A 7.3 earthquake stuck 30 kilometers south of Halabjah, Iraq on Saturday, November 11, 2017 at 18:18:17 hours. Halabjah is the capital of Halabja Governorate, located about 240 km (150 mi) northeast of Baghdad and 14 km (9 mi) from the Iranian border.
About 450 people were killed and close to 8,000 injured when the quake hit near the Iran-Iraq border.
The November 12, 2017 M 7.3 earthquake near the Iran-Iraq border in northwest Iran (220 km northeast of Baghdad, Iraq) occurred as the result of oblique-thrust faulting at mid-crustal depth (~25 km). Preliminary focal mechanism solutions for the event indicate rupture occurred on a fault dipping shallowly to the east-northeast, or on a fault dipping steeply to the southwest.
At the location of this earthquake, the Arabia plate is moving towards the north with respect to Eurasia at a rate of about 26 mm/yr. The two plates converge along a northwest-striking plate boundary in the general vicinity of this earthquake, driving the uplift of the Zagros mountains in Iran. The location of the event and the shallow, northeast-dipping plane of the focal mechanism solution are consistent with rupture of a plate boundary related structure in this region.
While commonly plotted as points on maps, earthquakes of this size are more appropriately described as slip over a larger fault area. Oblique-thrust-faulting events of the size of the November 12th, 2017 earthquake are typically about 65×25 km (length x width).
