Shiraz is situated in south of Iran and within the Zagros mountain ridge.
Seismological and geological studies reveal the fact that, from 840 B.C until the present day, many earthquakes have devastated this historical city.
Studies indicate that the epicenters of the majority of the recorded earthquakes are within 30 kilometers of the city and over the Mok-Sabzpooshan fault zone and its associated branches. This fault zone, which has more than 87 kilometers of length, starts from the north of Firoozabad and continues up to north west of Shiraz and is constituted from three aligned sections of southern, middle and northern orientation.
Fractal dimensions of different segments and the entire aforementioned fault zone indicated its recent creation and that of all of its three sections. The predominant mechanism of this fault is dextral strike slip and the northern section which is situated in the west of Shiraz develops compressive elements.
Considering the latest empirical and mathematical models, the highest perceivable capacity of this fault in producing an earthquake magnitude is Ms 6.9 which can deliver accelerations of up to a=0.45g in several areas of Shiraz.
