the earthquakes
I am going to talk about earthquakes, earthquakes are natural vibrations of the ground caused by movement along gigantic fractures in earth"s, also caused by volcanic eruptions. Sometimes earthquake can killed more than 100,000 people. Most earthquakes occur when rocks fracture, or break deep within earth. For example when the plates deform it causes the Earth to get fracture and cause earthquakes to develop.
