Influence of attenuation models in seismic hazard evaluation for the north-eastern Sicily area

ABSTRACT

From the influence already revealed by attenuation models on the values of expected intensity for north-Eastern Sicity, the necessity arises to quantify the 'weigt' of these models and of their respective coefficients on the projection of intensity. A first evaluation is presented in this paper using the Sponheuer, Blake and Grandori models. A comparison of the expected intensity maps allows a first critical estimate, showing the greater adaptability of the Grandori model to describe the attenuation of intensity for the investigated area (AU)
