How has the National Seismic Network (RSN) evolved and developed from the few observation points scattered throughout Italy to the hundreds of multi-parameter stations of our days?
On the occasion of the XNUMXth anniversary of the National Institute of Geophysics and Volcanology (INGV), INGVterremoti has created a new story map that recounts the development over the years of the RSN, one of the Institute's most important infrastructures which allows seismicity to be monitored in Italy and in the world and to ensure the seismic surveillance service of our territory for the Civil Protection Department (DPC).
The story map offers a historical reconstruction of the development of the INGV (formerly ING) monitoring network which, following the earthquake in Irpinia on November 23, 1980, was centralized to provide a national monitoring and surveillance service in real time or almost.
Through the aid of interactive maps, texts, photos and historical and recent images, the main aspects relating to the technological and instrumental development of monitoring stations (sensors, receivers, data transmission, power supply), the increase in the number of stations and finally to the consequent evolution of the surveillance service (location of events, 24-hour shifts, communication to the DPC and the public).
Today the Integrated National Seismic Network, thanks also to the contribution of data from foreign stations installed in neighboring regions, has almost 500 stations.
