The Prezi shows Tephra deposited from multiple eruptions in the Taupo volcanic Zone.The history of the area is written in layers of ash revealed in a cutting on Ash Pit road close to Rerewhakaaitu. The Prezi works well on mobiles.
The land and Lakes Field trip document is a good resource and you should flick through it and highlight sections that deal with basalt, rhyollite, the Taupo and Tarawera eruptions. You will come across a section on the road cutting on Ash Pit road.
Skim read to begin with and don’t get bogged down in detail
A useful resource for the Tarawera eruption.
The Okataina Volcanic Complex
Read the PDF file for information about the eruption around 1314. The research document talks about a Plinian eruption (like Vesuvius). Plinian eruptions send huge volumes of ash into the stratosphere and this can have global implications. Individual ash deposits show a fine grained layer at the top idicating that the eruption faded after the initial explosive event
The onset of the Great Famine coincided with the end of the Medieval Warm Period. Between 1310 and 1330, northern Europe saw some of the worst and most sustained periods of bad weather in the entire Middle Ages, characterized by severe winters and rainy and cold summers. The Great Famine may have been precipitated by a volcanic event, perhaps that of Mount Tarawera, New Zealand, which lasted about five years. (Wikipedia)
