General Information
Databases

This catalog contains Etna's earthquakes localized by the seismic network of the Istituto Nazionale di Geofisica e Vulcanologia - Osservatorio Etneo, from 1999. Data are updated with a delay of seven days from the seismic event occurrence; they represent the best estimation of the hypocentral parameters. Any changes can be made later if necessary, without any notification.

Localizations are obtained through the software Hypoellipse 2.0 (Lahr, 1989) using several models of crustal velocity depending on the source area: Hirn et al., (1991) for the Etna and the north-eastern Sicily - southern Calabria, Jeffreys and Bullen (1967) for the Aeolian archipelago, Musumeci et al., (2003) for the south-eastern Sicily.
