9506389 AveLallement This field-based study of the tectonically active area of Attu island in the Aleutian volcanic arc will collect detailed data on recently active brittle fault populations. The goal is to determine how to known oblique convergence across the Aleutian arc is partitioned into strike slip, thrust and extensional faults. The results of this study will significantly improve our understanding of oblique collisional orogens, and will aid in the understanding of active plate-boundary tectonic processes.

这项对阿留申火山弧阿图岛构造活动区的实地研究将收集近期活动的脆性断层群的详细数据。目的是确定如何将阿留申弧上已知的斜向辐合带划分为走滑断层、逆冲断层和伸展断层。这一研究结果将大大提高我们对斜碰撞造山带的认识，并有助于了解活跃的板块边界构造过程。
