SeIsmic Ground Motion Assessment project, v.2


This website will be under construction for some weeks. It will still be accessible most of the time as we will update the content and design progressively.

We apologize in advance for any inconvenience the update might cause.


SIGMA-2 is a Research and Developpement project about seismic hazard and ground motion.

It is funded by a consortium of industrial companies:

  • EDF (France)
  • Pacific Gas & Electricity (USA)
  • swissnuclear (Switzerland)
  • CEA (France)
  • CEZ (Cech Republic)
  • Orano (France)
  • CRIEPI (Japan)

It has the objective to improve data and develop methods necessary to best estimate SHA by producing Hazard levels more adapted to the site.

The main topics are :
