Parameter determination for flank collapse event detection. a Seismogram cross-correlations at four frequency bands. Red lines denote the fitted phase velocity to explain the peak delay times. Red circles highlight the peak delay times at higher frequencies. b Measured and fitted seismic quality factors. c Frequency-dependent local amplitude corrections for each station
