		The origin of the Alpine fault is located in the transition area between Fiordland and the Southern Alps on the South Island of New Zealand near Milford Sound.
		While earthquake monitoring on the Alpine fault is not as dense as on the San Andreas, records show that earthquakes of magnitude 3 occur quite frequently, but not in the central portion of the fault.
		One indication that things have not always been quite so calm on the Alpine fault is the presence of a rock type called psuedotachylite, which is thought to form either during an earthquake or with a meteor impact.

	What we do.The Active Earth : Earthquakes FAQ
		Geologists believe that if a fault shows evidence of having moved at least once in the past 100,000 years, it should be regarded as a potential source of earthquakes.
		Once a major fault has formed, future earthquakes are generated along the same line, and after hundreds of thousands or million of years of movement, increasingly large vertical and horizontal separations of land occur.
		The Alpine Fault, which runs for about 600km up the spine of the South Island, is one of the world’s major geological features.

	The Alpine Fault
		The alpine fault runs to the west of the Southern alps, which are pushed up by the fault movements.
		The central part of the alpine fault has very thick crust, about 45km, and this "crustal root" is thickest under the high peaks of Tasman and Cook.
		The fluid in the alpine fault under the central peaks is high pressure water, not molten rock.It was identified from its sound reflection and transmission properties.

	Alpine Fault, New Zealand
		The Alpine Fault is the dominant structure defining the Australian-Pacific plate boundary in the South Island of New Zealand.
		The subduction zone in the north is linked to the subduction zone in the south by a series of very large faults that run through Marlborough (Marlborough Fault System) and down the west coast of South Island (Alpine Fault).
		This compressional movement is causing the Southern Alps to be uplifted at a rate of approximately 7 millimetres per year forming a high elongate mountain range parallel to the Alpine Fault.

		In the case of the Alpine Fault, this had been done by a combination of fault trenching, radiocarbon dating, tree-ring analysis, the study of lichens and contemporary earthquakes, statistical analysis, and highly accuarte measurements of the deformation at the Earth's surface using global positioning satellite technology.
		Further north the fault becomes progressively less active as movement is transferred onto the numerous faults in Marlborough.
		Dr Berryman said when the next rupture occurred on the Alpine Fault ground-shaking intensities were expected to be less on the South Island's east coast, but throughout most of the South Island the next earthquake on this fault would be stronger than any jolt experienced there in the past 100 years.

		The fault bounds the Clan Alpine Mountains on the west and the Edwards Creek Valley on the east (Fig.
		3) on the main fault and a largely buried (<3 m high) antithetic fault scarp 1.6 km toward the center of the basin.
		The antithetic fault records more events in the past 130,000 years than the larger, main fault; thus, the antithetic fault may be a transitional, intravalley link between the southern part of the east-dipping CAF and the northern part of the west-dipping Desatoya fault that forms the eastern margin of the Edwards Creek Valley.

		"One of the issues that makes the Alpine fault interesting is that while it is a strike slip fault for most of its length, it begins in a transition from a subduction zone to a strike slip fault," says Dr. Kevin Furlong, professor of geosciences.
		Perhaps the fresh edge of the plate that joins the fault is rough and that is the reason for the melting during earthquakes."

	Inaugural lecture: Professor Richard Norris
		Most of the movement on the fault however is due to the two plates slipping sideways, with the Australian plate moving northeastwards relative to the Pacific plate.
		Thus the fault is currently accommodating between 70 and 80% of the fault-parallel component of plate motion, but a variable amount of the convergence between the two plates.
		Not only is the Alpine Fault a major earthquake hazard, but so are the myriads of smaller faults east of the Main Divide which collectively accommodate the balance of the plate motion.

		Near Lake Wakatipu, on the east side of the southern Alpine fault zone, is the offset portion of the Red Hill block.
		In contrast with South Island, the crust of North Island is being stretched and lava reaches the surface at aligned active volcanoes such as Ruapehu and Tongariro; White Island (with plume) is the northernmost subaerial volcano of the line and Lake Taupo is a volcanic crater lake.

		As seen by Landsat (Figure T-58.2), the Alpine fault is defined by abrupt truncation of mountain spurs against the Westland plains.

		The fault is extremely distinct in the topographic pattern, nearly slicing this scene in half lengthwise.
		In a regional context, the Alpine fault is part of a system of faults that connects a west dipping subduction zone to the northeast with an east dipping subduction zone to the southwest, both of which occur along the juncture of the Indo-Australian and Pacific tectonic plates.
		But convergence also occurs across the fault, and this causes the continued uplift of the Southern Alps, New Zealand's largest mountain range, along the southeast side of the fault.

		An overdue alpine fault earthquake will strike “out of the blue” and cause widespread death, shut down power generators, create tsunami within New Zealand and overwhelm emergency services, experts warn.
		The major quake will cause intense shaking and rupturing along hundreds of kilometres of the fault line bisecting the South Island, geology experts Tim Davies and Mauri McSaveney predict. The most likely time [for the quake] is now.
		The country had experienced tsunamis in the past, but modern shoreline development has made it much more vulnerable, according to GNS expert Kelvin Berryman.If warnings and evacuations were not carried out in time, an estimated 5000 people would be killed by waves up to 8m high on the east coasts of New Zealand.

		Most of the tremors jolting California are due to sudden increments of movement along the San Andreas fault, which is an example of a major continental strike-slip fault zone.
		Strike-slip faults also cut oceanic lithosphere, in particular along ocean ridges, but because oceanic strike-slip fault zones are hidden by the sea, they are not as well known as their continental kin.
		Specifically, we examine the structure and kinematics of various types of strike-slip faults (both oceanic and continental), the geometry of the subsidiary structures that form in association with these faults, and the tectonic settings in which they occur.

	Transpressive ductile flow and oblique ramping of lower crust in a two-sided orogen: Insight from quartz grain-shape ...
		The three-dimensional (3-D) grain-shape fabric (GSF) of deformed quartz veins was measured in 30 samples from the hanging wall of the oblique-slip Alpine fault in the central Southern Alps, New Zealand.
		Deformation was nonsteady state: transpression was followed by near-vertical shearing as the rocks negotiated the oblique footwall ramp of the Alpine fault.
		Similarities between the model predictions and the observed fabrics suggest that lower crustal flow in the Pacific Plate mimicked the geodetic velocity pattern at the surface today, with obliquely convergent deformation being distributed across a wide region to the east of the Alpine fault.

		(The east-over-west (Pacific over Indo-Australian) plate convergence generally occurs south of the South Island.) The Alpine fault is the major strand of this fault system along most of the length of the island, near and generally paralleling the west coast.
		Its impact upon the topography is unmistakable, forming an extremely sharp and straight northwest boundary to New Zealand's tallest mountains, the Southern Alps.
		Although offsets on the Alpine fault are generally right-lateral (35-40 millimeters per year) and thus consistent with the offset in the subduction zone pattern, vertical offsets (about 7 millimeters per year) are likewise consistent with the uplift of the Southern Alps.
