Ground acceleration (left panels, black seismograms) and velocity (right panels, red seismograms) as recorded at three selected strong-motion stations located within 25 km of the epicentre of the ML 4.6 Urnerboden earthquake of March 6, 2017. The data are restituted (corrected to account for the instrumental response) to ground motions and filtered with an acausal bandpass filter between 0.3 Hz and 80% of the Nyquist frequency (for details see Cauzzi et al. 2016). Site class (SIA), shallow shear-wave Vs velocity (VS,30) and epicentral distance (Re) are indicated for each station
