Description:
Seismic networks are powerful tools for understanding active tectonic
processes in a monitored region. Their numerous applications, from monitoring
seismicity to characterizing seismogenic volumes and generated seismicity, make
seismic networks essential tools for assessing seismic hazard in active regions. The
ability to locate earthquakes hypocenters requires a seismic network with a sufficient
number of optimally distributed, stations. It is important to assess existing network
geometry, to identify seismogenic volumes that are not adequately monitored, and
to quantify measures that will allow network improvement. In this work we have
studied the spatial arrangement of the stations of the Italian National Seismic Network
by means of several Point Pattern techniques The results of the point patter
analysis were compare with the spatial distribution of the historical and instrument
seismicity and with the distribution of the well know seismogenetic sources of the
Italian peninsula. Some considerations have also been made on some models of seismic
hazard of the Italian territory. Our analysis allowed us to identify some critical
areas that could require an optimization of the monitoring network.
