Abstract

Nubian Desert is a natural laboratory for studying process of active intraplate strike-slip. The area is dominated by E-W and N-S oriented faults that can be traced for hundred kms. Both trends are tectonically active and witness several seismic events during Late Quaternary. Focal mechanisms and geomorphologic evidences indicate left-lateral strike-slip movement along the N-S and right-lateral strike-slip movement along the E-W faults. The field investigation and analysis of the high resolution satellite images reveals that recent seismicity produced several surface rupture zones along the pre-existing N-S left-lateral and E-W right-lateral strike-slip fault zones. The mapped co-seismic cracks have ENE, WNW, NNE and E-W orientations. The Four trends are genetically related and could attribute to simple shearing along N-S or E-W shear zone.
