NISAR satellite captures time-lapse video of Krasheninnikov volcano eruption in Russia
The NASA-ISRO Synthetic Aperture Radar mission recorded a time-lapse video of the Krasheninnikov volcano erupting on Kamchatka Peninsula, Russia, following an earthquake in July 2025.
Satellite monitoring begins after quake
An 8.8-magnitude earthquake struck the nearby ocean on July 30, 2025. This event apparently woke one of the volcano pair and caused an eruption for the first time in nearly five centuries. The NISAR satellite finished its post-launch checks and became operational shortly after this date.
Radar images show lava flow
Researchers sequenced 17 radar frames captured between late December and mid-August to create the animation. The footage shows lava filling a smaller inner caldera before overflowing into a wider crater. Molten rock then widened into a fan that flows steadily eastward from the northern crater.
Data supports hazard monitoring
The satellite passes over the site twice every 12 days to return detailed snapshots. These observations allow scientists to track landscape changes for both research and emergency response purposes. The animation highlights how such data can monitor natural hazard development.
