Abstract


Starting from a general tectonic description of the Strait of Messina,
what follows is an explanation of the criteria adopted in choosing
sites for seismic stations of the Straits network.
The main lithological and mechanical characteristics of the terrains
where the stations are been located, together with the equipment used,
are mentioned, are looked at in relation to the positions of the main
centres of seismic activity both actual and in recent past, and to the
microseismic energy threshold.
A number of observations regarding the seismic crisis in the Gulf
of Patti (1978) are analized, with the aim of suggesting a crustal model
compatible with the area of the Messina Straits.
