  <dc:description>&lt;p&gt;&lt;span&gt;An important predictive variable for site amplification is the site dominant frequency (&lt;/span&gt;&lt;span class="inline-formula no-formula-id"&gt;⁠ƒ&lt;sub&gt;d&lt;/sub&gt;⁠&lt;/span&gt;&lt;span&gt;). At seismic monitoring stations, ƒ&lt;/span&gt;&lt;sub&gt;&lt;span class="inline-formula no-formula-id"&gt;d&lt;/span&gt;&lt;/sub&gt;&lt;span&gt;&amp;nbsp;can be calculated from the peak of the horizontal‐to‐vertical spectral ratios (HVSRs) obtained from earthquake recordings (eHVSR). For other sites, ƒ&lt;/span&gt;&lt;sub&gt;&lt;span class="inline-formula no-formula-id"&gt;d&lt;/span&gt;&lt;/sub&gt;&lt;span&gt;&amp;nbsp;can be estimated from microseismic (mHVSR) observations. We compare the ƒ&lt;/span&gt;&lt;sub&gt;&lt;span class="inline-formula no-formula-id"&gt;d&lt;/span&gt;&lt;/sub&gt;&lt;span&gt;&amp;nbsp;values derived from eHVSR (5% damped response spectra from the Next Generation Attenuation‐West2 [NGA‐West2] database;&amp;nbsp;&lt;/span&gt;&lt;a class="link link-ref xref-bibr" data-modal-source-id="rf2"&gt;Ancheta&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;et&amp;nbsp;al.&lt;/i&gt;, 2014&lt;/a&gt;&lt;span&gt;) with those derived from mHVSR (Fourier spectra from&amp;nbsp;&lt;/span&gt;&lt;a class="link link-ref xref-bibr" data-modal-source-id="rf50"&gt;Yong&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;et&amp;nbsp;al.&lt;/i&gt;, 2013&lt;/a&gt;&lt;span&gt;) for seismic stations in California. We show that the logarithm of eHVSR ƒ&lt;/span&gt;&lt;sub&gt;&lt;span class="inline-formula no-formula-id"&gt;d&lt;/span&gt;&lt;/sub&gt;&lt;span&gt;&amp;nbsp;scales linearly with the logarithm of mHVSR ƒ&lt;/span&gt;&lt;span class="inline-formula no-formula-id"&gt;&lt;sub&gt;d&lt;/sub&gt;⁠&lt;/span&gt;&lt;span&gt;, with a standard deviation of&amp;nbsp;&lt;/span&gt;&lt;span class="inline-formula no-formula-id"&gt;0.14log&lt;sub&gt;10&lt;/sub&gt;&lt;/span&gt;&lt;span&gt;&amp;nbsp;units for mHVSR ƒ&lt;/span&gt;&lt;sub&gt;&lt;span class="inline-formula no-formula-id"&gt;d&lt;/span&gt;&lt;/sub&gt;&lt;span&gt;&amp;nbsp;larger than 0.2&amp;nbsp;Hz. The relationship holds for microseismic surveys at distances up to 300&amp;nbsp;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.&lt;/span&gt;&lt;/p&gt;</dc:description>
