URI: https://registry.epos-eu.org/ncl/FAIR-Incubator/tcs-SEISMO/85
The frequency at which the curve representing the Fourier amplitude spectrum of a recorded seismic signal abruptly changes its slope and drops by -3 db from the spectral plateau. In earthquake source studies, a parameter characterizing the farfield body-wave displacement �source spectrum�, being related to fault size, rupture velocity, source duration and stress drop in the source
