Definitions and descriptions of a variety of seismic waves such as S, P, Love, and Rayleigh waves, as well as diagrams and speeds.

The different types of earthquake waves are discussed and illustrated. Features geologist video clip.

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

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

Discover why earthquakes happen, how we measure them, and why they only happen on Earth.

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...

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 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...

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...

Content includes background information, are you at risk, and details about what happens before, during, and after a tsunami.
