According to the Turkey Earthquake Hazard Map, which was revised and published in 2018, nearly all of Turkey is vulnerable to seismic risk, with two significant fault lines – the East Anatolian Fault zone and the North Anatolian Fault zone – crisscrossing the country.
The North Anatolian Fault, 870 miles (1,400 kilometers) long, runs east to west across the northern half of the country, menacing the major cities of Ankara, the country’s capital, and Istanbul, and threatening the most industrialized section of the country. The East Anatolian Fault, about 620 miles (nearly 1,000 kilometers) in length, runs diagonally across the southeastern part of the country. It covers an area of smaller cities and villages, but millions of people are at risk in the region.
Put it in ur own words tho :)
