DBMI04: The database of macroseismic observations of Italian earthquakes used for compiling the parametric catalogue CPTI04,DBMI04 il database delle osservazioni macrosismiche dei terremoti italiani utilizzate per la compilazione del catalogo parametrico CPTI04

This paper describes the main features of the Macroseismic Database of Italy 2004, which for the first time put together in a critical way the macroseismic data used for the compilation of the CPTI04 (2004) parametric earthquake catalogue. Data come from varied main datasets: i) DOM4.1 (Monachesi e Stucchi, 1997); ii) CFTI version 2 (Boschi et al., 1997) and, for the time-window 1980-2002, CFTI ver- sion 3 (Boschi et al., 2000); iii) Bollettino Macrosismico ING (BMING); iv) Catalogo Macrosismico dei Terremoti Etnei, Azzaro et al. (2000; 2002). In addition, data from recent his- torical and field investigation were also used. DBMI04 contains 58146 macroseismic observa- tions related to 1041 earthquakes and 14161 localities, 12943 of which in Italy. The input data used for the compilation of DBMI04 were not homogeneous with respect to the use of the intensity scale and, mainly, to geo- graphical reference. One of the main task was the organisation of a reliable geographical refer- ence, based on the previous ENEL-ISTAT cata- logue of the Italian localities (ENEL, 1978), which was updated by means of new data. Another task consisted in correcting some mis- takes performed when associating the place- names quoted by the historical sources and the geographical reference. Some problems were solved using ad hoc conventions for dealing with observations not expressed in terms of macroseismic intensity. Il lavoro presenta le soluzioni adottate e la descrizione dell’interfaccia web attraverso la quale il database viene reso disponibile al pub- blico (http://emidius.mi.ingv.it/DBMI04/). This paper presents the adopted solutions and the results, together with the web-interface through which the database is made available to the public (http://emidius.mi.ingv.it/DBMI04/)
