If you'd permit me, I will give you my version of your paragraph. Hope this helps.
Almost every year, Turkey is shaken by severe earthquakes. The central Anatolian Fault Line, lying diagonally along the northern part of the country, is one of the most active in the world. These earthquakes cause a lot of death and destruction not just because of their severity but also because many cities and highways have been built over it: an unfortunate consequence of ignorant regional planning. In August 1999, 20,000 people lost their lives and millions of dollars of damage was caused by one of the worst quakes in history. In recent years, some early warning systems have been developed but only to provide 10 seconds of warning before the quake. If there was an well-organized rescue plan in place it may help to at least lower the death toll caused by these earthquakes.
