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.

由于每种数据类型对地球结构的不同方面都很敏感，因此它们往往会产生不同的图像。在这项研究中，研究人员正在对所有可用的地震数据进行反演，以创建满足组合数据集的单一图像。这张最好的图像被用来了解(1)以前的地质事件——尤其是落基山事件——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。第二点是及时的，因为地震学界正着手通过EarthScope的USArray组件来提高美国地震成像的质量。随着USArray数据的可用，这些数据将被纳入其中，以提供更高质量的地震图像。这些研究人员正在开发的软件将整合不同类型的地震数据，并将向社区提供他们创建的图像。
