Taupo Super Volcano

The Oruanui eruption of New Zealand's Taupo Volcano, the world's most recent supereruption, had a Volcanic Explosivity Index of 8. It is one of the largest eruptions in the history of New Zealand. It occurred about 26,500 years ago in the Late Pleistocene and generated approximately 430 km3 (100 cu mi) of pyroclastic fall deposits, 320 km3 (77 cu mi) of pyroclastic density current (PDC) deposits (mostly ignimbrite) and 420 km3 (100 cu mi) of primary intracaldera material, equivalent to 530 km3 (130 cu mi) of magma, totaling 1,170 km3 (280 cu mi) of total deposits. The eruption is divided into 10 different phases on the basis of nine mappable fall units and a tenth, poorly preserved but volumetrically dominant fall unit.
Modern-day Lake Taupo (616 km2, 238 sq mi in area and 186 m, 610 ft deep) partly fills the caldera generated during this eruption. A 140 km2
 (54 sq mi) structural collapse is concealed beneath Lake Taupo, while 
the lake outline at least partly reflects volcano-tectonic collapse. 
Early eruption phases saw shifting vent positions; development of the 
caldera to its maximum extent (indicated by lithic lag breccias) occurred during phase 10.
