The Friuli Automatic Alert System (FAAS; Bragato and Govoni, 2000) is a rapid-location system developed in 1996 to satisfy the requirements of the Civil Protection of Friuli- Venezia Giulia. FAAS runs on the same computer running the MARS88/RC acquisition system. It is composed of three modules (Analyzer, Decision Maker, and Communicator) implemented as independent processes that communicate through standard files. The Analyzer draws data from the signal database and starts processing if a coincidence arises among at least four stations. It recognizes local earthquakes based on the frequency content of the seismograms, performs P and S picking, locates the earthquakes, and estimates their magnitudes. The results of the analysis are sent to the Decision Maker, which establishes the level of alert and the users to notify (in particular, authorities responsible for emergency management and seismological institutions). The Communicator produces the appropriate messages and sends them by fax, e-mail, or short messages on the cellular phone. Automatic locations are also reported on the CRS Web page (http://www.crs.inogs.it/) and on a monitor located in the emergency room of the Civil Protection of Friuli-Venezia Giulia. During the night and off-duty days, the system also alerts a seismologist by cellular phone. If necessary, the seismologist can reach CRS in about half an hour to verify the earthquake's location, follow any seismic sequence, and support decisions by Civil Protection authorities. For regional or teleseismic earthquakes, FAAS e-mails other seismological institutions with messages containing P arrival times. Due to the transmission modalities described before, FAAS has a response time (from the origin time of the earthquake to the production of the first location) of about 7 minutes.

Abstract

The Friuli Automatic Alert System (FAAS; Bragato and Govoni, 2000) is a rapid-location system developed in 1996 to satisfy the requirements of the Civil Protection of Friuli- Venezia Giulia. FAAS runs on the same computer running the MARS88/RC acquisition system. It is composed of three modules (Analyzer, Decision Maker, and Communicator) implemented as independent processes that communicate through standard files. The Analyzer draws data from the signal database and starts processing if a coincidence arises among at least four stations. It recognizes local earthquakes based on the frequency content of the seismograms, performs P and S picking, locates the earthquakes, and estimates their magnitudes. The results of the analysis are sent to the Decision Maker, which establishes the level of alert and the users to notify (in particular, authorities responsible for emergency management and seismological institutions). The Communicator produces the appropriate messages and sends them by fax, e-mail, or short messages on the cellular phone. Automatic locations are also reported on the CRS Web page (http://www.crs.inogs.it/) and on a monitor located in the emergency room of the Civil Protection of Friuli-Venezia Giulia. During the night and off-duty days, the system also alerts a seismologist by cellular phone. If necessary, the seismologist can reach CRS in about half an hour to verify the earthquake's location, follow any seismic sequence, and support decisions by Civil Protection authorities. For regional or teleseismic earthquakes, FAAS e-mails other seismological institutions with messages containing P arrival times. Due to the transmission modalities described before, FAAS has a response time (from the origin time of the earthquake to the production of the first location) of about 7 minutes.
