Effects of topography on surface fault geometry and kinematics : examples from the Alps, Italy and Tien Shan, Kazakstan

Auteur :

Description :
The kinematics and extent of surface faulting are usually determined using observations on morphostructures, such as escarpments, and measurements of the net displacement of geologic deposits and topographic features, such as gullies and ridges. This paper shows that these measurements can be misleading in rugged terrains if one does not take into account the effect of topography. To illustrate this effect, field data on surface deformations collected along Holocene faults of the Italian Alps and Kazakstan Tien Shan are compared with fault plane geometry and local topography.
