This interdisciplinary workshop will bring together researchers who study tsunamis from different perspectives, such physical and social sciences and engineering, to develop priorities for interdisciplinary research on tsunami deposits, and how this research can be employed to increase awareness of and preparedness for tsunami hazards, as well as help to develop better hazard assessments and mitigation designs. The 2004 Sumatra and 2011 Tohoku earthquakes and their associated ocean-crossing tsunamis underscore the importance of these topics, even in technologically advanced countries. Anticipated outcomes of the workshop include recommendations to NSF on tsunami research priorities and preliminary collaborative NSF proposals.The workshop will be organized around the following questions, which range from basic science to applications in the public sphere:- What causative processes are recorded in deposits and erosional features of tsunamis?- How can geologic information about tsunamis be compared to data collected during modern post-tsunami surveys?- How can tsunami deposit studies be incorporated into engineering designs of marine and coastal infrastructure, and- How can tsunami deposit information be used to increase tsunami hazard awareness and preparedness of communities and individuals?Intellectual MeritTsunamis happen often in the world's oceans, on both human and geologic time scales. Most tsunamis result from fault displacement under the sea; others are set off by submarine landslides, volcanic eruptions, and meteorite impacts. Barely two decades have passed since geologists began using onshore sedimentary deposits to identify areas at risk to tsunamis. The work has produced startling discoveries, particularly in the northwestern United States. But basic questions remain, such as how to distinguish tsunami deposits from storm deposits on coasts with large storm surges. Tsunami deposits also have enormous potential as recorders of flow depth and velocity? parameters of importance to coastal engineers. Working together at this frontier are geologists, sediment-transport experts, numerical tsunami modelers, experimentalists, engineers, and social scientists. The workshop provides a timely venue for these various specialists to weigh priorities and plan collaborations.Broader ImpactsThere are three avenues to addressing tsunami hazard: assessment, mitigation, and warning. One of the major means for assessment is to quantify recurrence intervals and size estimates of past events, and tsunami-deposit studies are an important means for doing so. Moreover, tsunami-deposit studies can help in generating public education and awareness--an important aspect of mitigation efforts. The 26 December 2004 and the 11 March 2011 tsunamis tragically demonstrate the global need for tsunami hazard assessment, education, and community preparation. This workshop will bring together scientific researchers and engineers in order to develop means for improving the communication of tsunami research results to potentially affected communities.

这个跨学科的研讨会将聚集在一起的研究人员，这些研究人员从不同的角度研究海啸，这样的身体和社会科学和工程学，以开发有关海啸矿床的跨学科研究的优先级，以及如何采用这项研究来提高对Tsunami危害的认识和准备，并有助于开发更好的Heabard Issess和MiTigation Interigation Interigation and Mitigity的设计。 2004年的苏门答腊和2011年的Toohoku地震及其相关的海啸都强调了这些主题的重要性，即使在技术发达国家中也是如此。 Anticipated outcomes of the workshop include recommendations to NSF on tsunami research priorities and preliminary collaborative NSF proposals.The workshop will be organized around the following questions, which range from basic science to applications in the public sphere:- What causative processes are recorded in deposits and erosional features of tsunamis?- How can geologic information about tsunamis be compared to data collected during modern海啸后的调查？ - 如何将海啸的存款研究纳入海洋和沿海基础设施的工程设计中，以及 - 如何使用海啸沉积信息来提高海啸危害的认识和对社区的准备和备忘性？知识上的Merittsunamis经常在人类的海洋和地球上发生在世界海洋中。大多数海啸是由于海底的断层位移而导致的。其他人则由海底滑坡，火山喷发和陨石撞击引起。自从地质学家开始使用陆上沉积沉积物来确定对海啸风险的地区以来，只有二十年了。这项工作产生了令人震惊的发现，尤其是在美国西北部。但是仍然存在基本问题，例如如何将海啸沉积物与风暴潮流的风暴沉积物区分开。作为流程深度和速度记录的记录器，海啸沉积物也具有巨大的潜力？对沿海工程师的重要性参数。地质学家，沉积物 - 传输专家，数字海啸建模者，实验家，工程师和社会科学家共同努力。该研讨会为这些各种专家权衡优先事项和计划合作提供了及时的场所。BRODERIMPACTSTHERE是解决海啸危害的三个途径：评估，缓解和警告。评估的主要手段之一是量化过去事件的复发间隔和大小估计，海啸居民研究是这样做的重要手段。此外，海啸居民的研究可以帮助产生公共教育和意识，这是缓解工作的重要方面。 2004年12月26日和2011年3月11日的海啸悲惨地证明了全球对海啸危害评估，教育和社区准备的需求。该研讨会将汇集科学研究人员和工程师，以开发用于改善海啸研究结果与潜在受影响社区的交流的手段。
