Short summary
Many of the rapidly expanding cities around the world are located near active tectonic faults that have not produced an earthquake in recent memory. But these faults are generally small, and so most previous seismic-hazard analysis has focussed on large, more distant faults. In this paper we show that a moderate-size earthquake on a fault close to the city of Santiago in Chile has a greater impact on the city than a great earthquake on the tectonic boundary in the ocean, about a 100 km away.
