From: Seismic signature of the deadly snow avalanche of January 18, 2017, at Rigopiano (Italy)

Seismic traces recorded at station GIGS: (a) 24 min zoom for the avalanche time window, (b) 20 s zoom, containing the displacement trace generated by the avalanche, (c) spectrogram of the E-component of station GIGS plotted for the 20 s-time window of (b), generated by the avalanche. [Panels a and b have been plotted by using Snuffler, https://pyrocko.org; Panel c was realized using SAC-software: https://ds.iris.edu/ds/nodes/dmc/forms/sac/].
