Short summary
We investigate an exhumed hydrothermal system in the Atacama Desert (Chile) to understand how earthquake swarms form. Wall rocks near fault veins experienced high-stress pulses, and fault veins underwent cyclic crack opening and shearing. These findings suggest ancient earthquake swarm activity, from dynamic crack propagation to repeated crack opening and shearing. This system represents a unique geological record of earthquake swarms, providing insights into their initiation and evolution.
