At seismic monitoring stations, fd can be calculated from the peak of the horizontal‐to‐vertical spectral ratios (HVSRs) obtained from earthquake recordings (eHVSR). For other sites, fd can be estimated from microseismic (mHVSR) observations. We compare the fd values derived from eHVSR (5% damped response spectra from the Next Generation Attenuation‐West2 NGA‐West2 database; Ancheta et al., 2014) with those derived from mHVSR (Fourier spectra from Yong et al., 2013) for seismic stations in California. We show that the logarithm of eHVSR fd scales linearly with the logarithm of mHVSR fd⁠, with a standard deviation of 0.14log10 units for mHVSR fd larger than 0.2 Hz. The relationship holds for microseismic surveys at distances up to 300 m away from the seismic stations. The results of this study have beneficial implications for the characterization of site response in modern ground‐motion models as well as in building codes.
