Recenti risultati sulla velocità delle onile sismiche in Italia Centrale

R. Console, C. GASPARINI

Abstract


The seismic phenomena which happened near Cerreto di
Spoleto (December 1974) have been studied by data collected from the National
Network and the seismic mobile station. The latter had been placed in
the epicentral zone. As we could know good hypocentral parameters, we
determined travel times for Pg, Sg, Pn and Sn waves. For short travel
distances it lias been possible to point out strong azimuthal velocity anomalies,
connected with systematic errors in the epicentral determination. This
work allows us to foresee the possibility of improving (lie knowledge of the
crustal characteristics in our Country, as far as recording techniques will
improve.
