The present problem deals with the propagation of Love-type surface waves in a bedded structure comprises of an inhomogeneous orthotropic layer and an elastic half-space. The upper boundary and the interface between two media are considered to be corrugated. An analytical method (separation of variables) is adapted to solve the second order PDEs, which governs the equations of motion. Equations...

temper of learning when men study words not matter; for words are but the images of matter, and, except they have life of reason and invention to fall in love with them, is all one as to fall in love with a picture." The great prophet of inductive philosophy has here touched the very core of the errors and vanities which gather round epidemiological research, and impede progress in the acquisit...

[1] In several instances, the passing surface waves from large earthquakes have ignited nonvolcanic tremor (NVT) on major faults. Still, the mechanism of tremor and its reaction to the dynamic stressing from various body and surface waves is poorly understood. We examine tremor near Parkfield, California, beneath the San Andreas fault triggered by the Mw 9.2, 2004 Sumatra earthquake. The prolon...
