Students examine satellite images of an island before and after a volcanic eruption to determine the impact of the eruption.

Learn about volcanic ash and watch a visualization of the Calbuco volcano to see how ash travels around the world. 

Students categorize causes, effects, and responses to volcanic hazards through an Earth system perspective. They use remotely sensed images to examine the visible effects of the eruption of Mount St. Helens in 1980 and identify a buffer zone for safer locations for development.

Students will describe the changes in a newly-formed volcanic island over the first three years of its life.  

Review this page to learn about the background of volcanoes and their eruptions.
