WP4: Strong ground motion modeling

Workpackage 4 is coordinated by F. Cotton (LGIT). WP 4 has the following objectives:

  1. Derive and characterize ground shaking in Europe for specified rock-conditions, with the corresponding calibrations for application to different soil classes in Europe.
  2. Coordinate the ground-motion specifications with the EC8 requirements.
  3. Build a European-wide consensus on the understanding of expected strong ground motions.

Workpackage 4 is structured in seven tasks:


The selection procedure of GMPE's can be depicted as follows:
