An earthquake is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth’s lithosphere that creates seismic waves. Their strength can range from ones that even can’t be noticed, to large ones that can destroy whole cities. At the Earth’s surface, earthquakes manifest themselves by shaking and sometimes displacement of the ground. If this happens in the ocean, the seizmic waves can cause a tsunami. Also, earthquakes can trigger landslides and volcanic activity. Earthquakes are known for being dangerous and scary. Read about the world’s most terrifying earthquakes that have ever happened!
