Here's a geology project that uses historical seismograph data that you can collect from the comfort of your own computer. You'll use a web interface to a network of seismometers run by the Northern California Earthquake Data Center, at...

A lesson plan for investigating longitudinal waves by use of a Slinky toy. Directions, questions, and applications to seismic waves are provided.

Four animations showing the movements of surface waves and body waves that are created by earthquakes. Includes P, S, Rayleigh, and Love waves.

When an earthquake occurs, seismic shock waves travel out through the earth from the source of the event. The shock waves travel through the earth (body waves), or along the Earth's surface (surface waves), and can be recorded at remote...

This sequence is an introduction to plate tectonics using evidence from topographical maps, earthquake location and depth, and volcano location using the Seismic Explorer model to investigate patterns of earthquake data and to infer the...

Roll over the seismic stations to see earthquake epicenters triangulated. Touch buttons to watch movies of seismic waves.

Informational site provides illustrated tutorial of light reflection. Also discusses the law of reflection.

This illustrated fact sheet shows how S and P waves each travel at varying speeds and therefore arrive at seismic stations at different times.

This site is primarily set up as an outline and is loaded with graphs, maps, and images. It covers a variety of earthquake-related topics, such as what causes earthquakes, fault lines and structures, seismology, a historical look at...

An informative site that explains how and where earthquakes occur and the different types of faults. Contains maps and charts of fault lines, plate edges, and the continental plates. There are other links within the site of related...

Earthquakes can have different affects depending on their location. This week long exercise asks you to build a model house and a special table to shake it on, and see how different soil types can amplify shaking.

This website is a resource for learning about earthquakes. Java animation at this site helps you visually understand the causes of earthquakes.

Students learn about seismology by using a sample seismograph constructed out of common classroom materials. The seismograph creates a seismogram based on vibrations caused by moving a ruler. The students work in groups to represent an...

A list of frequently asked questions about earthquakes. This is a good source for earthquake trivia and separating fact from fiction.

Information about earthquakes including causes and how they are measured.
