The NASA-ISRO NISAR satellite has captured a time-lapse of the Krasheninnikov volcano pair erupting on Russia’s Kamchatka Peninsula — the volcano’s first eruption in nearly five centuries. NASA’s Jet Propulsion Laboratory published the video on September 24, 2026.

The volcano had been quiet since about 1550 before reawakening days after an 8.8-magnitude offshore earthquake on July 30, 2025. NISAR’s 17 radar frames run from December 25, 2025, taken during post-launch checks, through mid-August 2026, with revisits twice every 12 days from an altitude of 747 km.

The imagery shows lava filling an inner caldera, overflowing into a wider crater, and then widening into a fan-shaped eastward flow, each pixel covering about 10 metres. NISAR’s radar can see through clouds and darkness, orbits Earth 14 times a day, and covers about 1,300 active volcanoes above sea level.

The joint NASA-ISRO Synthetic Aperture Radar mission carries two radar instruments, one built by NASA JPL and one by ISRO. The time-lapse demonstrates the satellite’s ability to track natural hazards over time in areas that ground sensors rarely reach.
