Abstract

In the last 10 years, the infrasonic monitoring has become one of the most effective tool to characterize the volcano activity. In 2006, the infrasonic permanent network, run by Istituto Nazionale di Geofisica e Vulcanologia, Osservatorio Etneo- Sezione di Catania (INGV-OE), was installed at Mt. Etna. Today, this network is made up of 10 stations. In order to process the data recorded by these stations, an automatic system, composed of 4 software, has been developed, allowing to detect, characterize in terms of amplitude and spectral content, and locate infrasonic events and tremor generated by the volcano. The processing results are stored in ASCII files, and successively the information written in them are imported in the INGV-OE database by software loader, specifically developed. The information provided by this automatic system are available in near real-time to the people on duty in the control room, where the data regarding infrasonic source locations and occurrence rate of infrasonic events are always visible. Moreover, such data are used to give further data on the volcano state of health for INGVOE internal monitoring purposes or to provide additional information to the Civil Protection.
