Microtremor Horizontal-to-Vertical Spectral Ratio (mHVSR) Data Collection at Tarzana, 2022

El Caballero country club is situated in Tarzana, which is a neighborhood in the San Fernando Valley (SFV) region of Los Angeles, CA. This area experiences seismic activity due to its proximity to the many faults within the SFV. In an effort to better understand the geology and also aid in future site response model development, microtremor Horizontal-to-Vertical Spectral Ratio (mHVSR) surveys were performed specifically near vertical arrays. Collaborative research between the University of Southern California (USC) and the University of California, Los Angeles (UCLA) have performed mHVSR surveys at 15 areas near the golf course area. The HVSR spectra developed using this dataset may be accessed in the United States Community Shear-Wave Velocity (VS) Profile Database (PDB) (https://vspdb.org). This work was supported by the Sonny Astani Department of Civil and Environmental Engineering at the Viterbi School of Engineering, University of Southern California(USC).

埃尔·卡巴列罗乡村俱乐部坐落于美国加利福尼亚州洛杉矶市圣费尔南多谷（San Fernando Valley，简称SFV）的塔扎纳社区。该区域因紧邻圣费尔南多谷内多条活动断层，地震活动频发。为深入解析该区域地质特征，并支撑后续场地响应模型的研发，研究团队在垂直阵列附近开展了微动水平-垂直谱比（microtremor Horizontal-to-Vertical Spectral Ratio，mHVSR）勘测工作。南加州大学（University of Southern California，USC）与加州大学洛杉矶分校（University of California, Los Angeles，UCLA）合作完成了该高尔夫球场周边15个区域的mHVSR勘测。基于本数据集生成的HVSR谱可通过美国社区剪切波速（Shear-Wave Velocity，VS）剖面数据库（PDB，https://vspdb.org）获取。本研究得到南加州大学维特比工程学院Sonny Astani土木与环境工程系的资助。
