This scorching hot flow spread up to 90 km from the vent and covered all local features except Ruapehu.
it is possible that ash from this eruption was the cause of red sunsets recorded by the Romans and Chinese at that time.99% of the material erupted from Taupo is pumice and ash which has exploded violently to form pyroclastic ash falls and flow deposits.
The improved precision has permitted the first correlations between proximal and distal units; previous correlations with deep-sea ash flows in the western Pacific require major revision.
Plagioclase is one of the most common mineral phases in volcanic rocks; thus, these procedures will be widely applicable to many problems for which precise radiometric age control has not been available.
We studied plagioclase and plagioclase-sanidine concentrates from the oldest and the three largest silicic ash-flow deposits of the Taupo Volcanic Zone, New Zealand, one of the world's largest and most active volcanic systems.
For a one page fact sheet / poster on Taupo Volcano click Volcano Fact Sheets (541.34 k B) Taupo is a ‘supervolcano’ and one of the most frequently active and productive rhyolite caldera in the world.
The huge caldera (collapse crater) has been partly filled by New Zealand’s largest lake, Lake Taupo.
