Discovering Plate Boundaries is based on 5 world maps containing earthquake, volcano, topography, satellite gravity, and seafloor age data. The novel aspect of the exercise is the "jigsaw" manner in which student groups access the maps and use them to discover, classify, and describe plate boundary types. The exercise is based only on observation and description, which makes it useful at a wide variety ... Full description.

This page offers two pieces of software that produce visualizations of seismicity, volcanic activity and wave propagation. The Seismic Waves program displays waves propagating out from the epicenter simultaneously on three-dimensional and cross-sectional views of the earth. These two views are synchronized with actual event waveforms so that as a particular phase arrives at a seismic station, one ... Full description.
