The earthquake on August 17, 1999, took more than 14,000 lives.

Cause: this region of Turkey rests above the North Anatolian fault, which is wedged between two huge tectonic plates, Eurasia and Africa/Middle East. As the plates grind against each other they put pressure on the North Anatolian fault, which periodically ruptures.

Casualties: by Monday, August 23, the official crisis center reported 12,148 dead. On Tuesday, August 24, CNN reported more than 14,000 dead and 200,000 homeless.
