Where are earthquakes usailly located?
The same places as volcanoes, on the coasts of countries and near plates
If such pattern does exist could you use it to determine where high risk earthquakes zones are located?
California is located in a geologically active area where two of Earth's tectonic plates slide past each other. This movement builds up tension that is released in the form of earthquakes. Illinois is located in the middle of the North American plate, in an area that has been stable and relatively inactive for hundreds of millions of years, making earthquakes rare.
