This website publishes earthquake parameters provided in quasi real-time by the Italian earthquake surveillance service, and hypocenter parameters routinely revised by the analysts of the Istituto Nazionale di Geofisica e Vulcanologia (Centro Nazionale Terremoti) and published in the Italian Seismic Bulletin. Raw data or phase readings are produced by the Italian National Seismic Network, or by other local, regional and national networks belonging to other Italian or foreign institutions.
We publish here the parameters of all the seismic stations that gave a contribution to the earthquake locations contained in this website. This information is not exhaustive of all the seismic stations installed today in Italy or in the neighbour countries, nor of the many stations that have been operative in the past.
The instrumental parameters published are defined by the StationXML format .
