Satellite imagery reveals continued volcanic activity and melting snow deposits at Shivelyuch volcano.
📍 Kamchatka Peninsula, Russia
The remote Shivelyuch volcano, the most northerly active volcano on the Kamchatka Peninsula, continues to display significant geological activity, as captured in a recent image acquired by the Landsat 9 satellite on April 23, 2026. The image shows fresh signs of the volcano’s unrest, with snowmelt revealing dark deposits of ash and soil from recent thermal anomalies, hot avalanches, and debris flows within its horseshoe-shaped caldera. Scientists are monitoring a multi-lobed lava dome growing within the caldera, a result of ongoing, slow extrusion of viscous lava, mirroring the shape of toothpaste being squeezed from a tube.
This ongoing activity is typical of Shivelyuch, a volcano known for its explosive bursts of ash and pyroclastic flows triggered by the collapse of lava domes. Geologists, like Alina Shevchenko from the GFZ Helmholtz Centre for Geosciences, describe these events as “block-and-ash flows,” containing cooled volcanic rock and ash, which often create insulating deposits that retain heat for extended periods. These deposits have been observed to melt the surrounding snow, creating stark contrasts in the landscape visible in the satellite imagery.
Recent monitoring by the Kamchatka Volcanic Eruption Response Team (KVERT) indicates continued explosive-extrusive eruptions accompanied by powerful gas-steam activity. A particularly destructive event in April 2023 – a large eruption and flank collapse – resulted in massive pyroclastic flows traveling tens of kilometers and leaving long-lasting deposits and flow channels near the volcano's base, highlighting the ongoing potential for hazardous activity at this dynamic location.
