The Alpine Fault marks the boundary of the Pacific and Australian Plates. In other words, movement will occur suddenly during an earthquake, rather than gradually. Snow on the mountains of the Pacific plate contrasts with the lower land of the Australian plate. The Australian plate is sliding horizontally towards the north-east, at the same time as the Pacific plate is pushing up, forming the … The Alpine Fault is a geological fault, specifically a right-lateral strike-slip fault, that runs almost the entire length of New Zealand’s South Island. This is a commercial tour run by the local landowner, and visits must be organised in advance. How often does the Alpine Fault rupture? The red line on this map shows our plate boundary (see Module 2). It’s the "on-land" boundary of the Pacific and Australian Plates. Ground shaking will occur from ruptures on these fault lines. You can pick out the line of the Alpine Fault on this satellite image of the South Island. The 2012 paper suggests simply that … It forms a transform boundary between the Pacific Plate and the … Alpine Fault identifies earthquakes in the years 1717, 1620, and 1430, with estimated moment magnitudes of 7.9±0.3, 7.6±0.3, and 7.9±0.4, respectively (Sutherland et al., 2007). The Maruia campsite and car park is about 5 km out of Springs Junction on SH 7 towards Lewis Pass.
