Structural analysis of recent seismic fissures and neotectonics in Yemen

الملخص EN

Recent seismic fissures in various trends are distinguished in the alluvium covering and the bedrocks of many basins in Yemen such as Amran Basin.

Obviously, these fissures are systematic and signal continuous propagation in the area.

These fissures in the Jahran basin as an example, have been analyzed to know the new mechanism style and paleostress systems that have prevalent in the Yemen area.

These fractures have be caused by shear and extensional stresses with faults propagated in this basin.

These groups of fissures serve as the geometrical classification applied with the ancient groups that are spread in the Tertiary and Quaternary Volcanic Zone, indicating that the fault activities are being reactivated, and this activity is the result of the recent tectonic and volcanic processes in the southern parts of the Red Sea.
