In the present paper seismometrical data have been worked
out regarding the Norcia earthquake during the 19 September - 31 December
1979 period. 479 seismic events have been identified, with a good
analytical resolvance for the majority of same. With reference to main
shock, as well as for 30 other after shocks the focal mechanisms were
defined using different data assemblies. A contemporary inversion of
hypocentral parameters of the velocity model was made on a data selected
sample. The temporal variation of after shocks was also studied during
the considered period
