An earthquake (also known as a quake, tremor or temblor) 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. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to toss people around and destroy whole cities.
An earthquake is a shaking of the ground that occurs when two large blocks of Earth's crust (tectonic plates) slip suddenly past one another. They are the planetâs way of relieving stress in its outer surface and happen because the tectonic plates are in constant motion across the face of the planet.arthquakes can also occur in the middle of tectonic plates for a variety of reasons. Most of these are small, but a few, such as the 1811 and 1812 earthquakes along the New Madrid fault in the Mississippi Valley, are strong enough to cause significant and widespread damage.
