  <dc:description>&lt;p&gt;&lt;span class="EXLDetailsDisplayVal"&gt;The &lt;span class="searchword"&gt;Villa&lt;/span&gt; &lt;span class="searchword"&gt;Del&lt;/span&gt; &lt;span class="searchword"&gt;Monte&lt;/span&gt; &lt;span class="searchword"&gt;landslide&lt;/span&gt; was one of 20 &lt;span class="searchword"&gt;large&lt;/span&gt; and complex &lt;span class="searchword"&gt;landslides&lt;/span&gt; &lt;span class="searchword"&gt;triggered&lt;/span&gt; by the &lt;span class="searchword"&gt;1989&lt;/span&gt; &lt;span class="searchword"&gt;Loma&lt;/span&gt;&lt;span class="searchword"&gt;Prieta&lt;/span&gt;, &lt;span class="searchword"&gt;California&lt;/span&gt;, &lt;span class="searchword"&gt;earthquake&lt;/span&gt; in a &lt;span class="searchword"&gt;zone&lt;/span&gt; of pervasive &lt;span class="searchword"&gt;coseismic&lt;/span&gt;ground cracking near the fault rupture. The &lt;span class="searchword"&gt;landslide&lt;/span&gt; was approximately 980 m long, 870 m wide, and encompassed an area of approximately 68 ha. Drilling data suggested that movement may have extended to depths as great as 85 m below the ground surface. Even though the &lt;span class="searchword"&gt;landslide&lt;/span&gt; moved &amp;lt;1 m, it caused substantial damage to numerous dwellings and other structures, primarily as a result of differential &lt;span class="searchword"&gt;displacements&lt;/span&gt; and internal Assuring. Surface cracks, scarps, and compression features delineating the &lt;span class="searchword"&gt;Villa&lt;/span&gt; &lt;span class="searchword"&gt;Del&lt;/span&gt; &lt;span class="searchword"&gt;Monte&lt;/span&gt; &lt;span class="searchword"&gt;landslide&lt;/span&gt; were discontinuous, probably because &lt;span class="searchword"&gt;coseismic&lt;/span&gt; &lt;span class="searchword"&gt;displacements&lt;/span&gt; were &lt;span class="searchword"&gt;small&lt;/span&gt;; such discontinuous features were also characteristic of the other &lt;span class="searchword"&gt;large&lt;/span&gt;, &lt;span class="searchword"&gt;coseismic&lt;/span&gt; &lt;span class="searchword"&gt;landslides&lt;/span&gt; in the area, which also moved only short distances during the &lt;span class="searchword"&gt;earthquake&lt;/span&gt;. Because features marking &lt;span class="searchword"&gt;landslide&lt;/span&gt; boundaries were discontinuous and because other types of coseismic ground cracks were widespread in the area, identification of the landslides required detailed mapping and analysis. Recognition that landslides such as that at Villa Del Monte may occur near earthquake-generating fault ruptures should aid in future hazard evaluations of areas along active faults.&lt;/span&gt; &lt;/p&gt;</dc:description>
