A simple model to analytically assess the SH seismoelectric response of the vadose zone

Mostrar todas las versiones(2)

In this work an analytical solution of the seismoelectric conversions generated in the vadose zone, when this region is traversed by a pure SH wave, is derived. The considered model assumes a one-dimensional soil constituted by two homogeneous media in contact at the water table, and a shearing forc...
