Tutorial

 

Earthquakes are disturbances caused when two portions of earth move against each other.  The earth's surface is covered in areas of land that are in constant movement called tectonic plates.  Earthquakes occur more frequently where two tectonic plates meet.

 

Fault Line

A fault line is an area where two sections of earth slide against each other.  

 

Focus

The focus is the area where an earthquake originates below ground.

 

Epicenter

The area on the surface of the earth that is directly above the focus of an earthquake.

Impact on Living Things:

 

Earthquakes can cause massive devastation by toppling buildings, causing avalanches, and landslides.

 

When earthquakes occur on the ocean floor, they can produce waves called tsunamis.  Tsunamis can destroy buildings causing damage to shoreline communities.
