Kauffmann was part of the group aboard Phoenix, a White Island Tours vessel, and he videoed much of the island tour. Whakaari/White Island is the summit of a complex submarine volcano. A phreatic eruption involves therelease of steam and volcanic gases which caused an explosion, launching rock and ash 3km into the air. The processes preceding the explosions are typically localized in areas that are much smaller than the spacing between monitoring instruments. Volcanologists with GNS Science, a New Zealand-based consulting group, spotted some localized surface deformation a few weeks earlier, says Geoff Kilgour, a scientist with the group. Wilson said the regular release of nutrients in the chemicals from the island could help the marine ecosystem in its surrounding shallow waters thrive, and that the eruption may actually prove beneficial in the way that bushfires can aid forest regrowth.

YellowstoneCalderaChronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. Dr Laura Revell, an atmospheric chemist at the University of Canterbury, said volcanoes such as White Island generally produce sulphur dioxide that can form atmospheric aerosol particles of fine dust or droplets of liquid suspended in the air. But the flying rocks, wet debris jets, and scorching air can also cause life-threatening harm. 23 people were rescued from the island.

What factors influence the effects and response to tectonic activity? Past testing of residues from this type of eruption has found them to consist mostly of fine fragments of pulverised rock coated in sulphur and acid salts, which turn into concentrated droplets of sulphuric acid when they come into contact with air, water or human skin. In addition to shooting volcanic ash into the atmosphere, an explosive eruption can create an avalanche of ash, volcanic gases, and rock, called a pyroclastic flow.
