August 2, 2013 – NEW ZEALAND –
An Otago geologist’s draft manuscript suggests there’s a tectonic fault system off the South Island’s east coast potentially comparable in size to the Alpine Fault. University of Otago geologist Phil Ford has privately written a draft proposal, as yet unpublished, and detailing the possibility of the major South Island intra-plate fault, with possible seismic and tsunami hazard implications. His draft uses previous research that identified beach deposits on the coast east of Milton as potential evidence of tsunami relating to the Akatore fault, or another, hitherto unidentified, offshore system. 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. Using New Zealand Institute of Water and Atmospheric Research bathymetric charts, some portions of a fault parallel with the coast were apparent, the paper says. “It is immediately apparent that portions of the suggested system must be covered by South Island river run-off sediment, at least in places, just as the active and earthquake-related fault in the Christchurch area is covered in gravels and other… sediments onshore.” East of Canterbury and Otago the seafloor feature runs south off southeast Southland and down towards northwest of the Auckland Islands. “A strike length of greater than 1000km is clear, more than comparable with the Alpine Fault at about 800km south-southwest of the South Island. Both the southern IFS elements and southern Alpine Fault offshore continuations are clear and readily visible on seafloor bathymetry displays.”
