The capital city of Lisbon and the Lower Tagus Valley region of central Portugal mainland are located in the Eurasian plate about 350 Km from the approximately E-W oriented Eurasia-Africa plate boundary. It is characterized by low slip-rates (<0.4 mm/year) and a moderate seismicity, occasionally shaken by some important historical earthquakes causing significant damages and economical losses. The most well know...

Apresenta-se um mapa tectónico das falhas activas e um mapa geomorfologico entre a Crista Tore-Madeira e o estreito de Gibraltar. Classificam-se as falhas do ponto de vista geométrico, cinemático e cronológico. Apresentam-se resultados de modelação numérica e análoga para a interferência de falhas de desligamento dextrógiro (próximas de WNW-ESE/90º) e cavalgamento (NE-SW/SE) e ainda para a interferência dest...
