An earthquake is when two blocks of the earth slip past each other. Where they slip past
each other is called the fault of fault plane. The location below the earth’s center is called
the hypocenter while the location on top is called the epicenter.

This article discusses the ins and out of earthquakes. It also explains the history and
details of the Richter scale. In addition, the article details the magnitude of earthquakes
and the strength that they have to cause tsunamis.

To record the earthquakes, scientists use a device called a seismograph. The zig-zag lines
show the strength of different seismic waves. With these lines, scientists use the Richter
scale to determine the devastation of the earthquake.

This video uses animations to show what the earth is made up of and what happens when
earthquakes occur. It shows how the earth’s crust is made of plates and that they move in
different directions. The video also shows some of the most popular earthquake sites
since they are at the plate boundaries.
