Short summary
We investigated prehistoric earthquakes produced by the Galera Fault (southern Spain) over the last 24 000 years. From this analysis, we deduced the basic parameters that allow for the characterization of the seismic hazard of this fault. Furthermore, we discuss how the Galera Fault is prone to producing seismic crises. We also propose that one of these crises could have been responsible for the abandonment of Bronze Age human settlements located near the fault.
