Developing a site-conditions map for seismic hazard Assessment in Portugal
Narciso, J.; Vilanova, S.; Lopes, I.; Oliveira, C. S.; Carvalho, J.; Pinto, C.; Borges, J. F.; Nemser, EThe evaluation of site effects on a broad scale is a critical issue for seismic hazard and risk assessment, land use planning and emergency planning. As characterization of site conditions based on the shear-wave velocity has become increasingly important, several methods have been proposed in the literature to estimate its average over the first thirty meters (Vs30) from more extensively available data. These ...
NEW SEISMIC SOURCE ZONE MODEL FOR PORTUGAL AND AZORES FOR USE IN SHARE: METHODO...
Vilanova, S.P.; Oliveira, C.S:; Brum da Silveira, A.; Madeira, J.; Nemser, E.; Fonseca, J.; Arvidsson, R.; Besana-Ostman, G:M:; Bezzeghoud, M.The development of seismogenic source models is one of the first steps in seismic hazard assessment. In seismic hazard terminology, seismic source zones (SSZ) are polygons (or volumes) that delineate areas with homogeneous characteristics of seismicity. The importance of using knowledge on geology, seismicity and tectonics in the definition of source zones has been recognized for a long time. However, the defin...
Compilation of parameterized seismogenic sources in Iberia for the SHARE Europe...
Nemser, E.S.; García-Mayordomo, J.; Cabral, J.; Fonseca, J.; Martínez-Díaz, J.J.; Alfaro García, P.; Àlvarez Gómez, J.A.; Atakan, K.Abstract: SHARE (Seismic Hazard Harmonization in Europe) is an EC-funded project (FP7) that aims to evaluate European seismic hazards using an integrated, standardized approach. In the context of SHARE, we are compiling a fully-parameterized active fault database for Iberia and the nearby offshore region. The principal goal of this initiative is for fault sources in the Iberian region to be represented in SHARE...
COMPILATION OF ACTIVE FAULT DATA IN PORTUGAL FOR USE IN SEISMIC HAZARD ANALYSIS
Nemser, E.S.; Cabral, J.; Terrinha, P.; Vilanova, S.; Besana-Ostman, G.M.; Bezzeghoud, M.; Borges, J.F.; Brum da Silveira, A.; Carvalho, J.; Dias, R.P.To estimate where future earthquakes are likely to occur, it is essential to combine information about past earthquakes with knowledge about the location and seismogenic properties of active faults. For this reason, robust probabilistic seismic hazard analysis (PSHA) integrates seismicity and active fault data. Existing seismic hazard assessments for Portugal rely exclusively on seismicity data and do not incor...
NEW SEISMIC SOURCE ZONE MODEL FOR PORTUGAL AND AZORES
Vilanova, S.P.; Oliveira, C.S.; Brum da Silveira, A.; Madeira, J.; Nemser, E.S.; Fonseca, J.; Arvidsson, R.; Besana-Ostman, G.M.; Bezzeghoud, M.The development of seismogenic source models is one of the first steps in seismic hazard assessment. In seismic hazard terminology, seismic source zones (SSZ) are polygons (or volumes) that delineate areas with homogeneous characteristics of seismicity. The importance of using knowledge on geology, seismicity and tectonics in the definition of source zones has been recognized for a long time [1]. However, the d...
