The Andaman-Sumatra margin of Southeast Asia is the site of convergence between the floor of the Indian Ocean and the Asian continent that spawns major earthquakes and tsunamis, with consequent loss of both lives and property. An interesting feature of this boundary is that the plate motion changes from normal convergence (perpendicular to the plate boundary) at Sumatra to oblique (parallel to the boundary) in the Andaman Sea. This project seeks to unravel how the displacement is partitioned between these directions, which is crucial to understanding the tectonics of this region. An additional and very significant benefit of the work is that build on and improve a rare collaboration between U.S. investigators and the Indian National Institute of Oceanography.

东南亚的安达曼-苏门答腊边缘是印度洋海底和亚洲大陆的交汇点，产生大地震和海啸，造成生命和财产损失。这个边界的一个有趣的特征是，板块运动从苏门答腊的正常会聚（垂直于板块边界）到安达曼海的倾斜（平行于边界）。该项目旨在揭示这些方向之间的位移是如何分配的，这对于理解该地区的构造至关重要。这项工作的另一个非常重要的好处是，建立和改善了美国调查人员与印度国家海洋研究所之间的罕见合作。
