Research by a team of international scientists in 2006 revealed that the Santorini event was much larger than the original estimate of of dense-rock equivalent ( DRE ) that was published in 1991 . With an estimated DRE in excess of , the volume of ejecta was approximately . If so , the eruption 's Volcanic Explosivity Index was 7 . The volcano ejected up to four times as much as the well-recorded eruption by Krakatoa in 1883 . The Thera volcanic events and subsequent ashfall probably destroyed all indigenous life , as occurred on Krakatoa . Only the Mount Tambora volcanic eruption of 1815 , Mount Samalas eruption of 1257 , Lake Taupo 's Hatepe eruption around 180 CE , and perhaps the Paektu Mountain eruption of 946 CE released more material into the atmosphere during historic times
