Modern geological and geophysical science depends on acquiring, storing, and analyzing data on computers. Data sets are often many terabytes in size, and computational algorithms can be so complex that they might run continuously for weeks on end. Computers that were last purchased by the geophysics group at the University of Colorado, Boulder dated from before 2011; while these permitted allowing work that was published in over 100 papers, these machines are no longer capable of being updated to currently released operating systems and are far slower than newly available computer systemsmachines. This project award will permit the purchase of a new suite of computers and storage devices that will renew the ability of the scientists in this group to acquire and analyze new and existing datasets in a far more expedient manner. The research conducted by this group includes (but is not limited to) understanding the structure and evolution of continental lithosphere, the location and characterization of earthquakes, seismic hazards associated with oil and gas development, the physics of slow slip at large subduction zones, and exploratory development of tsunami warning algorithms. The new equipment also improves our ability to visualize data and results in more intuitive ways while supporting work from graduate and undergraduate students as well as summer interns affiliated with RESESS (Research Experiences for Community College Students) an REU site funded by NSF under a separate award..This group of researchers represents a coherent unit within the Department of Geological Sciences and CIRES at the University of Colorado Boulder with mutual research interests in seismology, tectonics, geodynamics, and an emphasis on field experiments. The most common needs addressed here include large (10s of terabytes) amounts of storage with highspeed access to a processing core, fast multicore machines for specialized software, a large storage volume that is readily accessible from multiple computers, computers where sophisticated visualizations can be created, and smaller local platforms to accommodate the more routine accessing of processed results, creation of routine graphics and associated writing. The four PIs are actively working on research projects funded by NSF and other funding agencies. Research conducted within this group occurs within the broad themes of seismicity and hazards, continental deformation and structure, and geodynamics. Much of the seismological work requires the collection and analysis of large subsets of data acquired by portable field experiments as well as the Transportable Array component of EarthScope and permanent seismic stations. Other projects require the analysis of continuous datastreams from seismic networks to identify, locate and characterize seismicity in different environments. Other work requires the accumulation and analysis of crystallographic fabrics for comparison with seismological constraints on structures within the deep crust.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

现代地质和地球物理科学取决于获取，存储和分析计算机的数据。 数据集通常是大小的许多trabytes，计算算法可能是如此复杂，以至于它们可能连续数周连续运行。最终由科罗拉多大学的地球物理集团购买的计算机，可追溯到2011年之前；尽管这些允许在100多篇论文中发表的工作允许的工作，但这些机器不再能够更新到当前发布的操作系统，并且比新近可用的计算机SystemsMachines要慢得多。该项目奖将允许购买一套新的计算机和存储设备，这些设备将使该小组中科学家以更加方便的方式获取和分析新的和现有数据集的能力。该小组进行的研究包括（但不限于）了解大陆岩石圈的结构和演变，地震的位置和表征，与石油和天然气开发相关的地震危害，大俯冲区域缓慢滑移的物理学以及海啸警告算法的探索性开发。 The new equipment also improves our ability to visualize data and results in more intuitive ways while supporting work from graduate and undergraduate students as well as summer interns affiliated with RESESS (Research Experiences for Community College Students) an REU site funded by NSF under a separate award..This group of researchers represents a coherent unit within the Department of Geological Sciences and CIRES at the University of Colorado Boulder with mutual research interests in seismology,构造学，地球动力学和对现场实验的重视。这里解决的最常见需求包括大量的存储量（10秒）存储量，高速访问加工核心，快速的多功能机器，用于专用软件，可以从多个计算机，可以创建复杂的可视化的计算机，可以创建复杂的可视化的计算机以及较小的本地平台，以适应更常规的处理程序和相关的图形，并创建相关图形和相关的图形。这四个PI正在积极研究由NSF和其他资助机构资助的研究项目。该组内进行的研究发生在地震性和危害，大陆变形和结构以及地球动力学的广泛主题内。大部分地震学工作都需要在便携式场实验中收集和分析大量数据，以及Earthscope和永久地震站的可运输阵列成分。其他项目需要分析来自地震网络的连续数据流，以识别，定位和表征不同环境中的地震性。其他工作需要对晶体学织物进行积累和分析，以与深层外壳内的结构的地震学限制进行比较。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估评估来支持的。
