Abstract
Abstract. The Istituto Nazionale di Geofisica e Vulcanologia (INGV) is an Italian research institution, with focus on Earth Sciences. INGV runs the Italian National Seismic Network (Rete Sismica Nazionale, RSN) and other networks at national scale for monitoring earthquakes and tsunami as a part of the National Civil Protection System coordinated by the Italian Department of Civil Protection (Dipartimento di Protezione Civile, DPC). RSN is composed of about 400 stations, mainly broadband, installed in the Country and in the surrounding regions; about 110 stations feature also co-located strong motion instruments, and about 180 have GPS receivers and belong to the National GPS network (Rete Integrata Nazionale GPS, RING). The data acquisition system was designed to accomplish, in near-real-time, automatic earthquake detection, hypocenter and magnitude determination, moment tensors, shake maps and other products of interest for DPC. Database archiving of all parametric results are closely linked to the existing procedures of the INGV seismic monitoring environment and surveillance procedures. INGV is one of the primary nodes of ORFEUS (Observatories & Research Facilities for European Seismology) EIDA (European Integrated Data Archive) for the archiving and distribution of continuous, quality checked seismic data. The strong motion network data are archived and distributed both in EIDA and in event based archives; GPS data, from the RING network are also archived, analyzed and distributed at INGV. Overall, the Italian earthquake surveillance service provides, in quasi real-time, hypocenter parameters to the DPC. These are then revised routinely by the analysts of the Italian Seismic Bulletin (Bollettino Sismico Italiano, BSI). The results are published on the web, these are available to both the scientific community and the general public. The INGV surveillance includes a pre-operational tsunami alert service since INGV is one of the Tsunami Service providers of the North-eastern Atlantic and Mediterranean Tsunami warning System (NEAMTWS).
Highlights
The Istituto Nazionale di Geofisica e Vulcanologia (INGV) is an important Italian public research institution; INGV carries on research in the Earth Sciences combining data from geophysical networks and results from fundamental research into the assessment of geo-hazards
The data are archived and distributed through web portal developed by INGV and integrated at European and global scales
The data recorded by the monitoring networks are transmitted in real-time to the operational rooms in Rome, Naples and Catania, where highly trained 24/7 staff analyze them to obtain the main parameters of the ongoing events and processes
Summary
The Istituto Nazionale di Geofisica e Vulcanologia (INGV) is an important Italian public research institution (http://www. ingv.it/en/); INGV carries on research in the Earth Sciences combining data from geophysical networks and results from fundamental research into the assessment of geo-hazards. INGV is the reference institution of the Italian Department of Civil Protection (Dipartimento di Protezione Civile, DPC), and is part of the National Civil Protection System. It is in charge of the surveillance of the seismicity and volcanic activity of the entire national territory through stateof-the-art instrumental networks covering Italy and concentrated around the main active volcanoes. We describe the various networks, databases and monitoring products of the National Earthquake Center (Centro Nazionale Terremoti, CNT, one of the organizational units of INGV) and, concisely, the earthquake and tsunami surveillance systems at INGV Rome
