The first and most destructive of the 2020 Iran–Turkey earthquakes occurred on 23 February, near Khoy in north-west Iran, close to the border with Turkey, killing 9 people in Başkale, Van.[2] It hit at 9:23 a.m. local time (05:53 UTC) with a magnitude of 5.8 Mw[1] at a depth of 6 kilometres (3.7 miles)[3] and the epicenter was Qotur district, according to the Iranian Seismological Center (IRSC). About 10 hours later the same area was hit by another major earthquake of 6.0 Mw .[4]

Tectonic setting

Northwestern Iran and easternmost Turkey lie within the zone of complex structure associated with the continuing

strike-slip faults, such as the North Tabriz Fault and the Gailatu–Siah Chesh-meh–Khoy Fault. Normal faults are developed at terminations and releasing bends on the strike-slip faults. The entire fault system is active and has been associated with many destructive earthquakes.[5]

Earthquakes

The first of the larger earthquakes had a magnitude of 5.8 Mw  with a depth of 10 km (ANSS),[1] 5.8 ML  with a depth of 8 km (KOERI),[6] or 5.7 mbLg with a depth of 6 km (Iranian Seismological Center (IRSC)).[7] It was followed just over 10 hours later by the second event, which had a magnitude of 6.0 Mw  with a depth of 10 km (ANSS),[4] 5.8 ML  with a depth of 5 km (KOERI),[8] or 5.9 mbLg  with a depth of 12 km (IRSC).[9]

Damage

The area of significant damage stretched from the city of Van in the west to Khoy in Iran to the east. More than 1,000 buildings were destroyed in Turkey,[10] with many others damaged in 43 affected villages in Iran.[11] The Turkish health ministry reported that nine people had died, four of them children,[12] with another 66 injured.[13] 75 people were reported injured in Iran.[11] No further casualties have been reported in Turkey following the Mw  6.0 earthquake.[14] Death toll climbed to 10 when a teenager later died in the hospital.[15]
