Well, the U.S. Geological Survey has its own website and it covers these natural hazards! I first found this site when students showed an interest in the floods that were occurring in the northeast, but the U.S. Geological Survey also covers earthquakes, volcanoes, landslides, geomagnetism, and other coastal and marine geological events.
The U.S. Geological Survey has an educational link at the top that offers grade-level materials including lesson plans, videos and animations. I re-visited the site today and was able view time-lapsed animation of Io, Jupiter's moon, in eclipse! This site would be a great place for students to investigate as they study the world around them!
