As part of the Cascadia CoPes Hub project, a new set of 36 ground motions have been computed using 3D simulations, archived at Dunham et al. (2025).
The surface deformation from these ground motions can be used as sources for tsunami simulations. Several different versions of these have been computing, including for the full time-dependent kinematic rupture, but also static displacements for “instantaneous” tsunami generation, as described elsewhere. To use these ground motions in simulations on TACC, see Shared data files on TACC.
Summary of sources¶
As shorthand in the tsunami simulations, we use the following set of short names (and also the event number when setting up job runs for subsets of these events, as described in Running the same GeoClaw setup with many dtopo files.
See the dtopo/GroundMotions.ipynb notebook for some additional information and tools for working with these.
