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该奖项支持日本促进科学促进学会（JSPS）12个月的学会博士后奖学金，位于日本仙台的Tohoku University灾难控制研究中心（DCRC）的Andrew Moore博士。 Moore博士将与DCRC教授Fumihiko Imamura博士合作，题为“ Sandy Tsunami沉积物的实验建模”。 最近的一些海啸强调了这样一个事实，即海啸通行的最持久记录之一是它留下的沙质碎片。 这些海啸的沉积物通常是科学家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，沉积结构和晶粒大小的模式。 该信息可用于帮助识别史前海啸沉积物，并允许估计海啸中的大小和速度。 该研究涉及在实验室波罐中产生小海啸，并确定波高，波速，粒径和粒子密度的变化如何影响海啸沉积物的特征。 ***
