Via the USGS: M 7.3 - 30km SW of Halabjah, Iraq. Excerpt:
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 65x25 km (length x width).
An AP report on news24.com in Cape Town says:
Six people had died and scores more injured, according to the state-run IRNA news agency after a 7.2-magnitude earthquake jolted the region near the border between Iran and Iraq.
The US Geological Survey confirmed the quake on its website, placing its epicenter at around 32km outside the Iraqi city of Halabja, and issuing an "orange" alert for "shaking-related fatalities and economic losses".
The semi-official Iranian ILNA news agency reported that at least 14 provinces had been impacted earthquake.
Iranian social media was abuzz with posts of people evacuating their homes, especially from the cities of Ghasr-e Shirin (near Iraqi border) and Kermanshah.
Faramarz Akbari, Ghasr-e Shirin's governor, said that six people had died and scores more were injured.
Esmail Najar, head of Iran's National Disaster Management Organisation, said "some injured people might be buried under the rubble in Ghasr-e Shirin".
