What is an earthquake, scientifically speaking? An earthquake is what happens when the seismic energy from plates slipping past each other rattles the planet's surface. Those seismic waves are like ripples on a pond, the USGS said. The earthquake will be strongest at its epicenter, the point ...

At the Earth's surface, earthquakes manifest themselves by a shaking and sometimes displacement （位移）of the ground. When a large earthquake epicenter （震中）is located offshore, the seabed sometimes suffers sufficient displacement to cause a tsunami（海啸）. The shaking in earthquakes can also ...
Usually, an earthquake is strong enough to cause damage only near its epicenter. However, epicenters at the bottom of the ocean create huge sea waves as tall as 15 meters. These waves cross the ocean in several hours. Rushing toward land, they destroy small islands and ships in their path...
