Method
The key features that allow recognition of active scarps are (1) detailed fieldwork where faults shown on existing geological maps are visited and assessed for fault activity (see Roberts and Michetti 2004, Papanikoloau and Roberts 2007 for details), (2) remotely-sensed (e.g. SPOT) images of the scarps themselves, (3) incised drainage in the uplifted footwalls of the scarps that are best-visualised in digital elevation models (DEMs), (4) escarpments in the footwall of the scarps, that show a variety of topographic features characteristic of active normal faulting such as triangular facets and oversteepened basal profiles (again, best-visualised in DEMs). This study details the results of fieldwork presented in Roberts and Michetti (2004) and Papanikoloau and Roberts (2007), that have now been correlated with observations from SPOT images and the DEM in Google Earth. This allows documentation of the precise latitudes and longitudes of paths that define the active fault scarps. First, images of typical landforms associated with scarps are presented, followed by a regional analysis of the fault scarps.
