RAPID: Collaborative Research: A Short, Open-Access 2D MCS Acquisition Program off Washington State

2011年东北大地震和海啸提醒我们注意此类事件对生命和财产的危害，并提醒我们需要有重点的科学努力来了解其原因和影响。卡斯卡迪亚从加利福尼亚州北部延伸到不列颠哥伦比亚省南部，未来将发生一场大地震，影响包括西雅图和波特兰在内的多个大型大都市中心。卡斯卡迪亚倡议是一项努力，旨在更好地了解该区域的地震活动，其中包括部署一系列陆上和近海仪器。几项辅助研究也在计划中或正在进行中；其中一项研究是将在华盛顿海岸进行的复杂的3D(三维)地震调查。该项目将获得的一套二维地震剖面将为规划和进行三维测量提供必要的数据。这项研究的主要更广泛的影响是，对该地区地震风险的更好理解具有很高的社会相关性。

The great Tohoku earthquake and tsunami of 2011 has reminded us of the hazards to life and property that attend such events, and of the need for a focused scientific effort to understand both their causes and effects. Cascadia, which extends from northern California to southern British Columbia, will be the site of a future great earthquake that will affect a number of large metropolitan centers, including Seattle and Portland. The Cascadia Initiative is an effort to gain a better understanding of seismicity in the region that includes the deployment of an array of instruments both onshore and offshore. Several ancillary studies are also planned or under way; one such study is a sophisticated 3D (three dimensional) seismic survey to be carried out off the coast of Washington. The suite of 2D seismic profiles that will be acquired by this project will provide essential data for planning and carrying out the 3D survey. The chief broader impact of this study is the very high societal relevance of gaining an improved understanding of the seismic risk in this region.
