Its violent eruption, which began on June 6, 1912, and lasted 60 hours, is considered the largest volcanic eruption of the 20th century. NPS photo. Because the tectonic plates move whereas the mantle plume remains in the same place, each volcano becomes dormant after a while and a new volcano is then formed as the plate shifts over the hotspot.
