In 2025, a magnitude-8.8 earthquake ruptured Kamchatka; scientists later used older GPS motion data to map a major locked zone that aligned with the rupture and smaller patches near its starting point
- Image: Serget Ponomarev/NYTWhen a magnitude 8.8 earthquake ruptured a fault offshore from Russia's Kamchatka Peninsula in 2025, it sent tsunami waves across the Pacific Ocean.
- Now researchers have shown that clues to where it would strike may have been sitting in ground-motion measurements collected years earlier.
- By reanalysing older satellite positioning records, a new study maps a major locked zone on the plate boundary that lines up with the rupture, along with smaller patches near the point where it began.
