Critical considerations on the evaluation of macroseismic effects

Abstract

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