Kind: research · Impact: low

## In brief

- A research article in Science Advances (Volume 12, Issue 46, November 2026) examines nearshore subduction in Cascadia.
- The article's title states that upper plate structure controls nearshore subduction mechanics there.

## Why it matters

It examines how the overriding plate shapes shallow subduction processes off the Pacific Northwest, which bears on understanding that margin's tectonic behaviour.
