. The Landsat 9 satellite captured this image of the towering volcano—one of the largest and tallest on the peninsula—on April 23, 2026, a day when fresh activity left its mark on the snowy, late-spring landscape. A multi-lobed plug of viscous lava called a lava dome—appearing as a dark patch in the caldera—has been actively growing in recent months, according to reports from the Kamchatka Volcanic Eruption Response Team (KVERT). Dome-building lava is typically extruded slowly and piles up into lobed, sloped, or spine-like shapes akin to those that form when toothpaste is squeezed from a tube. The caldera contains a growing lava dome and signs of block-and-ash flows in channels radiating outward in this detailed image, acquired April 23, 2026, by the OLI (Operational Land Imager) on Landsat 9.
