Lithosphere deformation
WebTearing of the lithosphere at the lateral end of a subduction zone is a consequence of ongoing subduction. The location of active lithospheric tearing is known as a Subduction … WebDepartment of Earth Sciences » Lithospheric flexure.

http://earthsci.org/education/teacher/basicgeol/deform/deform.html WebSatellite geodetic techniques that can measure displacements with millimeter-level accuracy reveal transient signals in the deformation fields produced by both moderate and large earthquakes. These post-seismic signals exhibit characteristic time scales ranging from weeks to decades and distance scales from hundreds of meters to hundreds of kilometers.
WebIn geodynamics, delamination refers to the loss and sinking (foundering) of the portion of the lowermost lithosphere from the tectonic plate to which it was attached. Mechanism [ edit] The outer portion of the Earth is divided into an upper, lithosphere layer and a lower, asthenosphere layer. WebTemperature - in particular for crystal plastic (dislocation creep etc.) deformation mechanisms. The geothermal gradient lies between 15-35 °C/km, with the lower values …
