Istanbul is located directly on the North Anatolian Fault, between two tectonic plates. These move apart by two to three centimeters a year, over a length of 1,200 kilometers.

An earthquake with a predicted magnitude of 6 to 7 on the Richter scale would devastate the city. Actress and filmmaker Nisan Arikan witnessed a severe quake in the region when she was nine years old.

How can the city’s 16 million residents prepare for a worst-case scenario?
