Iran is an extremely earthquake-prone country. These natural disasters have caused the country tragic loss of life and hundreds of billions of dollars in infrastructure damage. Over time, the Iranian government has implemented some mitigation efforts to limit damage, however, these efforts have not been sufficient, and regulations remain unenforced due to economic turbulence.
What causes earthquakes, and how are they classified?
Earth’s outer shell, the crust, is divided into major “plates”, or large, often irregularly shaped segments of the lithosphere. Underneath the crust is the mantle. This is a heated layer of the earth, with temperatures ranging from 1,000 ºC to 3,700 ºC. Because of these high temperatures, the underside of the earth’s crust, or the plates, are warmed, resulting in them becoming malleable and movable. This movement is often referred to as the plate tectonic theory. During movement, the edges of the plates can hit or slide against one another, which is responsible for the creation of many geographical features such as mountains and oceanic trenches. Unfortunately, despite the wondrous geographic landmarks that have emerged across earth due to the shifting of tectonic plates, destruction may follow.
