The Eastern Lower Tagus Valley Fault Zone in central Portugal : active faulting...
Canora, Carolina; Vilanova, Susana P.; Besana-Ostman, Glenda M.; Carvalho, João; Heleno, Sandra; Fonseca, João F. B. D.Active faulting in the Lower Tagus Valley, Central Portugal, poses a significant seismic hazard that is not well understood. Although the area has been affected by damaging earthquakes during historical times, only recently has definitive evidence of Quaternary surface faulting been found along the western side of the Tagus River. The location, geometry and kinematics of active faults along the eastern side of ...
Incorporating descriptive metadata into seismic source zone models for seismic-...
Vilanova, Susana P.; Nemser, Eliza S.; Besana-Ostman, Glenda M.; Bezzeghoud, Mourad; Borges, José Fernando; Silveira, António Brum da; Cabral, JoãoIn probabilistic seismic-hazard analysis (PSHA), seismic source zone (SSZ) models are widely used to account for the contribution to the hazard from earthquakes not directly correlated with geological structures. Notwithstanding the impact of SSZ models in PSHA, the theoretical framework underlying SSZ models and the criteria used to delineate the SSZs are seldom explicitly stated and suitably documented. In th...
