With inv2 benchmarks, we updated the file formats used in the SIV benchmarks. While we continue the support for the legacy format. the updated formats are preferred especially for the recent benchmarks. The ground-motion data can be now uploaded in a .zip file containing the individual syn files. Another new feature is "ground displacement data". For details on the benchmark exercises, refer to problem description provided in the documents associated with each benchmark. Please do not hesitate to contact us if you would like to give a feedback.

Coordinate system

We use right-handed Cartesian coordinate system, with positive X pointing East, positive Y pointing North, and positive Z upward. All coordinates are defined in km.

Note: this corrected RHS-definition deviates from the one used in inv1 benchmark where Z was given as positive downward.
