Description:
Students learn to interpret false color satellite images, then compare and contrast images of Mount St. Helens, Washington from 1973, 1983, 1988, 1992, and 1996. They determine a "safe zone of evacuation" for the Mount St. Helens eruption of May 18, 1980, by using NASA Jet Propulsion Laboratory (JPL) DataSlate software to measure the distance from the summit of the volcano to the edge of the ash-covered land. Next, they analyze the rate of recovery of the land devastated by the eruption, by using DataSlate to measure the area destroyed by ash in the 1983 image and comparing it to the 1988, 1992, and 1996 images.
