NocchiEarth Science with LabSeptember 24, 2018Prominent FaultsThe Alpine Fault is a major strike-slip fault that is about 600km long, almost covering theentire length of New Zealand's South Island. It forms a transform boundary between the PacificPlate and the Indo-Australian Plate. This fault is known to have produced 4 major earthquakesranging from 6 to highest of 8 magnitudes for the past 900 years.These earthquakes don’thappen often but when it does it is always a destructive one.This may be because Alpine Fault is a strike- slip fault and forms transform boundary.The Australian plate and pacific plate moves both horizontally and vertically. The Australianplate slides horizontally towards the north-east, and at the same time, the Pacific plate pushes up,forming the Southern Alps. The horizontal movement along the fault is not smooth, as both sidesare locked together. When tectonic forces overcome this locking, the fault slips, jumping up to a
