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.
An earthquake occurs along a fault at a point called the _____, and the location directly above it at Earth's surface, the epicenter, is what is commonly reported.
The hypocenter, or _____, of an earthquake is the location on the fault where movement is initiated. The _____ is the point on earth's surface directly above the hypocenter.
Earthquakes are felt at the surface of the Earth when energy is released by blocks of rock sliding past each other, i.e. faulting has occurred. Seismic energy thus released travels through the Earth in the form of seismic waves. Most earthquakes occur along active plate boundaries.
Sep 11, 2019 · The shaking or trembling experienced during an earthquake is the result of a rapid release of energy within the Earth, usually as a result of movement along geologic faults. Think back to the strike-slip fault from the Crustal Deformation chapter.
Remind students that earthquakes occur when elastic energy is accumulated slowly within the Earth's crust as a result of plate motions and then released suddenly along fractures in the crust...

Particles of rock move from side to side during the passage of S waves. Because of this, secondary waves cannot travel through liquids, plasma, or gas. When an earthquake occurs at a location in the earth, the body waves radiate outward, passing through the earth and into the rock of the mantle.
