Abstract
The propagation of Love waves in models with local inhomogeneities (a canyon or an alluvial valley), which are related to general waste deposit problems in environmental geophysics, is investigated. The numerical study is based on a direct boundary element method for calculating wave fields and on a Green’s function technique for evaluating transmission, reflection and “diffraction” coefficients for Love waves, incident on a local surface or subsurface irregularity in layered media. The object of this study is to show the sensitive characteristics of Love waves to local inhomogeneities which can be very useful in environmental and engineering geophysics for the detection and identification of underground anomalies.
