Abstract

Compressions and dilatations of all earthquakes occurring in the Italian peninsula have been revised in order to evaluate their focal mechanism and relate then to regional seismotectonic. Some fault plane solutions not reported in the available literature have been determined, including the 1915 Avezzano earthquake (M 1 = 6.8).

Focal mechanisms of 28 intermediate and deep Tyrrhenian earthquakes have also been revised. In this case predominant stresses are down dip compressions parallel to the dip of Benioff zone, and extensions axes orthogonal to this, oriented NW-SE.
