Three large tsunamis on the non-subduction, western side of New Zealand over the past 700years

摘要: Abstract The Tasman Sea between Australia and New Zealand is rarely considered as an important source for tsunamis. We review the past 1000 years of unusual events find evidence three (possibly four) large tsunamis, one historical two during period Māori occupation prior to European arrival. Event 1 appears have affected town Westport, on 12th August 1870 2 occurred in South Taranaki Bight 1470 1510 AD although it may extent farther south along Zealand's West Coast. There are currently insufficient data determine whether Coast sites represent a separate event or associated with 2. 3 1320 1450 AD Waikato coast North Island, Zealand. In attempting identify possible tsunamigenic sources these we note importance considering range potential options such complex subduction zone earthquakes slope failure scenarios order better understand threats posed not only by but similar geographical locations around World.
