In 2005, they recorded thousands of small quakes within a couple of weeks along the Juan de Fuca Ridge northwest of Astoria. Those earthquakes were smaller, he pointed out, and located along the tectonic plate boundary.</font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; line-height: 15px; "><font class="Apple-style-span" face="Arial" size="3"><span class="Apple-style-span" style="font-size: 13px; line-height: normal;"><br></span></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; line-height: 15px; "><font face="Arial" size="4" style="font: 13.0px Arial">This is the eighth such swarm over the past dozen years, Dziak said, and the first seven were likely because of volcanic activity on the Juan de Fuca ridge. The plate doesn't move in a continuous manner and some parts move faster than others. Movement generally occurs when magma is injected into the ocean crust and pushes the plates apart. - <span class="Apple-style-span" style="font-family: Verdana; font-size: 14px; "><a href="http://www.sciencedaily.com/releases/2008/04/080413184801.htm">Science Daily</a></span></font></div></span></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; line-height: 18px; "><font class="Apple-style-span" face="Verdana" size="4"><span class="Apple-style-span" style="font-size: 14px; font-weight: normal; line-height: normal;"><br></span></font></div></b></span></font></div></div><div><div><html>On Apr 15, 2008, at 11:26 PM, Hal Snyder wrote:</html><br class="Apple-interchange-newline"><blockquote type="cite">I just started looking into fresh water issues.
