Fig. 2From: Full, constrained and stochastic source inversions support evidence for volumetric changes during the Basel earthquake sequenceSeismograms of event 113 (ML 2.5) recorded at Stations OTTER (a) and SBIS (b). Top panels show unfiltered acceleration seismograms, bottom panels show bandpass filtered (0.5–3 Hz) displacement seismograms. ‘OT’ corresponds to origin time. Note the impulsive P-wave arrival visible in the unfiltered data. In the bandpass filtered data, the horizontally polarized S-wave dominates the seismogramsBack to article page
