Seismic potency
WebSeismograms can be displayed as acceleration, velocity or displacement traces, in standard mode, unrotated modes or polarised modes. Spectra of seismic waves can be analysed to detect noise and adaptively remove it. WebJun 11, 2024 · The simulation was repeated several times to optimise the residual values of friction angle, dilation angle and cohesion. This was done such that the total modelled seismic potency defined by Eq. best matches the total observed seismic potency in the area over the same period and these optimised values are those given in Table 2. Once these ...
