ResumoThe Sao Teotonio-Aljezur-Sinceira fault system extends NNE-SSW for 50 km, parallel andclose to the southwest Portuguese coast, presenting several small Cenozoic tectonic basins. Althoughseveral studies were carried out to recognize and evaluate the recent tectonic activity, estimated as slowrate with 0.017-0.032 mm a-1, a detailed seismotectonic study was never conducted. A thorough geomorphologicand tectonic study is necessary to understand the relationship between this fault system(on-shore faulting) and off-shore structures related to the nearby Azores-Gibraltar plate boundary zone,which generate important seismic activity, such as the 1755 Lisbon earthquake.
