During November 16-17, 2015, a rare tornado outbreak produced at least 17 tornadoes in Texas, Oklahoma, and Kansas, including an Enhanced Fujita (EF) EF3 tornado, which damaged a group of engineered structures at an oilfield services facility near Pampa, Texas and nearby engineered center-pivot irrigation system structures. Structural resistances for these structures can be estimated, enabling the estimation of tornado wind speeds associated with the damage. This Rapid Response Research (RAPID) project will investigate tornado wind structure and estimated wind speeds through three-dimensional (3-D), digital data preservation of the tornado damage to the oilfield facility and irrigation system structures. Preservation of this 3-D structural damage data will enable future researchers to validate wind-damage prediction models, via physical modeling, computer modeling, and other predictive damage modeling (for example, loss estimation and risk assessment modeling). Using a suite of remote-sensing data collection methods, the project team will rapidly collect high-resolution, 3-D structural damage data through photography and photogrammetry, laser scanning, unmanned aerial vehicle visual imaging, and satellite imaging. The data collected from this project can serve as the basis for collaborative, multi-disciplinary studies emphasizing the accurate and highly detailed preservation of structural damage from tornadoes, heightened understanding of the complex wind structures of tornadoes, validation or refinement of tornado wind speed estimates, and development of more resilient infrastructure. Undergraduate students will participate in data collection and then use this data to collaborate on future research alongside graduate students and faculty researchers from three institutions, thus training future leaders in the mitigation of natural hazards damage.

2015 年 11 月 16 日至 17 日期间，一场罕见的龙卷风爆发在德克萨斯州、俄克拉荷马州和堪萨斯州产生了至少 17 场龙卷风，其中包括增强型藤田 (EF) EF3 龙卷风，损坏了德克萨斯州潘帕附近油田服务设施的一组工程结构以及附近的工程中心枢轴灌溉系统结构。 可以估计这些结构的结构阻力，从而能够估计与损坏相关的龙卷风风速。 该快速响应研究 (RAPID) 项目将通过龙卷风对油田设施和灌溉系统结构损坏的三维 (3-D) 数字数据保存来研究龙卷风风结构和估计风速。 保存这种 3D 结构损伤数据将使未来的研究人员能够通过物理建模、计算机建模和其他预测损伤模型（例如损失估计和风险评估模型）来验证风害预测模型。 项目团队将利用一套遥感数据采集方法，通过摄影和摄影测量、激光扫描、无人机视觉成像和卫星成像，快速采集高分辨率、3D结构损伤数据。 从该项目收集的数据可以作为协作、多学科研究的基础，强调准确和高度详细地保存龙卷风造成的结构损坏，加深对龙卷风复杂风结构的理解，验证或完善龙卷风风速估计，以及开发更具弹性的基础设施。 本科生将参与数据收集，然后利用这些数据与来自三个机构的研究生和教师研究人员合作开展未来的研究，从而培训减轻自然灾害损害的未来领导者。
