US-India Satellite Captures Time-lapse Video of Volcanic Eruption
Like tendrils on a vine, lava spreads out from the northern crater of Krasheninnikov, a volcano pair on the Pacific coast of Russia’s Kamchatka Peninsula. On July 30, 2025, an 8.8-magnitude earthquake had struck in the nearby ocean, apparently jolting one of the two volcanoes awake. A few days later, for the first time in […] The post US-India Satellite Captures Time-lapse Video of Volcanic…
A volcanic eruption on Russia's Kamchatka Peninsula has been captured in a time-lapse video by the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite. The eruption began in July 2025 following a 8.8-magnitude earthquake, marking the first activity in nearly 500 years. Lava from the northern crater of the Krasheninnikov volcano pair has been spreading eastward, creating a fan-like flow.
The NISAR mission, which orbits 464 miles above the Earth, has been documenting the changes in the landscape. Twice every 12 days, NISAR has taken detailed radar snapshots of the volcano, providing valuable data for monitoring natural hazards. The L-band radar of NISAR, which can pass through tree canopies and is sensitive to the ground below, captured images of the lava field, showing it in a lighter shade compared to the surrounding snow or bare ground.
This time-lapse video, created from 17 frames captured between December 2025 and August 2026, demonstrates the satellite's precision and reliability in monitoring natural hazards.
