This features refer to abundance of surface morphological 
features indicate to Fresh Faults. Recent faulting is expressed as 
freshly exposed soil within the colluvial apron visible by its 
light tone color. These indicators had been proved by field 
checks. Furthermore, the statistic digital analysis of the spectral 
data show that there are distribution of spectral plumes. 
These plumes are decreasing in intensity and color contrast 
from the center of the site to the direction of its edges.

This proves that there are an active tectonic reflecting the 
behavior of the movement and earth stresses at these fracturing 
zones. Results from statistic analysis of DTM image( fig.8 ), 
demonstrate that the restraining bend of AL-Ghab graben 
involves active strike slip faulting. The AL-Ghab graben 
appears capable of generating large earthquakes and it should 
be an essential element in any regional earthquake hazards 
Assessment ( fig. 9).

AL- Ghab Basin is not a textbook example of a step-over 
basin. 
However, through comparison with other basin studies and 
models it was found that many of the second-order structures 
within AL-Ghab Basin are common to other strike-slip basins. 
The basin asymmetry seen in AL-Ghab is probably related to 
the amount, and sense, of relative movement across the 
bounding lateral faults.
