It is a region of jungle covered mountain peaks and rural towns and villages. Nevertheless, this perception was later changed during 1982 when El Chichon (Mexico volcano) erupted. Among this advanced research is the iMUSH (Imaging Magma Under St. Helens) project, which uses geophysical imaging techniques along with geochemical-petrological data to create models of the magma systems underneath the entire area.Â, Beyond tectonic activity, the volcano has a more recent claim to fame: It is home to the world's newest glacier, located right in the volcano caldera.
