Collaborative Research: The Cenozoic history of the Western U.S. - a data integration strategy for Earthscope.

有各种地震数据可用于成像与美国西部相关的结构。由于每种数据类型对地球结构的不同方面敏感，它们往往会产生不同的图像。这项研究中的研究人员正在反演所有可用的地震数据，以创建满足组合数据集的单一图像。这张尽可能好的图像被用来了解(1)以前的地质事件--特别是落基山脉事件--如何继续影响美国西部的构造活动，以及(2)哪里迫切需要额外的地震数据。这第二点是及时的，因为地震学社区正在进行一项重大努力，以改善美国使用EarthScope的USArray组件进行的地震成像质量。随着US阵列数据的出现，这些数据将被包括在内，以提供更高质量的地震图像。这些调查人员正在开发的整合不同类型地震数据的软件将向社区提供，他们创建的图像也是如此。

A variety of seismic data is available to image the structure associated with the western U.S. Because each data type is sensitive to different aspects of Earth structure, they tend to produce different images. The investigators in this study are inverting all available seismic data to create a single image that satisfies the combined data set. This best-possible image is being used to understand (1) how previous geologic events - especially the Rocky Mountain event - continue to influence western U.S. tectonic activity, and (2) where there is a critical need for additional seismic data. This second point is timely as the seismology community embarks on a major effort to improve the quality of seismic imaging under the U.S. with the USArray component of EarthScope. As USArray data become available, these data will be included to provide an improved quality of seismic image. Software being developed by these investigators to integrate different types of seismic data is to be made available to the community, as are the images that they create.
