Furthermore, to avoid the association with wrong events, we filter testimonies in distance and in intensity depending on the magnitude of the seismic event.

Regional instrumental seismicity
This seismicity maps have been generated by concatenating the ISC catalogue (since 1964), the EMSC Euro-Med Bulletin catalogue and the EMSC Real Time catalogue. Therefore, they show the seismicity from 1964 until the earthquake occurrence.
