Earthquake is a sudden movement of the Earth's surface. It can cause great damage. It is caused as the tectonic plates of land hit, bump or slide past each other. Earthquake happens all the time; however, most of the time, we don't feel earthquakes as they are too small to reach us. Sometimes, they are so strong that they can be felt over thousands of miles way. When an earthquake happens, we feel vibrations. We can see that objects are shaken and may fall. Earthquakes can give birth to hills, mountains, holes as well as new oceans. On the negative sides, earthquakes can cause fires, tsunamis, landslides or avalanches. When earthquake happens, we should protect ourselves right away to stay safe.
