Post-seismic assignment for BERSSIN


The IRSN's Seismic Hazard Assessment Bureau for Nuclear Facility Safety (BERSSIN) has taken part in a six-day post-seismic survey in the Abruzzo region of Italy, at the request of the French Earthquake Engineering Association (AFPS).
A BERSSIN geologist, Hervé Jomard, has joined the 12 specialists of the multidisciplinary team and the three Ministry representatives (1) on their assignment in this region in central Italy, which was severely hit by an earthquake of magnitude 6.3 during the night on 5-6 April 2009. The quake claimed many lives and destroyed numerous buildings in the city of L'Aquila, which is located almost directly above the epicentre. The assignment report will present a full inventory of the situation based on all the data relating to the event, including recordings, structural behaviour of buildings and crisis management. The report will teach us more about what happened, particularly the geological aspects involved, which are the focus of our expert's task.

BERSSIN carries out assessments of the seismic hazard as part of the examination of nuclear facility safety analysis reports and related documentation, thus helping to ensure that regulations are updated as necessary. It is therefore ideally qualified for studying this type of event. Hervé Jomard left on Saturday 18 April, arriving the next day, just as another after-shock occurred!
