Seismogenic sources in the Lower Tagus Area using geophysical data

The Lisbon and Lower Tagus Valley area have suffered the effect of historical earthquakes that caused important damages and loss of lives. Some of these earthquake sources are local but they are still poorly known due to the difficulty in finding geological outcrops, together with low-slip rates and erosion/sedimentation processes that erase surface ruptures. Identification of seismogenic sources capable of pro...

Seismogenic sources in the Lower Tagus Area using geophysical data

Aplicação de dados geofísicos na caracterização de falhas com potencial sismogé...

O Vale Inferior do Tejo (VIT) tem sofrido os efeitos de sismos históricos. Algumas das fontes sismogénicas são conhecidas. Com vista a uma avaliação correcta das fontes sismogénicas em futuros estudos de perigosidade sísmica, integraram-se dados de reflexão sísmica, com dados de métodos potenciais e dados de epicentros relocalizados. As informações recolhidas a partir dos parâmetros das falhas irão ajudar à ...

Improving the seismic hazard evaluation of the Lisbon and Lower Tagus Valley area

The Lisbon and surrounding area of the Lower Tagus Valley has experienced in the past the effects of several moderate sized earthquakes that caused significant damage and destruction. They have been attributed to local sources, though in some cases the source remains to be located. The lack of outcrops in the flat lying Quaternary terrains, the low slip-rates of the area in connection with sedimentation and ero...

Looking for earthquake sources in the Lisbon area

The Lisbon and surrounding areas have suffered the effect of historical earthquakes that caused important damages and loss of lives. Some of these earthquake sources are local but they are still poorly known. The knowledge of these sources is important for seismic hazard studies. The use of geophysical methods in the area is required due to the difficulty in finding geological outcrops, together with low-slip r...
