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).
