Use of active fault data versus seismicity data in the evaluation of seismic hazard in the Granada basin (Southern Spain)

In this article we evaluate the seismic hazard in the Granada Basin (southern Spain), using for the first time the slip rate of known active faults. Our study, as an attempt to compute seismic hazard using active fault data in low to moderate seismicity regions, relies on a complete database of thes...
