(May 2012) Justin Andrew O'Shay, B.S., Texas A&M University Chair of Advisory Committee: Dr. Robert Weiss Dr. David Sparks Earthquake and submarine mass failure are the most frequent causes of tsunami waves. While the process of the tsunami generation by earthquakes is reasonably well understood, the generation of tsunami waves during submarine mass failure is not. Estimates of the energy released during a tsunamigenic earthquake and respec- tive tsunami wave draw a clear picture of the efficiency of the tsunami-generating process. However for submarine landslides, this is not as straightforward because the generation process has never been recorded in nature making energy inferences very difficult. Hence the efficiency of submarine landslide as tsunami generators is yet to be conclusively determined.

Tsunamis Unleashed by Rapidly Warming Arctic Degrade Coastal Landscapes and Communities – Case Study of Nuugaatsiaq, Western Greenland

It triggered a tsunami wave with a runup height exceeding 90 m close to the landslide, ca. 50 m on 15 the opposite shore of the fjord. The tsunami travelled ca. 32 km across the fjord and reached the settlement of Nuugaatsiaq with ca. 1-1.5 m high waves, which were powerful enough to destroy the community infrastructure, impact fragile coastal tundra landscape, and unfortunately, injure several inhabitants and cause 4 deaths. Here we report the results of the field survey of the surroundings of the settlement focused on the perseverance of infrastructure and landscape damages caused by the tsunami, carried out 25 months after the event. 20 1 Introduction Although known to the research community for at least 60 years, the occurrence, scale and impacts of Arctic tsunamis still shock the wider public.

When the sea turns its enormous power against us, our best defense is to get out of its way. But to do that we must first be able to PREDICT when and where the sea will strike.
