A joint US-India satellite mission has captured a time-lapse video documenting the eruption of Krasheninnikov, a volcano pair located on Russia’s Kamchatka Peninsula. The event marks the first time in nearly five centuries that the volcano has been active, with the NASA-ISRO Synthetic Aperture Radar (NISAR) mission tracking the significant changes to the landscape.

The eruption commenced just days after an 8.8-magnitude earthquake struck the nearby ocean on July 30, 2025, which is believed to have triggered the seismic activity. Since its awakening, the northern volcano of the Krasheninnikov pair has continuously discharged a steady, eastward-flowing field of molten rock and debris across the Pacific coast region.

From its orbital position approximately 464 miles (747 kilometres) above Earth, the NISAR satellite commenced its observations of Krasheninnikov on December 25, 2025. This initial capture occurred as the Earth-observing satellite concluded its post-launch checks and became fully operational, providing a crucial baseline for subsequent monitoring.

Satellite Monitoring Capabilities

The NISAR mission is designed for detailed environmental monitoring, returning to the same orbital spot every 12 days. During each cycle, the satellite conducts two passes – once travelling from south to north and again from north to south – to collect comprehensive radar snapshots of the Earth's surface. This consistent data collection methodology allows researchers to track minute changes over time.

Utilising 17 of these radar frames, captured between December 2025 and mid-August 2026, scientists have compiled a time-lapse video. The animation vividly illustrates the spread of lava, which appears brighter in the foreground compared to the surrounding terrain, as it fills a smaller, inner crater of the volcano. The imagery reveals the molten rock extending outwards in a pattern reminiscent of spreading tendrils, offering unprecedented insight into the dynamics of this historic eruption.
