Story summary

Researchers at the University of California, Davis, report earthquake faults heal within hours after seismic events, acting like quick-set glue.
The findings were published November 19, 2025, in Science Advances, challenging understandings of fault behavior.
The team studied slow slip events in the Cascadia Subduction Zone, where faults can re-rupture quickly, implying rapid healing.
Experiments with high-pressure conditions showed quartz grains bond swiftly, suggesting cohesion may influence fault dynamics.
