Why is your contribution important?

Your observations can help improve earthquake response and also contribute to scientific knowledge. Observations (including questionnaires, pictures, etc.) can provide valuable in-situ constraints on earthquake effects and, in the long term, improve the performance of our models of earthquake impact.

 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.

Intensity map created with the results of the macroseismic questionnaires (click the map to enlarge).If you have experienced this event, please report it by filling our online questionnaire.
