DEM-based morphometry of range-front escarpments in Attica, central Greece, and its relation to fault slip rates

Study of Beachrocks in East Attica

“…The wider area shows no indications of major earthquakes during the last 2500 years (Ambraseys and Jackson, 1998). Both historical and instrumental data provide no evidence for large earthquakes for the period 1700-2000, with the exception of two events, in 1705 and 1938 (Ganas et al, 2005;Papanikolaou and Papanikolaou, 2007).…”

Geological, Geomorphological and Tectonic Structure of Ne Attica and Seismic Hazard Implications for the Northern Edge of the Athens Plain

“…6). Considering that the finite throw towards the center of the fault is about 3 times higher (-360 m, see also Ganas et al 2005 who calculate a 350 m relief based on DEM analysis), the maximum rate is about 0.30 mm/yr. Following the above discussion, we estimate a mean rate of 0.15-0.20 mm/yr for this fault.…”

“…The southern Evoikos gulf is a shallow basin less than 250 m deep and the main fault of the Gulf has a throw of 250 m (Papanikolaou et al 1988a), implying that the Oropos-Kalamos zone as a whole is a relatively small structure and of similar importance as the other across strike faults; 2) the ~10 km long Milesi fault, which produces a characteristic bedrock scarp on the Mesozoic limestones that form the footwall and the continental Neogene sediments resting on the hangingwall; 3) the ~ 18 km long Avlona-Malakasa fault that borders the northern slopes of Parnitha Mt. (Papanikolaou et al 1988b, Ganas et al 2004); 4) the 14 km long Afidnai fault, which bounds the Afidnai plain to the south and the Athens Plain to the north (see also Ganas et al 2005).…”

Remote Sensing and Geographic Information System for Fault Segments Mapping a Study from Taiz Area, Yemen

“…Digital elevation models (DEMs) are very useful in aiding the classification of landforms for many purposes such as recognition of drainage patterns. Extraction of topographic feature information from DEMs has become increasingly popular in structural analysis [40]. Digital elevation models (DEMs) data were used to trace tectonic features and mapping geologically and topographically defined structures in many areas [41].…”
