Scientific paper

We compile a homogeneous and complete catalogue of the seismicity of the Italian region for 1975-1984, the period marking the transition from standard analogue seismometry to the new digital era.
The work is developed in three phases: (1) the creation of a uniform digital databank of all seismic station readings, unifying the database available at the Istituto Nazionale di Geofisica with the catalogue of the International Seismological Centre; (2) the preparation of numerical procedures for automatic association of arrival data and for hypocentre location, using arrivals from local, regional and teleseismic stations in a spherical geometry; (3) the introduction of lateral heterogeneity by calibrating regional travel-time curves and station corrections.
The first two phases have been completed, providing a new instrumental catalogue obtained using a spherical Earth model; the third phase is presented here in a preliminary stage.
