Earthquakes may be rather dangerous as they are able to destroy cities and to kill thousands of people. Earthquake is the consequence of lithosphere slab shift. It causes the destruction of the earth and it covers with fissures. As earth ruins under the buildings, they fall. But there may be people inside it. In such way millions of people die in drifts. Some people disappear in the mess left by earthquakes and some of them get serious injuries, not to mention about millions of dollars that will need letter for reconstruction of the city, buildings, extra payments for those who suffered in the earthquake, etc.
