yarndy's video: 6 8 EARTHQUAKE: 4 Very Strong Quakes Strike New Zealand s Puysegur Trench -July 11 2017

A large Earthquake struck offshore near New Zealand causing shaking in Invercargill and Dunedin. Struck just after 7pm on Tuesday, was centred more than 200 kilometres offshore from New Zealand past the Auckland Islands. GeoNet has confirmed the earthquake was magnitude a 6.4. United State Geological Survey (USGS) had initially put the quake at 6.8. *Quantifying potential tsunami hazard in the Puysegur subduction zone, south of New Zealand Studies of subduction zone seismogenesis and tsunami potential, particularly of large subduction zones, have recently seen a resurgence after the great 2004 earthquake and tsunami offshore of Sumatra, yet these global studies have generally neglected the tsunami potential of small subduction zones such as the Puysegur subduction zone, south of New Zealand. Here, we study one such relatively small subduction zone by analysing the historical seismicity over the entire plate boundary region south of New Zealand, using these data to determine the seismic moment deficit of the subduction zone over the past ∼100 yr. Our calculations indicate unreleased moment equivalent to a magnitude Mw 8.3 earthquake, suggesting this subduction zone has the potential to host a great, tsunamigenic event. We model this tsunami hazard and find that a tsunami caused by a great earthquake on the Puysegur subduction zone would pose threats to the coasts of southern and western South Island, New Zealand, Tasmania and southeastern Australia, nearly 2000 km distant. *Link to article - Quantifying potential tsunami hazard in the Puysegur subduction zone, south of New Zealand: https://academic.oup.com/gji/article/183/3/1512/640465/Quantifying-potential-tsunami-hazard-in-the *Link to article - Warning from tsunami research: http://www.stuff.co.nz/southland-times/news/5752087/Warning-from-tsunami-research *More Videos: https://www.youtube.com/user/yarndy/videos ***PLEASE SUBSCRIBE*** Thanks for watching
