## In short

Decades of climate warming causally weaken rock stability through a multi-system chain — warming, permafrost thaw, slope failure — producing an event categorically unprecedented in the region's record.

## What they found (results)

A magnitude-6.5 earthquake on Jan Mayen island in March 2025 triggered a major rock avalanche because Arctic warming had already degraded permafrost and weakened the volcanic slope, an event with no precedent in the region's 40-year satellite record.

These researchers were not testing DSRP. The finding is theirs; the correspondence to DSRP is drawn by this site.
