9632884 Bock 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.

小行星9632884 苏门答腊西部的珊瑚礁提供了一个机会，记录与两次历史上的大地震及其史前前辈有关的时间，地理范围和垂直变形。活珊瑚也显示出最近淹没的证据，这可能代表了下一次大地震之前的弹性负荷。这个项目是利用这些珊瑚记录的同震垂直变化的细节对这个俯冲带的活动构造进行的合作研究。参与者包括加州理工学院、明尼苏达大学、加州圣地亚哥大学和圣克鲁斯大学的研究人员。 预计结果将提供异常完整的信息的垂直运动之前，并在俯冲设置大地震造成的。
