Geodatabase e report di sismicità

Abstract

The laboratory of digital cartography and geographical information systems (LABGIS) of the ISTITUTO NAZIONALE di GEOFISICA e VULCANOLOGIA (INGV) in Grottaminarda (AV) has focused its activity on the organization and processing of a high number of cartographic, territorial, geological and geophysical data regarding Central and Southern Italy. This activity represents one of the purposes of CESIS Project whose aims are to realize a monitoring network of permanent stations with seismic, accelerometric and geodetic instruments and to create a Centre for Seismology and Seismic Engineering. The realization of a series of geographical database in ESRI Geodatabase data model with the software ArcGIS 9 has offered the possibility of trying out the opportunities of this technology as, for example, the organization of different types of geographical data and proceedings inside the same environment. The following step was to develop a series of applications as the SIT CESIS EARTHQUAKE REPORT. This application produces a cartographic report, which is able to give a territorial and seismological view for each earthquake of magnitude greater than 3.0 recorded in Southern Italy. The report contains information deriving from the historical and instrumental seismicity catalogues and information about the location of monitoring network stations, the seismic hazard and classification. All these data are produced by the INGV. This instrument is very important for the activity of seismic monitoring because it is able to give an immediate and complete answer, regarding to an occurred earthquake to the National Department of Civil Protection. That’s why it has been thought to extent the creation of a report to all the national territory, by increasing the database and developing a specific GIS application that can be used, in real time, in the seismic monitoring hall of the Centro Nazionale Terremoti in Rome.
