Geologic process identification through landform analysis

Sun, 08/24/2014 - 2:53pm -- Anonymous (not verified)

Surface topography is generated by geologic activity, typically by tectonic forces, and in return tectonically driven landforms are indicative of seismic hazards. Using Raster Calculator, Focal Statistics and other Spatial Analyst tools to quickly identify tectonically generated topographic features can be used to (1) highlight areas of high seismic hazard, (2) locate previously unidentified fault structures, and (3) to check the accuracy previously published data. These techniques are useful for both hazard analysis and geologic mapping applications.
