Tectonic Summary

This earthquake occurred as the result of stresses generated by the motion of the Arabian plate northward against the Eurasian plate at a rate of 2 to 3 cm/year (about one inch per year). Deformation of the Earth's crust in response to the plate motion takes place in a broad zone that spans the entire width of Iran and extends into Turkmenistan. Earthquakes occur primarily as the result of reverse faulting and strike-slip faulting within the zone of deformation. The March 31 earthquake occurred close to the Main Recent Fault, a major strike-slip fault, but we do not know at present if the earthquake occurred on that fault or on a related smaller fault.

The section of the Main Recent Fault near the epicenter of the March 31 earthquake produced a magnitude 7.4 earthquake in 1909.
