SPECFEM3D Cartesian on the Moon - on April 19, 1972, the Apollo 16 S-IVB rocket booster was sent on collision with the Moon for a seismic experiment to study Moon's interior. Simulation includes subsurface scatterers and Apollo 12 seismic station #specfem3d

#specfem3d peak-ground motion (PGV) shakemap of the time-reversal simulation of the Birch glacier collapse. it should highlight the event site - but sometimes things are not so simple.

#specfem3d time-reversal simulation of the Birch glacier collapse. Reinjecting seismic data from all available Swiss broadband stations together with the velocity model from Diehl et al. (2021) pinpoints the source of all that seismic energy...
