Distant Quake Triggered Slow Slip on Southern San Andreas

by Terri Cook 23 September 201929 September 2021

A high-resolution map of surface displacements indicates that the 2017 Chiapas earthquake caused substantial creep along a segment of the San Andreas Fault, located 3,000 kilometers away.

Tiny, Deep Quakes Increase on San Andreas as Tides Tug on Fault

by A. Coombs 26 July 20166 October 2021

When the gravity of the Sun and Moon causes Earth's crust to bulge every 2 weeks, slow-moving earthquakes proliferate in the lower reaches of the San Andreas, a new study finds.
