Earthquake
The Mw 6.6 earthquake struck near the city of Bingöl, Turkey at 18:44 local time. The depth it struck at varies depending on the agency, but it is agreed to be very shallow. The estimates are between 3 km (1.9 mi) and 10 km (6.2 mi).[2][3] The focal mechanism was likely strike-slip as this earthquake occurred on the East Anatolian Fault. There were two magnitude 5.1 aftershocks on the day of the mainshock.[3] The mainshock ruptured along a 35 km (22 mi) × 12 km (7.5 mi) area of the East Anatolian Fault. A second rupture area measuring 20 km (12 mi) × 12 km (7.5 mi) was detected to the northeast. The two rupture areas produced maximum slips of 60 cm (24 in) and 40 cm (16 in), respectively.[4]
Damage
The earthquake killed at least 755 people and injured 1,200 more.[5] In Bingöl, 90 percent of buildings were destroyed, including the prison and hospital.[6] It caused a total of US$5 million in damage.[2]
