Middle school scientists will think you're the coolest teacher on the planet when you use this video to help them understand the basics of plate tectonics. The lyrics, compiled by science teacher Sue Selle, are played to the music from...

Cell phones to crowdsource vibrations to warn of incoming earthquakes? Detectors to register high levels of radon-thoron isotopes? After detailing the factors that make earthquakes so difficult to predict, the narrator of a fascinating...

Take the mystery away from earthquakes. A video lesson explains the theory of plate tectonics and how it relates to earthquakes, volcanoes, mountains, and oceanic trenches. The instructor gives specific feedback on the progression of the...

This clip explains the differences between a hanging wall and a foot wall and how they are used to read a fault line. An animated hiker shows the differences between the two types of walls but doesn't explain how each type effects a...

Quick, full color animation of a thrust fault, or a high-angle reverse fault.

Focal mechanisms are based on the direction of the first arriving P wave. This animation walks the viewer through steps to understand how scientists know what kind of fault motion occurred deep underground. [6:35]

A quick, animated illustration showing a blind thrust fault that does not rupture all the way up to Earth's surface.

Brief animated illustration demonstrating the movement of a horst and graben fault during an earthquake.

Animated illustration demonstrates a normal fault, which is a dip-slip fault where the rock mass above the fault moves down.

An animated illustration of a strike-slip fault. It shows the vertical fracture where the blocks of Earth have moved horizontally.

Brief animation shows friction at an asperity along a right-lateral fault and explains why faults don't keep sliding past each other. [0:13]

Strike-slip faults are vertical fractures where the blocks have mostly moved horizontally. This brief animation provides an illustration. [0:18]

Animation illustrates and explains a transform fault. [0:30]

An asperity is an area on a fault that is stuck or locked. This brief clip illustrates asperities along a strike-slip fault plane. [0:28]

See how to model differential friction along a fault. [2:30]

Find out what causes a fault to move in oblique direction. [0:21]

Find out the motion that is halfway between a normal fault and a strike-slip fault. [0:15]

This demonstration, squeezing uncooked spaghetti noodles in a wood template set in a vise, effectively shows how asperities (stuck patches) on a fault rupture at different times. [1:44]

This animation shows the buildup of stress along the margin of two stuck plates that are trying to slide past one another. [34]

Video lecture demonstrates the use of foam faults to demonstrate faults, and a deck of cards to demonstrate folds and fabrics in rock layers. [5:57]

See how basin and range mountains and valleys form. [1:05]

How do the valleys form in a basin-range province? [0:33]

Visualize how a horizontal fault moves. [0:19]
