  <dc:description>&lt;p&gt;&lt;span&gt;The multichannel analysis of surface waves (MASW) seismic method was used to delineate a fault zone and gently dipping sedimentary bedrock at a site overlain by several meters of regolith. Seismic data were collected rapidly and inexpensively using a towed 30-channel land streamer and a rubberband-accelerated weight-drop seismic source. Data processed using the MASW method imaged the subsurface to a depth of about&amp;nbsp;&lt;/span&gt;&lt;span class="equationTd inline-formula"&gt;&lt;span id="MathJax-Element-1-Frame" class="MathJax" data-mathml="&lt;math xmlns=&amp;quot;http://www.w3.org/1998/Math/MathML&amp;quot; display=&amp;quot;inline&amp;quot; overflow=&amp;quot;scroll&amp;quot;&gt;&lt;mrow&gt;&lt;mn&gt;20&lt;/mn&gt;&lt;mspace width=&amp;quot;0.3em&amp;quot; /&gt;&lt;mi mathvariant=&amp;quot;normal&amp;quot;&gt;m&lt;/mi&gt;&lt;/mrow&gt;&lt;/math&gt;"&gt;&lt;span id="MathJax-Span-1" class="math"&gt;&lt;span&gt;&lt;span id="MathJax-Span-2" class="mrow"&gt;&lt;span id="MathJax-Span-3" class="mrow"&gt;&lt;span id="MathJax-Span-4" class="mn"&gt;20&lt;/span&gt;&lt;span id="MathJax-Span-5" class="mspace"&gt;&lt;/span&gt;&lt;span id="MathJax-Span-6" class="mi"&gt;m&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span class="MJX_Assistive_MathML"&gt;20m&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span&gt;&amp;nbsp;and allowed detection of the overburden, gross bedding features, and fault zone.

Mapping of shallow-fault zones and dipping sedimentary rock substantially extends the applications of the MASW method.&lt;/span&gt;&lt;/p&gt;</dc:description>
