Bingl is one the provinces in Turkey with a very high earthquake risk, since the city center is located on the fault and is very close to the East Anatolian Fault Zone, which is also one of the most important active faults in Turkey. Bingl city center was established on an alluvial filled ground, which further increases the damage potential in case of an earthquake. Imagine that, with the consent of Bingl residents, and by a government decision, Turkey decided to move this city of 170,000 people to 3 km south, to a hilly zone where ground is more resilient to quakes. You are chosen as the program manager of "Establishing Yeni Bingl" endeavor that involves the construction of the new city and migration of the city.
