The project is focused on studying the relationship between stress evolution of the Pacific-North American plate boundary and the occurrence of major earthquakes in this region using time-dependent fault deformation models constrained by geologic, geodetic, and paleoseismic data. EarthScope is leading a large-scale community effort to understand the nature of earthquake hazards along the Pacific-North American plate boundary through a growing archive seismic and geodetic instruments. These instruments are now prepared to capture critical details of pending major seismic events, however a 3D synoptic picture of stress evolution spanning the full earthquake cycle requires sophisticated computer models, combined with improved paleoseismic chronologies. To investigate earthquake cycle stress evolution of the plate boundary, this project synthesizes several EarthScope data products with semi-analytic crustal deformation modeling techniques. These efforts include: (1) inclusion of community-defined fault locations and geometries, (2) integration of EarthScope InSAR and Plate Boundary Observatory GPS data, (3) analysis of new paleoseismic faulting histories, and (4) exploration of new fault model capabilities. A significant component of this proposed work also aims to develop K-16 educational tools and opportunities for both students and teachers, and to provide pertinent and accessible earthquake information to the general public. This portion of the project emphasizes (1) integration of visualization technologies, EarthScope Internet resources, and Earth science teaching modules for a masters-level Computers in Earth Science course for pre- and in-service K-12 teachers, (2) development of an EarthScope Active Earth kiosk display, highlighting this project's research results, local and regional EarthScope science, and Earth science career stories, and (3) participation of local high school students in the Pathways to the Geosciences summer camp, an ongoing educational program hosted by the University of Texas at El Paso. The fundamental earthquake science and outreach initiatives being explored by this project have substantial societal relevance, as time-dependent earthquake stress simulations will soon be poised to help mitigate seismic hazards and to transform the public's conception and appreciation of large-scale, temporally evolving Earth processes.

该项目的重点是研究太平洋北美板块边界的应力演化与该区域中主要地震发生的关系，使用时间依赖性的断层变形模型受到地质，地球和古呼吸数据的约束。 EarthScope正在领导大规模的社区努力，以通过日益增长的档案地震和地球仪器来理解太平洋北美板块边界沿太平洋北美板块边界的性质。 现在，这些仪器准备捕获未决的重大地震事件的关键细节，但是跨越全地震循环的应力演化的3D概要图片需要复杂的计算机模型，并结合了改进的古sissic时间。 为了研究板边界的地震循环应力演化，该项目通过半分析地壳变形建模技术合成了几种地球数据产物。 这些努力包括：（1）包括社区定义的断层位置和几何形状，（2）Earthscope Insar Insar和板边界观测室GPS数据的整合，（3）分析新的古糖震动断层历史，以及（4）探索新的断层模型功能。 这项拟议工作的重要组成部分还旨在为学生和教师开发K-16的教育工具和机会，并向公众提供相关且易于访问的地震信息。 该项目的这一部分强调（1）可视化技术，地球互联网资源和地球科学教学模块，用于地球科学课程中的大师级计算机，为K-11教师提供的地球科学课程，（2）Earthscope积极的地球亭的发展，突出该项目的研究成果，该项目的研究成果是地球科学的研究，并在地球上的科学和地区的科学研究（3），并在3个地球上的研究，并在3个地球上的研究（3） Geosciences夏令营，由德克萨斯大学埃尔帕索（El Paso）主持的正在进行的教育计划。该项目探索的基本地震科学和外展计划具有很大的社会意义，因为时间依赖于时间依赖的地震压力模拟很快就会有助于减轻地震危害，并改变公众对大型，暂时发展的地球过程的构想和欣赏。
