We analyze the global and local uncertainties of ground motion-macroseismic intensity conversion equations and derive new probabilistic relationships between the macroseismic intensity and peak ground motion parameters (peak ground acceleration and peak ...

Macroseismic intensity versus epicentral distance: the case of Central Italy
Tectonophysics, 1991This paper refers to the attenuation of macroseismic intensity with epicentral distance. A new attenuation law is discussed, with particular reference to Italian conditions. The new formula shows a much better fit compared to traditional attenuation laws.

The anisotropic modelling of intensity distribution, affected by the construction of macroseismic planes, allows an analysis of the influence of each point of observed intensity on the analytical determination of epicenter and of the principal attenuation directions.

The macroseismic source parameters of earthquakes occurring within a sequence are strongly influenced by cumulative damage effects. When we deal with historical seismic sequences, in addition to the cumulative intensities, other intrinsic uncertainties

We recompute the coefficients of the intensity prediction equation (IPE) in Italy using the data of the DBMI15 version 2.0 (v.2.0) intensity database and the instrumental and combined (instrumental plus macroseismic) magnitudes reported by the CPTI15 v.

Problems in assessing macroseismic intensity from historical earthquake records
Terra Nova, 1993This paper tackles the problems connected with the use of macroseismic scales, with particular attention to MSK. Intensity estimates are in principle affected by uncertainties which are seldom quantified in practice. In the case of two localities (Scisciano and Orciano) damaged by two Italian earthquakes (1741, Fabriano and 1846, Orciano), which have a

Anisotropic attenuation of the macroseismic intensity
2019Macroseismic intensity is a measure of the size of an earthquake in terms of the damages caused to the anthropic and natural environment; it is an ordinal quantity expressed through the twelve degrees of the macroseismic scale. The set of intensity values recorded in the sites around the epicenter constitutes the macroseismic field of the event, that ...

A procedure is proposed for the reconfiguration of the macroseismic planes relative to earthquakes that, being characterized by a reduced number of points of observed intensity due to a lack of information, or having the epicenter very close to the coastline, are characterized by an incomplete distribution of observed intensity levels.

On an anisotropic attenuation law of the macroseismic intensity
Natural Hazards, 1995An anisotropic attenuation law of the macroseismic intensity has been deduced, congruent with an anisotropic modelling of macroseismic fields. The results, obtained by analysing a set of earthquakes in Eastern Sicily and Southern Calabria, show a greater adaptability to the observed data as compared with those deduced using isotropic attenuation laws ...
