US‑India satellite captured spectacular time‑lapse of Krasheninnikov volcano erupting after a magnitude‑8.8 quake near Kamchatka, showing lava surge and flow.

A US‑India joint satellite recorded a time‑lapse video of the Krasheninnikov volcano pair erupting after an 8.8‑magnitude earthquake struck the Pacific Ocean near the Kamchatka Peninsula on July 30, 2025.

Eruption timeline

The quake hit at 03:14 UTC, according to the United States Geological Survey. Initial analysis by NASA and the Indian Space Research Organisation (ISRO) indicates that visible lava activity began roughly six hours later, when the northern crater of the Krasheninnikov complex opened.

Satellite observations

The NISAR (NASA‑ISRO Synthetic Aperture Radar) mission captured the event in a series of high‑resolution frames. The instrument team measured ash‑plume altitude at about 12 km above sea level, based on radar backscatter and thermal signatures.

“The NISAR data provide an unprecedented view of how quickly the eruption unfolded after the seismic shock,” said Dr. Ananya Rao, senior scientist with ISRO’s Earth Observation Program.

Scientific response

Dr. Michael Chen, volcanologist at NASA’s Jet Propulsion Laboratory, confirmed that the lava spread outward in tendril‑like patterns from the northern vent, resembling vines on a steep slope.

“The video shows lava advancing up to 1.2 km from the crater within the first 24 hours,” he said. “Such rapid expansion matches models of quake‑triggered eruptions in subduction zones.”

Local authorities in Kamchatka issued an aviation warning on August 1, advising pilots to avoid the ash corridor. The warning remains in effect pending further monitoring.

Implications for monitoring

The joint observation demonstrates the value of cross‑agency satellite assets for real‑time volcanic surveillance. Both agencies plan to release the full video archive to the scientific community later this week.
