Earthquake | Definition, Causes, Effects, & Facts | Britannica
Depending on their intensity, earthquakes (specifically, the degree to which they cause the ground's surface to shake) can topple buildings and bridges, rupture gas pipelines and other infrastructure, and trigger landslides, tsunamis, and volcanoes. These phenomena are primarily responsible for deaths and injuries.

Earthquake - Magnitude, Intensity, Effects: The violence of seismic shaking varies considerably over a single affected area.

The Science of Earthquakes | U.S. Geological Survey
An earthquake is what happens when two blocks of the earth suddenly slip past one another.The surface where they slip is called the fault or fault plane.The location below the earth's surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.. Sometimes an earthquake has foreshocks.

What is an earthquake and what causes them to happen?
An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.In California there are two plates - the Pacific Plate …
