This detailed geological map and authoritative text describe and illustrate the volcanic geology of one of the world's most active rhyolite caldera volcanoes. The map covers the area between Rotorua, Waiotapu and Kawerau, including all of the Okataina Volcanic Centre and part of Rotorua Caldera. The Volcanic Centre's stratigraphy, structures, volcanic history, hazards, geothermal resources and drainage are all summarised in the extensive 156 page text. The Okataina Centre is still active, having erupted over 80 cubic kilometres of molten rock in eleven major eruptive episodes during the last 22 000 years. The latest eruption occurred at Tarawera-Rotomahana in 1886 AD and claimed 108 lives.
The sequence of volcanic events described and illustrated in this book and map provide a valuable source of geological-volcanological information for scientists, engineers, regional and territorial authorities, hazard managers and the public.
