Abstract

The application of the statistical analysis to a series of microshocks
originating in the Messina area allows to determine the level and the
type of interdeDer.den.ee between those events.
The investigation aims to identify an "occurrence model" compatible
with the series in question, and shows the inadequacy of the simple
Poisson process to describe the phenomenon observed; the series of events
in question can, instead, be represented as a succession of periods of
activity — conforming to a compound Poisson distribution — separated
by intervals of seismic inactivity of varying duration.
The results reported here seem very correlated with those from an
analysis of the spatial distribution of the activity; moreover, they are
of interest for comparison with the characteristics of other regions, and
constitute data that can be used for a more complete characterization
of the structures which originate the activity itself.
