Rete Sismica Nazionale (RSN)

The Italian National Seismic Network (Italian: Rete Sismica Nazionale, RSN) is the nationwide permanent seismological network operated by the National Institute for Geophysics and Volcanology (Italian: Istituto Nazionale di Geofisica e Vulcanologia, INGV) with contributions from collaborating institutions and observatories. Initially, it was deployed mainly as a seismic monitoring facility and over the years has grown both in quantity and in quality of the installed instruments. Thereby it also gained importance as a valuable research infrastructure. It now consists of various types of seismic sensors, i.e. short period, broadband and accelorometric instruments, which are collocated at many sites, and it is the largest Italian seismological network by number of sensors and by geographical extent. All stations are connected to the datacentre through a variety of technologies and are transmitting sensor data in real time. Data is distributed through the Orfeus European Integrated Data Archive (EIDA) federation and International Federation of Digital Seismograph Networks (FDSN) standard protocols under an open definition compliant license.
