Moore 9804832 This award supports a 12 month Japan Society for the Promotion of Science (JSPS) Postdoctoral Fellowship for Dr. Andrew Moore at the Disaster Control Research Center (DCRC), Tohoku University in Sendai, Japan. Dr. Moore will work with Dr. Fumihiko Imamura, Professor DCRC, on a research project entitled, "Experimental Modeling of Sandy Tsunami Deposits." Several recent tsunamis have highlighted the fact that one of the most persistent records of the passage of a tsunami is the sandy debris it leaves behind. These tsunami deposits are often the only evidence scientists have that prehistoric tsunamis once struck a coast. The proposed research is designed to determine the general features of tsunami deposits, including overall geometry, sedimentary structures, and grain-size patterns. This information can be used to help identify prehistoric tsunami deposits, and to allow estimation of the size and speed of tsunamis from their deposits. The research involves producing small tsunamis in a laboratory wave tank and determining how changes in wave height, wave velocity, particle size, and particle density affect the features of tsunami deposits. ***

Moore 9804832 该奖项支持 Andrew Moore 博士在日本仙台东北大学灾害控制研究中心 (DCRC) 获得为期 12 个月的日本学术振兴会 (JSPS) 博士后奖学金。 Moore 博士将与 DCRC 教授 Fumihiko Imamura 博士合作开展一项名为“桑迪海啸沉积物实验模拟”的研究项目。 最近发生的几次海啸凸显了这样一个事实：海啸过后最持久的记录之一就是它留下的沙质碎片。 这些海啸沉积物通常是科学家掌握的史前海啸曾经袭击过海岸的唯一证据。 拟议的研究旨在确定海啸沉积物的一般特征，包括整体几何形状、沉积结构和粒度模式。 这些信息可用于帮助识别史前海啸沉积物，并可根据其沉积物估计海啸的规模和速度。 该研究涉及在实验室波浪池中产生小型海啸，并确定波高、波速、颗粒大小和颗粒密度的变化如何影响海啸沉积物的特征。 ***
