Recent marine lithofacies in Cadiz Bay (SW Spain)

The radiocarbon age indicates that these high energy events happened between 898 ± 120 BC and 849 ± 121 AD, some of which coincide with several historically documented tsunamis affecting the Cadiz coast. This data indicates that the period from 849 AD to 1200 AD was a time of intense seismic and tsunamigenic activity.
