Geophysical conditions favoring precursory slip before major earthquakes
The Brief
- Laboratory experiments indicate that precursory slow slip before earthquakes is controlled by fault roughness and stress.
- On smooth faults, precursory slip is most pronounced at low stress.
- The study was published in Nature Communications on 14 November 2026 (doi:10.1038/s41467-026-79533-2).
Why it matters
The findings offer a laboratory-based explanation for when precursory slow slip appears before major earthquakes, which bears on how researchers interpret such signals in fault monitoring.
