Point Source
SISMOWINE WP2_LOH1
SISMOWINE is intended as a longterm interactive web interface for verifying numerical modeling methods in seismology. Numericalmethod developers and numerical modelers may compare their solutions with other solutions. SISMOWINE is a continuation of the original SPICE Code Validation interface established within the 6th Framework Programme project.
LOH1 is used as an example here to illustrate the implementation of source point for earthquake nucleation in SeisSol. The details of the LOH1 model can also be found at the point source example.
The model uses Righthanded Cartesian, x positive North, y positive East, z positive downward, all coordinates in meters. The source is buried at 2000 m in a halfspace Earth (Figure [fig:loh1]. The top layer is 1000 m thick and the bottom layer is 33000 m. The material parameters are listed in Table [table:loh1].
