<p>We held 8 regional and topical workshops across the U.S. to gather information for these maps. The maps were available to the public for comment during a 60-day period. A Steering Committee (9 experts) was assembled to review the inputs and results and provide additional insights. The maps have been presented at several professional meetings.</p>
<p> </p>
<p>In this talk we discuss:</p>
<p> </p>
<p>(1) CEUS, (2) WUS (outside California), (3) California, (4) Ground motion models</p>
<p> </p>
<p>We discuss the hazard maps and hazard curves used in the building code. The maps in this presentation are for 2% probability of exceedance in 50 years on a uniform firm rock site condition (V<sup>S30</sup>=760 m/s). Maps are for <strong>0.2 s (5 Hz)</strong> spectral acceleration with 5% damping.</p>
<p> </p>
<p>We consider difference maps (2014-2008) and ratio maps (2014/2008).</p>
