Ruapehu eruption, July 1996

During the 1995–96 eruptions of Ruapehu, tephra was produced by the rise and explosive expansion of hot gas through molten andesite lava. This video clip shows gas explosions ripping apart the andesite and ejecting bombs and ash. Ash was spread by the wind over most parts of the central North Island.
