LA RETE SISMICA DELLA PIANA DI GUIDONIA (LAZIO): DATI PRELIMINARI

After the seismic period during 2001-2002 that has interested the Plain of Guidonia, situated
about fifteen kilometres NE of Rome, which events greatest resentment reached the V-VI MCS, have
been installed a local seismic purchased by Comune of Guidonia-Montecelio (Rm). The seismic
network (RLG) consists of three digital seismic stations with distances of each other about 2
kilometers, activated to leave from the June 2004 and equipped with three components 1 Hz
sismometer. Subsequently, the RLG has enriched of other four digital stations equipped with three
components 5 Hz sismometer This network has like main objective the high quality data that agree a
better definition of the seismic local activity. These data, that integrate those of the Seismographic
Centralized National Network (SCNN), agreed a better ipocentre location. Network geometriy was
chosen so as to give back the RLG an independent structure to carry out reliable seismicity locations
that characterizes the plain of Guidonia. Unfortunately, industrial and human activity, increases in
considerable manner the seismic noise, giving back difficult the record of small events. For this motive
the location of the sites was more times changed, and lately, after a seismic crisis in the northern side
of the Mountains Cornicolani, that has presented with the same features of that of 2001 of Guidonia,
some stations were moved in the neighboring village of Palombara Sabina (Rm).
