Regional Earth model and seismogram comparison. (a) Regional 1-D model of P-wave and S-wave speed, slightly modified from a seismic model of the wider Alpine region33 to better match observed waveforms from the Mulhouse event. (b) Comparison of observed (black) and computed (red) displacement waveforms for a selection of components and stations in the Basel-Bern region.
