Electronic Supplement to: Investigation of Earthquake Site Response in the Gulf and Atlantic Coastal Plains

This repository contains the electronic supplementary materials associated with the report Investigation of Earthquake Site Response in the Gulf and Atlantic Coastal Plains. The materials include (1) project data used in performing site response analyses, and (2) Appendix A materials containing interactive HTML maps and presentation slides summarizing the work. The project_data folder provides the geometric boundary definitions used in the study, the ground motion database (events, records, and stations), shear-wave velocity profiles by geologic group with modified depth-dependent logarithmic standard deviations, statistics of site amplification factors (SAFs), and additional calculated spectral outputs for rock, including rock FAS and rock SA from two approaches across a wide range of frequencies. The appendix_A folder contains interactive maps of event terms and site terms (at 1 Hz and 10 Hz) that are based on residuals defined by FAS and PDFs of presentation slides showing figures in addition to those in the report. These data support the analysis and results presented in the report and can be used by researchers studying earthquake site response, site amplification factors, or the development of ground motion models in the Gulf and Atlantic Coastal Plains. Detailed documentation of file contents, sources, and licensing is included in the accompanying README file within the repository.本仓库包含与《墨西哥湾与大西洋沿海平原地震场地响应研究》(Investigation of Earthquake Site Response in the Gulf and Atlantic Coastal Plains)报告配套的电子补充材料。该补充材料包含两部分：(1) 用于开展场地响应分析的项目数据；(2) 附录A材料，内含交互式HTML地图与总结该研究工作的演示幻灯片。 project_data（项目数据）文件夹收录了本研究使用的几何边界定义、地震动数据库（涵盖事件、记录与台站信息）、按地质群组划分的剪切波速剖面（shear-wave velocity profiles，其标准差采用修正后的深度依赖对数形式）、场地放大因子（Site Amplification Factors, SAFs）统计量，以及针对基岩的额外计算频谱输出，包括基于两种方法在宽频率范围内得到的基岩傅里叶振幅谱（Fourier Amplitude Spectra, FAS）与基岩反应谱（Spectral Acceleration, SA）。appendix_A（附录A）文件夹包含基于傅里叶振幅谱残差定义的事件项与场地项（覆盖1Hz与10Hz频段）的交互式地图，以及用于展示报告未收录图表的演示幻灯片概率密度函数（Probability Density Functions, PDFs）。 本数据集可为报告中呈现的分析与结果提供支撑，可供研究墨西哥湾与大西洋沿海平原地震场地响应、场地放大因子或地震动模型开发的科研人员使用。仓库附带的README文件中，详细说明了各文件的内容、来源与授权许可信息。
