Critical considerations on the evaluation of macroseismic effects

Abstract


The definition of some of the standards used for evaluating local effects
and optimizing the relative macroseismic procedures are critically
considered, also from the different interpretative points of view to have
come out of the « Earthquake Catalogue » work group of the Italian Geodynamics
Projetc (PFG). Particular stress has been laid on the significance
and reliability of the main macroseismic parameters which depend
most directly on the investigative criteria used and on their ability to
characterize efficiently the interaction of earthquakes and environment.
Essentially, the analysis is of critical considerations and field-observations,
the fruit of macroseismic investigations carried out prevalently in
the Calabro-Peloritan Arc region. The seismic intensity, the use of macroseismic
scales, the investigatory criteria, the macroseismic field and its anomalies are the topics chosen for a study which — even if limited from
certain aspects — it is hoped will stimulate further thought and evaluations.
