Abstract

Constraints in the way of deriving attenuation parameters for macroseismic intensity are applied to Italian data: statistical analyses on macroseismic data points, and fitting of models in a pseudo intensity versus distance plane increase the capability of reconstructing the actual damage distribution starting from earthquake catalogues. As a consequence, propagation property analyses as well as reliable seismic hazard studies can be performed. 1 Introduction Efespite the increase of strong-motions records, intensity attenuation versus epicentral distance is a cornerstone parameter in seismic hazard assessment, because its semi-empirical approach to the interaction between earthquakes and environment expands to historic times the observation period. Traditionally, the attenuation model
