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, just inside Iran, in Kermanshah Province, [4] [10] with an epicentre approximately 30 kilometres (19 mi) south of the city of Halabja, Iraqi Kurdistan. [4]

It was felt as far away as Israel and the United Arab Emirates. With at least 540 people killed (530 in Iran and 10 in Iraq) and more than 8,100 injured, as well as many more unaccounted for, [11] [6] [12] it is currently the deadliest earthquake of 2017. [13]

Tectonic setting

The earthquake was located within the Zagros fold and thrust belt, part of the broad and complex zone of continental collision between the Arabian and Eurasian Plates. At this location the relative convergence of the plates is about 26 mm per year. [4] The convergence is quite oblique to the Zagros belt, although it is partitioned into orthogonal dip-slip motion within the active thrust belt and dextral (right lateral) strike-slip motion along the Main Recent Fault to the northeast of the Zagros Mountains.
