The propagation of nonlinear Love waves in an elastic, vertically heterogeneous crust laid upon semi-space is considered. By employing the multiple scales method, amplitude function represented by a Schrödinger equation which includes material and heterogeneity parameters layered its coefficients. This study numerically investigates influence as well properties media on presence bright dark sol...

Earthquakes can be triggered by local changes in the stress field (static triggering) due to nearby earthquakes or by stresses caused by the passage of surface (Rayleigh and Love) waves from a remote, large earthquake (dynamic triggering). However, the mechanism, frequency, controlling factors and the global extent of dynamic triggering are yet to be fully understood. Because Rayleigh waves inv...

the mixture of natural and artificial seismic sources with random distributions cause diffuse wave field with random amplitudes and phases called noise. when noise is analyzed in a long-term process, it contains surface waves which are spread in all directions. thus, ambient noise contains data relevant to the surface waves. in recent years, as broadband seismic networks have been distributed v...

Propagation of Love-type waves is investigated in a model multilayered elastic solid half-space containing voids. Using Haskell matrix method, the dispersion relations are derived for two situations topmost boundary surface model: (a) when it stress-free and (b) rigid. For both situations, there exist fronts that dispersive nature propagating with distinct speeds. One these wave analogous to ob...
