Measure a Changing Volcano part of EarthScope ANGLE:Educational Materials:Resources
This hands-on demonstration illustrates how GPS can be used to measure the inflation and deflation of a volcano. Volcanoes may inflate when magma rises closer to the surface and deflate when the pressure dissipates or after an eruption.
