  1. “Cutoff” indicates the cutoff period of the low-pass filter applied to the waveform. σ represents the standard deviation in runup heights over the entire time series of manually extracted waveforms, “RMSE” indicates the root mean squared error of runup height of the CCTV-extracted waveforms relative to the manually extracted ones, and “Correlation” denotes the correlation between the two sets
