They examined 130 outcrops on the flanks of the volcano, exposing sequences of pumiceâash hardened into rockâand other pyroclastic material. The volume of ash deposited, and the estimated height of the eruption plume (43 kilometers above sea level) put the eruptionâs magnitude at a minimum of 7 on the volcanic explosivity index (which has a scale of 1 to 8)âmaking it one of the largest known in the Holocene. The eruption, the authors note, was on the scale of the Tambora eruption of 1815, and more powerful than Krakatoa in 1883.
