Zusammenfassung:• Rockfalls are located using generated seismic signals at high frequencies for highly resolved spatial and temporal tracking • Rockfall location is improved using the signature of surface topography on seismic signals simulated with the 3D Spectral Element Method • By accounting for topography, all signal components can be used, critical in the case of sparse station networks or noise
