The isochrone concept is an integral aspect of the age-elevation method, but the latter implicitly assumes that all isochrones are horizontal. Orogen-scale anticline revealed in the Southern Alps of New Zealand by structural thermochronologyДЄ dense set of cooling ages from the Southern Alps reveals an orogen-scale anticline of cooling-age isosurfaces (isochrones) and provides an interesting example of structural thermochronology, where isochrones are used as structural markers. The seismicity is clustered and scattered and a previously observed seismic gap between the Wanganui and Whataroa rivers is also identified. Using almost 8 years of seismic data we calculated about 9,000 preliminary earthquake. We used an automatic phase-picking method for both P- and S- wave arrivals (kPick Rawles and Thurber, 2015). To generate a spatially and temporally continuous catalogue of seismicity in New Zealand's central Southern Alps, we used automatic detection and phase-picking methods. WIZARD, ALFA08, DFDP-10) we are able to extend the region covered. Furthermore, by using data from other temporary networks (e.g. The continuity and density of the Southern Alps Microearthquake Borehole Array (SAMBA deployed in late 2008) allows us to study seismicity in the Southern Alps over a more extended time period than has ever been done previously. Areas of low seismic activity, like the central part of the Alpine Fault, require data recorded over a long duration to reveal temporal and spatial seismicity patterns and provide a better understanding for the processes controlling seismogenesis. Thus, compiling a micro-earthquake catalogue for the Southern Alps prior to an expected major earthquake is of great interest. This low magnitude seismicity, often below the completeness level of the GeoNet national seismic catalogue, may inform us of changes in fault character along-strike and might be used for rupture simulations and hazard planning. Despite this, the Alpine Fault displays low levels of contemporary seismic activity, with little documented on-fault seismicity. The Alpine Fault is one of the most prominent tectonic features in the South Island, New Zealand, and is inferred to be late in its seismic cycle of M 8 earthquakes based on paleoseismological evidence.

Michailos, Konstantinos Townend, John Savage, Martha Chamberlain, Calum The remote and spectacular Fiordland NationalД¬ontinuous micro-earthquake catalogue of the central Southern Alps, New Zealand Further to the south is the prominent 'S' shape of Lake Wakatipu, 83 kilometers long, on the northern shore of which is Queenstown, the principal resort town of the island.

Further to the south in adjacent valleys you can easily see Lakes Hawea and Wanaka, between which (though not visible here) is the Haast Pass Road, the most southerly of the few links between the east and west coast road systems. Cook (to the right in these images), the glacial pale-blue water of Lake Pukaki stands out. From the high peaks, glaciers have gouged long, slender mountain lakes and coastal fiords. Its snow-covered peak is visible to the left of center in each of these MISR images. The tallest mountain in the Southern Alps is Mt. To facilitate stereoscopic viewing, both images have been oriented with north at the left. Viewing the anaglyph in 3-D requires the use of red/blue glasses with the red filter over your left eye. The lower image is a stereo anaglyph generated from the instrument's 46-degree and 26-degree forward-viewing cameras, and is presented at 275-meter per pixel resolution to show the portion of the image containing the Southern Alps in greater detail. It is presented at a resolution of 550 meters per pixel. The upper image is a natural color view from the instrument's vertical-viewing (nadir) camera. This pair of MISR images is from Ap(Terra orbit 1712). The drier eastern seaboard is home to the majority of the island's population. Westerly winds bring clouds that drop over 500 centimeters of rain annually on luxuriant rain forest along the west coast. The higher peaks are snow-covered all year round. The mountains are often obscured by clouds, which is probably why the Maoris called New Zealand 'Aotearoa', the long white cloud. The rugged Southern Alps extend some 650 kilometers along the western side of New Zealand's South Island. 3D glasses are necessary to view this image. This anaglyph from the MISR instrument aboard NASA Terra spacecraft shows the rugged Southern Alps extending some 650 kilometers along the western side of New Zealand South Island.
