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

2011年的日本东北大地震和海啸提醒我们，此类事件对生命和财产的危害，以及需要集中科学努力来了解其原因和影响。卡斯卡迪亚从加利福尼亚北部延伸到不列颠哥伦比亚省南部，未来将发生大地震，这将影响到包括西雅图和波特兰在内的许多大城市中心。Cascadia计划是为了更好地了解该地区的地震活动，包括在陆上和海上部署一系列仪器。还计划或正在进行若干辅助研究；其中一项研究是在华盛顿海岸进行的一项复杂的3D（三维）地震调查。该项目获得的2D地震剖面将为规划和实施3D勘探提供必要的数据。这项研究的主要广泛影响是提高对该地区地震风险的了解具有很高的社会意义。

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.
