Abstract

The divergent cluster of faults – zone of large submeridional Pelusian arc, breaks Sinai microplate. Large sinistral displacement of this zone caused a set of geomorphic effects: formation of folded morphostructures of the Sinai microplate, development of morphostructures of the Red Sea rift, decay of the Thetis into two basins, northward movement of Africa, its Eastern drift from Mid-Atlantic ridge, and articulate latitudinal sheer of the latter. During Cenozoic and recent epochs arc-like fault morphostructures were formed. Being superimposed on Pelusian zone structures, they form complicated network of block morphostructures, which undergoes movements of different directions. A set of short low-amplitude seismic faults controls the southeast part of the Mediterranean seashore.
