Proposing to name it as the Indiania Fault System (IFS), he says it appears to run for most of the offshore length of the South Island, similar in size to the Alpine Fault. Analysis of tree ring patterns in 2018 suggested it happened in 1717, prior to European settlement when there were few people in the South Island. Thomas Arnold was visiting Frederick Weld at Flaxbourne and reported being woken up as his bed shook violently from side to side. The rapid uplift also means that faulted rock from deep down has been brought to the surface, and can be studied by scientists.

Many fault lines cut the ground’s surface in New Zealand; each past fault movement would have been accompanied by a large earthquake. The first European settlers in the Awatere region had just started to make themselves at home when an estimated magnitude 7.1 earthquake woke them at 1.40am on Monday 16 October, 1848. About 20 percent of the region’s population live on soils prone to movement during earthquakes. When tectonic forces overcome this locking, the fault slips, jumping up to a distance of 8 metres at a time. Interactive map of the Alpine Fault and links to a virtual field trip, digging trenches to find buried evidence, such as landslides. In the last 12 million years the Southern Alps have been uplifted by an amazing 20 kilometres, and it is only the fast pace of erosion that has kept their highest point below 4000 metres. In between earthquakes, the Alpine Fault is locked. A lot of research is being done to find out about earthquakes in the past (called palaeoseismology), as they may help indicate when to expect one in the future. Holes were drilled for explosives, and when the explosives were set off, a multi-channel seismograph recorded the seismic waves. Horizontal movement of the Alpine Fault is about 30m per 1000 years — very fast by global standards. / Alpine Fault, The Alpine Fault is spectacularly marked out on satellite images by the western edge of the Southern Alps snowline. In the South Island of New Zealand, the boundary between the Australian and Pacific tectonic plates can be seen on land. The Australian plate is sliding horizontally towards the north-east, at the same time as the Pacific plate is pushing up, forming the Southern Alps. It runs as a single structure for over 500 km. This fault has ruptured four times in the past 900 years, each time producing an earthquake of about magnitude 8. Whole forests that have grown back after an earthquake can be dated, too. Other New Zealand universities, GNS Science and overseas scientists are also interested in the Alpine Fault. Geologists say the fluid could be harnessed to generate electricity or heating. The mountains are rising at 7 millimetres a year, but erosion wears them down at a similar rate. Alpine Fault movement.

The path of the Alpine Fault … The way the waves are reflected and transmitted tells much about the rocks and structures near the fault. Researchers are studying the Alpine Fault to investigate past earthquakes, mountain formation and the structure of the Earth’s crust. Recent research (published in 2012) by GNS Science has extended our knowledge of the Alpine fault earthquake record back through the past 8000 years. New Zealand lies directly on the Alpine Fault, which runs almost theentire length of the South Island. / Science Topics Each time it has ruptured, it has also moved vertically, lifting the Southern Alps in the process. Those that are considered likely to move again in the future are called active faults. using GPS to study small movements of nearby minor faults, and to measure growth of the Alps, using seismic data to find out how the many minor earthquakes in the area are linked to minor faults and the main Alpine Fault. These large earthquakes don’t happen very often – the last one was nearly 300 years ago. Transform Boundary – Alpine Fault, South Island, New Zealand.
