Earthquakes and tsunamis in Iberia: 50th years of the 1969 Saint Vincent earthquake (M=8.0)

UCM-Universidad Complutense de Madrid


On 28 February 1969 a large earthquake, located at the zone where the catastrophic 1755 Lisbon shock occurred, stroke the Iberian Peninsula and northern Morocco with important damage and casualties. The shock, located at SW of Saint Vincent Cape, was followed by a tsunami that affected the SW of the Iberian Peninsula and Atlantic coast of Morocco. The occurrence of large tsunamigenic earthquakes is a characteristic of the Ibero-Maghrebian region (other examples, besides that of 1755, are the 1790 Oran, Algeria or the 2003 Boumerdes shocks). In the last years there are new results derived from installation of permanent and temporary seismic stations in land and OBS, GPS geodetic and geological surveys, etc. The objective of the Workshop is the discussion of these new results in order to improve the knowledge of the occurrence of earthquakes and tsunamis at Ibero-Maghrebian region.
