Seismic potency
WebEach group of seismic events can be scrutinised using various plotting tools: event size distributions (where the size is expressed in terms of seismic potency, seismic energy or magnitude) time histories of parameters of seismicity time-of-day and day-of-week distributions of number of events WebNov 1, 2016 · We develop a simple methodology for reliable automated estimation of the low-frequency asymptote in seismic body wave spectra of small to moderate local earthquakes. The procedure corrects individual P- and S-wave spectra for propagation and site effects and estimates the seismic potency from a stacked spectrum. The method is …
