Earthquake in Central Italy

Document Actions

It is a year since the first shock of the long seismic sequence that hit central Italy from august 24. During this period, ISPRA in the whole of SNPA system has participated in all the emergent phases, giving its technical, scientific and professional contribution to support first  all the safety with over 400 inspections carried out over the first 6 months, for the geoidrological compatibility of sites with the different purposes in emergency and then programming the reconstruction. Besides, the technical scientific activities are still working to support to seismic microzonation in the 140 municipalities affected by earthquake, in the framework of a large cooperation with many other Institutes and Body research, in order to contribute to  a sensitive reconstruction, taking into account the local geological reality, promoting the correct application of the current anti-seismic regulations.

    The data collected from the continuous GPS stations managed by the ISPRA Geophysical Service (named CATO, LEOF and TERM) have contributed together with the data acquired from the stations of other Institutes (INGV-RING, DPC, ItalPos, NetGeo, ASI ...) , to the definition of cosismic deformations associated with the event of August 24, 2016.

    These data have allowed to define the fault geometry and the slip associated with the event as well as the dynamic motion of the soil through the analysis of High-Rate data such as described in the following publications:
