9628716 Edwards The coral reefs of western Sumatra offer an opportunity to document the timing, geographic extent and vertical deformations associated with two great historical subjection zone earthquakes and their prehistoric predecessors. Living corals also display evidence for recent submergence, which perhaps represents elastic loading prior t the next great earthquake. This project is a collaborative study of the active tectonics of this subduction zone taking advantage of the details of coseismic vertical changes recorded these corals. Participants include researchers at California Institute of Technology, University of Minnesota, University of California San Diego and Santa Cruz. Results are expected to provide unusually complete information of vertical motions preceeding and caused by large earthquakes in an subduction setting.

苏门答腊岛西部的珊瑚礁提供了一个记录两次历史上的大地震及其史前前身的时间、地理范围和垂直变形的机会。活珊瑚也显示了最近被淹没的证据，这可能代表了下一次大地震之前的弹性载荷。这个项目是对这个俯冲带的活动构造的合作研究，利用了记录这些珊瑚的同震垂直变化的细节。参与者包括加州理工学院、明尼苏达大学、加州大学圣地亚哥分校和圣克鲁斯分校的研究人员。结果有望提供在俯冲环境下大地震之前和引起的垂直运动的异常完整的信息。
