Lithosphere deformation

Web23 jul. 2024 · In the upper lithosphere, deformation is characterized by frictional sliding on preexisting planes, where strength (i.e., a scalar value equal to the greatest differential stress at failure) typically is calculated using the linear, pressure-dependent Byerlee's law [ Byerlee, 1978 ]. Web[1] We measure ground motion around the Lake Mead, Nevada, using synthetic aperture radar interferometry. The lake water level has fluctuated through time since impoundment in 1935. To quantify the deformation due to water level variations over the past decade, and to constrain the crust and mantle rheological parameters in the lake area, we analyze …
