The faults are normal faults which dip to the west.
In fact, the major normal faults tend to diverge around the center of the core and join at either end.
At the western end, the base has dropped down along normal faults, forming a graben structure.
Several other normal faults also developed on the plateau.
A normal fault occurs when the crust is extended.
The age relationship between the grabens and normal faults is complex.
The final type of fault is called a normal fault.
They bounded by normal faults to the north and west.
Earthquakes associated with normal faults are generally less than magnitude 7.
A horst is the raised fault block bound by normal faults.
