Input requirements and assumptions for ITER consider that an infrequent, severe earthquake which, although unlikely to occur during the lifetime of the facility, is assessed to demonstrate adequate protection of the public. This earthquake is assumed to have a return period of 10.000 years. An investment protection level or inspection level with a peak ground acceleration at 0.5m/s{2} is also considered. As a basis, orders of magnitude of consequences, if no countermeasures were taken, are given.
The European site proposed for ITER is situated in the South of France, 40 km North-East of Aix-en-Provonce, in a low to moderate seismic area according to the Global Seismic Hazard Map. The Tokamak building would be implemented on good bedrock made of limestone with a shear wave velocity of over 1.300 m/s
