MOBILE SEISMIC NETWORK

Temporary seismic station installed in Sillano, in the province of Lucca, following the seismic sequence that occurred in Lunigiana in 2013.Temporary seismic station installed in Bolognola, in the province of Macerata, during the long seismic sequence that occurred in Central Italy after the Amatrice earthquake of 24 August 2016. Temporary seismic stations installed in Guglionesi, Lupara and San Martino in Pensilis, in the province of Campobasso, following the Mw 4.9 earthquake of August 16, 2018.

Seismic and volcanic monitoring of the national territory is one of the main institutional tasks of the National Institute of Geophysics and Volcanology (INGV).
INGV performs this important function through the management and maintenance of permanent networks of different types and at different scales. In some areas, the density of these networks, in addition to guaranteeing the monitoring of seismic and volcanic activity, also makes it possible to record and precisely locate low-magnitude events, allowing the seismic release of the area to be studied in detail.
To temporarily increase the density of the permanent networks by improving their quality and seismic detection capacity, INGV has a Mobile Seismic Network infrastructure made up of over 100 stations which can be equipped with velocimetric, accelerometric and infrasonic sensors with different technical characteristics which allow extensive control of the frequency spectrum emitted by the seismic source. The strong technological development of recent years has also allowed the implementation of temporary seismic monitoring systems in real time (ie in UMTS or satellite telemetry) of particular importance for the analysis of a seismic sequence following a strong earthquake or during a persistent earthquake swarm.
The instrumental park of the INGV Mobile Seismic Network is used by INGV researchers, technologists and technicians in the context of targeted scientific projects and during seismic emergencies, within the activities envisaged by the operational group EARTHQUAKE. In volcanic areas, the Mobile Seismic Network can contribute to a more detailed observation of the phenomena in progress, in particular by improving where necessary the recording of the continuous signal and of the transients linked to volcanic degassing.
Mobile Seismic Network Units are present at the National Earthquake Observatory in the various offices in Ancona, Grottaminarda, Palermo, Rende and Rome, the Etna Observatory in Catania, the Vesuvius Observatory in Naples, the Section of Pisa and the Milan Section.
