Susana Vilanova at 90 Segundos de Ciência: Unravel the earthquakes of the past to assess the seismic risk

Susana Vilanova presented the study concerning the Lower Tagus Valley Fault Zone. In this project CERENA researchers have identified and mapped the fault of the Lower Tagus Valley using high and very high resolution digital terrain models based on remote sensing methodologies. Geochronological dating indicates that this geological structure was most likely responsible for the great Lisbon earthquake of 1531, and that at least four earthquakes of high magnitude will have occurred during the prehistoric period, since 6000 BC. This information is fundamental for seismic risk analysis. This information is fundamental for seismic risk assessment.
