The area under examination has been studied in terms of the lithosphere elastic properties since 1980 (Panza et al., 1980; Calcagnile and Panza, 1981; Calcagnile et al., 1982; Babuska et al., 1984; Locardi, 1988). The origin of the Ionian lithosphere is still under debate.
The contribution of the research unit of the Department of Earth Sciences of Trieste University will consist in the delineation of the main structures of lithosphere-asthenosphere system, in the refinement of the existing models through new experimental evidences, and in the use of these informations for seismicity and present-day stress field regionalization. The final goal of the project is to contribute to the formulation of a comprehensive model that reflects known relationships among geology,
geodynamics and geochemistry.
The obtained knowledge on the Earth structure including available results in the literature, will be integrated to refine the related part of EurID digital model (Du et al., 1998). The Adriatic plate seismicity and stress field will be studied through the use of extended sources, with advanced methodologies of waveform inversion (Das e Suhadolc, 1996; Das et al., 1996; Sarao' et al., 1998) with the double purpose: (1) to determine the stress field using directly all polarities and not single mechanisms (Lander et al., 1993); (2) to underline the differences in the thermal regime of the various seismogenic zones trough creepex analysis (Prozorov e Hundson, 1974).
