During the last decades, and especially in the last few years, seismological monitoring has undergone great improvements thanks to the introduction of seismic arrays with small radii and very dense seismological networks, equipped with high dynamics systems.
This has made it possible to significantly improve the minimum level of recognition of an event, especially in the near "real-time" environment, making it possible to identify active structures.
The use of advanced data processing techniques, such as "beam forming", the F-K analysis of the signal, makes it possible to analyze the apparent speed and the back-azimuth angle of the wavefront, allowing the localization of events of very low magnitude, even less than 0.
In collaboration with INGV, we have created an array (Central Italian Seismic Array) with a maximum radius of 1000m, made up of 9 triaxial velocimetric stations of 5s.
The red star represents the placement of the C.I.S.AR Array.
Localization of all events occurred from 01/01/2019 to 07/22/2019.
The array made it possible to locate various events in the Monti Martani, near Perugia and the clusters that were activated in Giano dell'Umbria and Spoleto.
