At this site, users can read and view pictures and videos that explain the mechanisms that trigger tsunamis, how they travel across great distances of the ocean, and what damage they cause. Full description.

This is an outline of an earthquakes unit using Seismic/Eruption (called SeisVolE on this webpage). Parts of the unit involve graphing using Excel, and all lessons use the Siesmic/Eruption program (which is available for free download). These lessons cover: making a map using Seismic/Eruption, adding relief to the map, taking a cross-section of the map, importing earthquake data from the USGS PDE ... Full description.
