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.

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

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...
