What happened

US-India satellite captures time-lapse video of volcanic eruption Gaby Clark Scientific Editor Robert Egan Senior Editor Like tendrils on a vine, lava spreads out from the northern crater of Krasheninnikov, a volcano pair on the Pacific coast of Russia's…

Why it matters

On July 30, 2025, an 8.8-magnitude earthquake struck in the nearby ocean, apparently jolting one of the two volcanoes awake.

Common ground

A few days later, for the first time in nearly five centuries, Krasheninnikov started erupting.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
