Undergraduate Studies in Earthquake Information Technology (UseIT) is a mentored summer research program administered by the Southern California Earthquake Center (SCEC) at its lead institution, the University of Southern California (USC). The goal of UseIT is to motivate undergraduates with diverse educational backgrounds towards STEM careers through team-based research in the exciting field of earthquake information technology. UseIT enables undergraduates to participate in interdisciplinary research enabled by high-performance computing (HPC), visualization software, and other IT tools to address grand challenges in earthquake system science. An objective is to close the gap between computer science and geoscience by cross-training students in the modes of understanding distinct to these disciplines. The project particularly seeks to enhance the competency and diversity of the STEM workforce by increasing the research skills and self-confidence of women, under-represented minorities, first-generation college students, and undergraduates from institutions with limited research opportunities, particularly community colleges. UseIT aims to enhance the computational science expertise that SCEC needs to achieve the practical objectives of predicting strong ground motions and understanding earthquake predictability, thus aligning with the NSF's mission of promoting science and advancing nations welfare.Undergraduate Studies in Earthquake Information Technology (UseIT) has matured into a program with an experienced staff and a well-equipped Undergraduate Earthquake Research Laboratory at USC. UseIT's goal of motivating a diverse cadre of undergraduates towards STEM careers is approached by supporting team-based research in the field of earthquake information technology, highly interdisciplinary research enabled by high-performance computing (HPC), visualization software, and other IT tools through which UseIT participants address grand challenges in earthquake system science. SCEC was awarded its first REU-site grant in 2004 and subsequent grants in 2007, 2009 and 2012. The UseIT interns have developed SCEC-VDO, a powerful visualization platform for the 4D display of earthquake information that has seen wide application, e.g., by the Working Group on California Earthquake Probabilities. The UseIT toolkit has expanded in recent years to include geographic information systems (GIS), the OpenSHA hazard-analysis platform, the HAZUS risk-estimation platform, and the physics-based RSQSim rupture simulator. Team-based research on grand challenges with explicit HPC components can demonstrate to students how difficult system-level problems can be solved by using the HPC facilities as precise scientific instruments. This next phase of UseIT incorporates new elements of HPC-enabled research, probabilistic forecasting, and visualization-assisted data analysis of physics-based earthquake rupture simulators to provide probabilistic earthquake forecasts. UseIT received 19,500 node-hours of allocation on the Blue Waters supercomputer, which the students used to run simulated earthquake catalogs hundreds of thousands of years in length, from which they produced time-dependent earthquake forecasts, and the project aims to continue this partnership. UseIT enhances the STEM workforce that SCEC will require to make fundamental progress in earthquake system science.

地震信息技术本科研究 (UseIT) 是一个由南加州地震中心 (SCEC) 及其牵头机构南加州大学 (USC) 管理的夏季指导研究项目。 UseIT 的目标是通过在令人兴奋的地震信息技术领域进行团队研究，激励具有不同教育背景的本科生从事 STEM 职业。 UseIT 使本科生能够参与由高性能计算 (HPC)、可视化软件和其他 IT 工具支持的跨学科研究，以应对地震系统科学的巨大挑战。 一个目标是通过对学生进行交叉培训，使其掌握这些学科不同的理解模式，从而缩小计算机科学和地球科学之间的差距。 该项目特别致力于通过提高女性、代表性不足的少数族裔、第一代大学生以及来自研究机会有限的机构（尤其是社区学院）的本科生的研究技能和自信心，来提高 STEM 劳动力的能力和多样性。 UseIT 旨在增强 SCEC 所需的计算科学专业知识，以实现预测强烈地面运动和了解地震可预测性的实际目标，从而与 NSF 促进科学和促进国家福祉的使命保持一致。地震信息技术 (UseIT) 本科生研究南加州大学的地震研究实验室已发展成为一个拥有经验丰富的员工和设备齐全的本科地震研究实验室的项目。 UseIT 的目标是激励多元化的本科生从事 STEM 职业，其目标是支持地震信息技术领域的团队研究、高性能计算 (HPC)、可视化软件和其他 IT 工具支持的高度跨学科研究。 UseIT 参与者应对地震系统科学中的巨大挑战。 SCEC 于 2004 年获得了第一笔 REU 站点拨款，并于 2007 年、2009 年和 2012 年获得了后续拨款。UseIT 实习生开发了 SCEC-VDO，这是一个用于 4D 显示地震信息的强大可视化平台，已得到广泛应用，例如，加州地震概率工作组。 UseIT 工具包近年来不断扩展，包括地理信息系统 (GIS)、OpenSHA 危险分析平台、HAZUS 风险评估平台和基于物理的 RSQSim 破裂模拟器。 基于团队的针对具有明确 HPC 组件的重大挑战的研究可以向学生展示如何通过使用 HPC 设施作为精确的科学仪器来解决困难的系统级问题。 UseIT 的下一阶段融合了 HPC 支持的研究、概率预测和基于物理的地震破裂模拟器的可视化辅助数据分析的新元素，以提供概率地震预测。 UseIT 在 Blue Waters 超级计算机上获得了 19,500 个节点时的分配，学生们用它来运行数十万年长度的模拟地震目录，并从中生成与时间相关的地震预报，该项目旨在继续这种伙伴关系。 UseIT 增强了 SCEC 在地震系统科学方面取得根本性进展所需的 STEM 劳动力。
