Seven deaths were reported as a result of the 2008 earthquake.

One major hospital damaged by the earthquake was inundated with the injured and lacked medical supplies for treatment.

The sediments are affected by a series of large, mainly anticlinal folds that show a variety of trends in the central part of the island.

The axis of the Laft anticline runs mainly NW–SE, while the Salakh anticline trends roughly W–E and the Suza anticline and Ramkan syncline trend SW–NE.

The epicenter was about 1,500 kilometers (930 mi) south of Tehran, close to Iran's southern borders.

Initial measurements showed that the earthquake registered about 6.0 on the moment magnitude scale, although that was reduced to 5.8 after further analysis.

The pattern of uplift observed for this earthquake is also consistent with rupturing within the lower sedimentary sequence, but on a fault with two segments, dipping overall to the southeast.

Since it lies in such a seismically active area, there is a high risk of destructive earthquakes in Iran; 1 in 3,000 deaths are attributable to earthquakes.There is evidence of intermediate level detachment at some of the weaker layers, which means that folds at different stratigraphic levels may have different locations, orientations, or wavelengths.Measurements of earthquake focal mechanisms and hypocentral depths show that shortening is accommodated by a mixture of high-angle and low-angle reverse faulting, within either the lowest part of the sedimentary cover or in the basement beneath the Hormuz salt.The pattern of displacement is consistent with a north-dipping fault rupturing between about 8 kilometers (5 mi) and 4 kilometers (2 mi) in depth, which also provides a good match to the results of seismic modeling using body waves, The mismatch between the orientation of the fault planes that caused the earthquake and the observed surface folds suggests that deformation at these two levels is decoupled by the presence of a detachment, possibly within marl layers.Most aftershocks occurred at significantly greater depths than the mainshock and are dominated by strike-slip focal mechanisms.
