Seismo-Lineaments in Egypt: Analysis and Implications for Active Tectonic Structures and Earthquake Magnitudes

Quiescent faults may be capable of creating catastrophic earthquakes in locations with moderate and/or low seismic activity, such as Egypt. This study combines structural, remote sensing (RS), geophysical, and activity data to examine analyze the relationship between tectonic structures seismotectonic In a new seismo-lineaments map Egypt, lineaments Egyptian mainland were delineated classified. The database contains 8000 that divided into distinct geographical zones using statistical analysis general features. Delineated integrated digitized geological geophysical surface subsurface geographic information systems (GIS) processing techniques applied produce 4249 faults. spatial distribution was determined extract 1968 competent out (i.e., greater than 10 km suitably orientated concerning existing stress field). Maximum expected magnitudes (Mmax) calculated for seismogenic taking account nature regional rupture. At national scale, empirical scaling relations fault lengths earthquake magnitude employed all mapped findings highly consistent traditional information. results suggest our technique estimating highest predicted produces similar values might used evaluate Egypt’s possible future hazard. compared databases. similarity those reported catalogs lends confidence proposed scheme.
