Abstract

In this work we offer the parameters of the seismogenic sources for the AD 1936 Tavernes and AD 1748 Estubeny historical events. Comparing with the spatial distribution of ESI-07Intensities, ShakeMap models in terms of PGA with different features of the seismogenic source (epicentral location, Mw, orientation of the source) have been obtained. After iteration, the chosen seismogenic source was that with the best fit between the PGA ranges of intensity used by the USGS and with ESI-intensity evaluations of the zone. For the Tavernes event results point to a NW-SE (Mw 7.0) normal fault and for the Estubeny to a reverse fault ENE-WSW oriented and Mw 6.5. Analyses of the main structures and its features as well as the reconstructions of the focal mechanisms in the study area are quite compatible with obtained data.
