What Is the Effect of a Large Earthquake?

There have already been several aftershocks following the current earthquake. Scientists are expecting it to follow the same trend as the previous big one in the region. That means there might be more aftershocks going on for quite a long time. A tremor of 2.5 or less usually can't be felt but can be detected by instruments. The Turkish earthquake at 7.8 is classified as major and usually causes serious damage. Anything above 8 causes catastrophic damage and can totally destroy communities at its center.
