Earthquakes in Iran from 1990 to 2006, by United States Geological Survey Iran Faults. Iran is one of the most seismically active countries in the world, being crossed by several major faults that cover at least 90% of the country. [1] As a result, earthquakes in Iran occur often and are destructive.
Iran lies on the fault line between the Arabian plate and the Eurasian plate. The collision of these two plates cause most of the earthquakes that strike Iran. The specific area of the fault that lies below the Sistan and Baluchestan province is referred to as the Makran region.

The fault ruptured by the Bam earthquake is believed to stretch the along northwest branch of this fault system from Bam southward. Based on these results, scientists suggest that the Bam earthquake ruptured a hidden fault and that in this process an unusually strong asperity was involved, causing the widespread devastation of the tremor.

Central Iran in a broad sense, comprising the whole area between the North and South Iranian ranges. Within the Iranian plate the Central-East Iran microplate is bordered by the Great Kavir Fault in the north, by the Nain–Baft Fault in the west and southwest and by the Harirud Fault in the east. It is surrounded by the Upper Cretaceous to ...
Both the 1968 Dasht-e-Bayez earthquake (magnitude 7.3, resulting in 12,000–20,000 deaths) and the Qayen earthquake were the results of strike-slip faults, meaning that the crustal blocks on either side of the faults shifted against each other horizontally. [7] The Qayen earthquake was caused by right lateral movement along the Abiz Fault. [8]
On 12 November 2017 at 18:18 UTC (21:48 Iran Standard Time, 21:18 Arabia Standard Time), an earthquake with a moment magnitude of 7.3 occurred on the Iran–Iraq border, [14] with the Iraqi Kurdish city of Halabja, and the Kurdish dominated places of Ezgeleh, Salas-e Babajani County, Kermanshah province in Iran, [2] [3] [4] [1] [15] closest to the epicentre, 30 kilometres (19 mi) south of the ...
The earthquake ruptured a branch of the Main Recent Fault; a right-lateral strike-slip feature trending northwest. The southern section of the Main Recent Fault from Dorud to Borujerd ruptured during this earthquake. [4] Alongside the 1909 earthquake, events in 1957, 1958 and 2006 are associated with
