**Lesson 4-1 Forces in Earth's Crust Investigation** Use this link to do the lesson 4-1 investigation
 * Earthquakes**

**Anatomy of an Earthquake** -Take a journey below the Earth's surface to discover what causes earthquakes. Find out where earthquakes are most likely to take place.

__**Earthquake Fault Animations:**__

**Fault Animations** -Here you can view animations of normal, reverse, and strike slip faults.


 * **Normal Fault** || **Reverse Fault** ||
 * ** Strike-Slip Fault** || **Blind Thrust Fault** ||

__**Animation of Earthquake Waves:**__
 * **Primary Waves**

**(P Waves)** || **Secondary Waves** **(S Waves)**  ||

**Watch P & S waves Moving Through the Earth's Interior** -This animation comes from the same site as the animation above, but this shows these same waves as they travel through the interior of the Earth.

** Changing the Thickness of a Layer** -This animation allows you to compare the paths that P and S waves would take in models of the Earth with liquid cores of different sizes.

**Make Your Own Earthquake** -There are 3 types of seismic waves that occur during an earthquake. Play this activity to discover how **P waves, S waves,** & **Surface waves** all move through the crust in different ways. Be sure to click on the **grid** in the ground structure box to see each type of wave travel separately through the crust!

**Mountain Maker, Earth Shaker** -As we learned in class, the Earth's crust is made up of a series of thick plates that drift atop the soft underlying mantle. In this activity, you can build mountains, trigger volcanoes, and create new sea floor by moving these plates.

**What is the Richter Scale Anyway?** -This site does a great job explaining what the typical effects are that we feel when we experience earthquakes of different magnitudes.

**Plate Action** -This activity explores how plates, earthquakes and volcanoes are related. To play this game, squeeze the sponge to remove Earth's oceans, then drag the scanner and seismic tool over the picture to see where Earth's volcanoes and earthquakes occur. What do you notice?

** The Hot Zones** -This is another site that explores how plate movement causes earthquakes, volcanoes, and mountains to form. There are a number of really good animations in this site to help explain these wonders of the Earth.

**Earthquake Animation**-What happens inside the Earth when an earthquake happens? Click here to find out. This site has some good animations that help us to better understand earthquakes.

**Earth: All Stressed Out** -This step-by-step exploration of what happens during an earthquake features a number of great animations to help us better understand just what goes on during an earthquake.

** Observe What Happens During an Earthquake**-There are 3 films from 3 different security cameras taken during the same earthquake at locations near Seattle, Washington. Watch each clip carefully. Use the time stamps in the lower left corner of each movie to determine when the shaking started and how long it lasted in each location.

**Locating** **Earthquakes** **Rapid Earthquake Viewer** - ** The Rapid Earthquake Viewer (REV) gives you access to data from [|seismograph stations] around the world. REV monitors the earth and posts information about recent [|earthquakes] so you can see where they happened and view the [|seismograms] from global seismograph stations for every [|notable earthquake]. REV even lets you check up on seismograph stations in your area, so if you think you felt the ground shake, check REV! **

**Top Earthquake States** -Which states are the riskiest one's to live in with regards to earthquakes? Click here to find out.

**Latest Quakes**** in the USA** -This site has really great, detailed map of the latest earthquakes that have happened in the U.S. Be sure to click on parts of the map to zoom in!

**Any earthquake activity happen today?** -This site has really great, detailed maps of the earth that show us where recent volcanic and earthquake activity has occurred. This site is updated daily.

**List of Earthquake Times & Locations** -This site gives you a concise listing in chronological order of the latest earthquakes and their locations.
