Report GIRS 2021-06: Horizontal-to-Vertical Spectral Ratios from California sites: Open-Source Database and Data Interpretation to Establish Site Parameters

By: Pengfei Wang; Paolo Zimmaro; Tatiana Gospe; Sean K. Ahdi; Alan Yong; Jonathan P. Stewart
DOI: 10.34948/N3KW20

Frequency-dependent horizontal-to-vertical spectral ratios (HVSR) of Fourier amplitudes from three-component recordings can provide information on one or more site resonant frequencies and relative levels of amplification at those frequencies.

San Fernando Earthquake Conference - 50 Years of Lifeline Engineering- Book of Abstracts V1.1_Cover Only.jpg
Report GIRS 2021-05: San Fernando Earthquake Conference- 50 Years of Lifeline Engineering: Book of Abstracts

By: Davis, Craig A., Yu, Kent, and Taciroglu, Ertugrul
DOI: 10.34948/N3QP4X

There has been 50-years of progress in lifeline earthquake engineering since its inception as a primary field of practice following the 1971 San Fernando Earthquake in Los Angeles, California. Over that time lifeline engineering has been applied worldwide and extended to address additional hazards beyond earthquakes.
