Webb7 jan. 2024 · Long-period seismic waves. Large and rapid landslides often generate strong long-period seismic waves due to the interaction between the flow and the Earth. According to the theory of a single-force mechanism, the seismogram at a given station is the result of the convolution of the force-time function and the Green’s function (Eq. 9). Webb1 apr. 2024 · Among them, 18 landslides were detected and located by using short-period (0.25–1 s) seismic records near the landslide sources (Yamada et al. 2012).
