Earthquakes
Earthquakes are the shaking of the Earth’s surface. They can range from weak to violent and can cause widespread damage. They are caused by the sudden movement of rock materials below the Earth’s surface. The point inside the Earth where the earthquake starts is called the focus, or hypocenter. The point on the surface of the Earth directly above the focus is called the epicenter.
Earthquakes can cause a variety of damage. They can cause buildings to collapse, bridges to fall, and roads to buckle. They can also cause landslides, tsunamis, and fires. Earthquakes can be a major hazard. However, there are things that can be done to reduce the risk of damage. Buildings can be designed to withstand earthquakes. Early warning systems can be used to warn people of an impending earthquake. And people can be educated about what to do in an earthquake.
