What is an Earthquake? - Definition and Components

1. What is an Earthquake? - Definition and Components

Earthquakes are well known for the damage and destruction they leave behind. But what is an earthquake? In this video lesson you will learn about what causes earthquakes and the various components involved in these powerful natural disasters.

The Causes of Earthquakes

2. The Causes of Earthquakes

In this video lesson you will learn what causes earthquakes and where they occur. You will also understand the theory of elastic rebound, and how this relates to movement of the earth's crust.

Identifying and Understanding Earthquakes Using Seismic Activity

3. Identifying and Understanding Earthquakes Using Seismic Activity

Scientists can learn a lot about earthquakes by studying how they move ground. Using seismic activity, we can learn where an earthquake originated as well as how strong it was. In this video lesson, you will learn about seismic activity and how it relates to our understanding of earthquakes.

Aftershocks & Foreshocks of an Earthquake

4. Aftershocks & Foreshocks of an Earthquake

An earthquake is not an isolated event of ground shaking. Foreshocks and aftershocks occur with most earthquakes, and in this video lesson you will learn about them and how they are part of the overall process.

Using the Richter Scale to Measure Earthquakes

5. Using the Richter Scale to Measure Earthquakes

In this video lesson, you will learn about earthquake magnitude and how it is measured. You will also learn how that relates to the amount of energy released during an earthquake, as well as how common different magnitude earthquakes are around the world.

Destruction Caused by Earthquakes

6. Destruction Caused by Earthquakes

Earthquakes are well-known for their damage and destruction, and in this video lesson you will learn about the different types of damage that these dangerous natural disasters can cause.
