Consistency between observed PEGS amplitudes and V17 modeling. Stacked trace (station-averaged vertical acceleration) of the same 27 sensors considered in Fig. 7a of K19, but deconvolving the data by the instrument response (as done in V17) before stacking. Note that the stacked trace Ss is shown with an opposite sign (scale to the right). The stack SNR (scale to the left) is defined as the ratio between |Ss| and the standard deviation of noise calculated in the 10 min preceding earthquake origin time. At the P wave arrival, Ss ~ − 1 nm/s2 and SNR ~ 14
