Great megathrust earthquakes and the tsumanis they generate are among are the greatest threats to populated coastlines worldwide, such as Chile, Sumatra, Alaska, and Cascadia (the regions extending from southern British Columbia into northern California). The risk of catastrophic consequences and the acute need for improved understanding of these events are underscored by the devastation caused by the 11 March 2011 Tohoku-Oki earthquake off northern Japan. While the destruction from these events is acute, they also offer important opportunities to gain new insights into the processes that spawn them. In the wake of the earthquake in Japan, the proponents of this project have been invited to collaborate with Japanese scientists at JAMSTEC (Japan Agency for Marine Earth-science and Technology) to investigate and document the effects of the earthquake offshore. The broader impacts of this program include enhanced international collaboration, and a contribution to instruction at the investigators? respective institutions, but by far the greatest broader impact of this activity is the very high societal relevance of studying these catastrophic events.

特大逆冲地震及其产生的海啸是对智利、苏门答腊岛、阿拉斯加和卡斯卡迪亚（从不列颠哥伦比亚省南部延伸到加利福尼亚州北部的地区）等世界各地人口稠密海岸线的最大威胁。 2011 年 3 月 11 日日本北部海域东北冲地震造成的破坏凸显了灾难性后果的风险以及加强对这些事件的了解的迫切需要。虽然这些事件造成的破坏是严重的，但它们也提供了重要的机会，让我们能够对产生这些事件的过程获得新的见解。日本地震发生后，该项目的支持者受邀与 JAMSTEC（日本海洋地球科学技术机构）的日本科学家合作，调查并记录近海地震的影响。该计划的更广泛影响包括加强国际合作以及对研究人员的指导做出贡献？各自的机构，但迄今为止，这项活动最广泛的影响是研究这些灾难性事件的高度社会相关性。
