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，这些事件对生命和财产造成的危害，以及需要集中科学努力了解其原因和影响。卡斯卡迪亚从北方加州延伸到不列颠哥伦比亚省南部，将是未来大地震的发生地，这场地震将影响一些大的大都市中心，包括西雅图和波特兰。卡斯卡迪亚倡议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。几项辅助研究也正在计划或正在进行中;其中一项研究是在华盛顿海岸附近进行的复杂的3D（三维）地震勘探。该项目将获得的一套二维地震剖面图将为规划和开展三维勘测提供必要的数据。这项研究的主要广泛影响是获得对该地区地震风险的更好理解的非常高的社会相关性。

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.
