Map[edit]

It would be good to include a map like the one by Graeme Stevens, shown here. Avenue 09:24, 29 Dec 2004 (UTC)

Length[edit]

It appears that the Alpine Fault and the Macquarie Fault Zone are extensions of each other, i.e. two different names for the same fault zone. Comment? --Bejnar (talk) 00:20, 28 May 2012 (UTC)[reply]

They're always described separately. The Macquarie Fault Zone originated as a spreading centre and is entirely within oceanic crust, whereas the Alpine Fault is within continental crust. It's not unusual for a plate boundaries to be given different names as the character changes along their lengths - mid-oceanic ridges do it all the time, e.g. the Reykjanes Ridge and the Kolbeinsey Ridge.

Length of faults is challenging, not only as it can change at the next earthquake. I suspect there is some controversy in academic circles as to length of the Alpine Fault after a delve into the literature to try to resolve an unlikely length for the fault quoted in introduction to article but inconsistent to its citation.

Hello! This is a note to let the editors of this article know that File:South Island blizzard 2003.jpg will be appearing as picture of the day on May 17, 2015. You can view and edit the POTD blurb at Template:POTD/2015-05-17. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page. Thanks! — Crisco 1492 (talk) 23:56, 28 April 2015 (UTC)[reply]

Australian Plate[edit]

To be consistent with geology knowledge accumulated in last few decades I have ensured the term Indo-Australian Plate in the article refers to the plate that existed between about 43 to 3 million years ago and the term Australian Plate where the sense relates to current circumstances. Be aware that many textbooks and sources, particularly from last century, but also into early years of this century are incorrect. ChaseKiwi (talk) 18:22, 11 October 2023 (UTC)[reply]


Alpine Fault
Snow delineates the escarpment formed by the Alpine Fault along the Southern Alps' northwest edge, near the west coast of New Zealand's South Island, in a satellite image showing the aftermath of a blizzard that hit the island in July 2003. This geological fault, which forms a transform boundary between the Pacific Plate and the Indo-Australian Plate, has experienced numerous earthquakes over the past millennium, including four which reached magnitude eight on the Richter scale.Photograph: Jacques Descloitres / MODIS Rapid Response Team at NASA/GSFC
