  <dc:description>&lt;div id="abstracts" class="Abstracts u-font-serif"&gt;&lt;div id="abs0010" class="abstract author" lang="en"&gt;&lt;div id="abssec0010"&gt;&lt;p id="abspara0010"&gt;Near-surface soil conditions can significantly alter the amplitude and frequency content of incoming ground motions – often with profound consequences for the built environment – and are thus important inputs to any ground-motion prediction. Previous soil-velocity models (SVM) have predicted shear-wave velocity profiles based on the time-averaged shear-wave velocity in the upper 30&amp;nbsp;m (&lt;i&gt;V&lt;/i&gt;&lt;sub&gt;S30&lt;/sub&gt;). This article presents a generic soil-velocity model that accounts both for near-surface conditions (&lt;i&gt;V&lt;/i&gt;&lt;sub&gt;S30&lt;/sub&gt;) and deeper geologic structure, as represented to the depth at which the profile reaches a velocity of 1.0&amp;nbsp;km/s (&lt;i&gt;Z&lt;/i&gt;&lt;sub&gt;&lt;i&gt;1.0&lt;/i&gt;&lt;/sub&gt;). To demonstrate the advantages of our new SVM, we apply it to the Cascadia Region of North America, where numerous geologic basins and glaciated landscapes give rise to a wide range of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;V&lt;/i&gt;&lt;sub&gt;S30&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Z&lt;/i&gt;&lt;sub&gt;&lt;i&gt;1.0&lt;/i&gt;&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;combinations. This soil velocity model yields good estimates of site response across all site conditions, and significantly improves upon a model calibrated using only&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;V&lt;/i&gt;&lt;sub&gt;&lt;i&gt;S30&lt;/i&gt;&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;data. In conjunction with existing models that describe the deep velocity structure of the region (e.g., (Stephenson et al., 2017) [27]; the proposed model is particularly suited for use in regional-scale predictions of site response, liquefaction, landslides, infrastructure damage, and loss. The proposed methodology is broadly applicable to the development of SVMs elsewhere, and with improved understanding of near-surface and deep velocity structures, can facilitate more accurate ground-motion predictions globally.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;ul id="issue-navigation" class="issue-navigation u-margin-s-bottom u-bg-grey1"&gt;&lt;/ul&gt;</dc:description>
