Earthquake

At 6.7 on the moment magnitude scale, the earthquake was designated as "strong". While the shaking lasted for seven seconds, the maximum Modified Mercalli intensity was officially VIII, and a station near the epicenter recorded IX shaking. The focal mechanism indicated strike slip faulting, and rupture is estimated to have been long with a maximum slip of . More than 3,000 aftershocks rocked the area afterwards.

Aftermath

The quake left at least 498 killed, 2000 injured, collapsed 150 buildings, and damaged over 8000 homes. The provision of housing following the earthquake is now listed by the Chamber of Civil Engineers in Turkey as one of Fifty civil engineering feats in Turkey. A temporary group of 10 seismographs were set up in the area to monitor aftershocks.
