9628301 Sieh 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.

9628301 Sieh 苏门答腊岛西部的珊瑚礁提供了记录与历史上两次大地震及其史前前身相关的时间、地理范围和垂直变形的机会。活珊瑚还显示出最近被淹没的证据，这可能代表了下一次大地震之前的弹性载荷。该项目是利用记录这些珊瑚的同震垂直变化的细节对该俯冲带的活动构造进行合作研究。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。 预计结果将提供俯冲环境中大地震之前和引起的垂直运动的异常完整的信息。
