Preliminary crustal model from seismological observations at the Messina Straits network

Abstract

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