WBEZ | Seth Stein http://www.wbez.org/tags/seth-stein Latest from WBEZ Chicago Public Radio en Indiana earthquake felt in five states http://www.wbez.org/story/indiana-earthquake/indiana-earthquake-felt-five-states <p><p><span style="font-size: 10pt;">No damage or injuries have been reported from an earthquake that hit north of Indianapolis this morning. </span></p><p><span style="font-size: 10pt;">According to the U.S Geological Survey, the 3.8 magnitude quake was felt in parts of Indiana, Michigan, Ohio, Kentucky, Wisconsin and Illinois. Seth Stein is a professor of Earth Science at Northwestern University. He said the far reach of today's quake is typical for this region. </span></p> <div><span style="font-size: 10pt;">&ldquo;In the Midwest the rocks are old and cold,&rdquo; Stein said. &ldquo;And they transmit seismic energy pretty well, as opposed to the warmer softer rock of the west.&rdquo;</span></div> <div>&nbsp;</div> <div><span style="font-size: 10pt;">Stein said earthquakes of this magnitude occur fairly often throughout Indiana and Southern Illinois, though he said today's quake hit along a fault that's farther north of the Wabash Valley fault where most of Indiana's seismic activity occurs. </span></div></p> Thu, 30 Dec 2010 18:05:00 -0600 http://www.wbez.org/story/indiana-earthquake/indiana-earthquake-felt-five-states December 16, 1811: A series of disastrous earthquakes shake Midwest http://www.wbez.org/blog/clever-apes/december-16-1811-series-disastrous-earthquakes-shake-midwest <img typeof="foaf:Image" src="http://llnw.wbez.org/scientist2.jpg" alt="" /><p><p class="MsoNormal">Clever Apes meets a lot of creative and productive scientists.&nbsp; Turns out some of them also write books, and ones you might want to pick up. Today we&rsquo;re beginning an occasional series&mdash;let&rsquo;s call it Wordy Apes&mdash;sort of a book-club-on-the-blog.</p> <p>And the subject today: earthquakes.&nbsp; In particular, the New Madrid earthquake zone that stretches from southeastern Missouri, and includes parts of Arkansas, Tennessee, Kentucky, Indiana and on up to southern Illinois.</p> <p>Seth Stein is fascinated with New Madrid.&nbsp; By day Stein&rsquo;s a professor of geological sciences at <a href="http://www.earth.northwestern.edu/current/people/faculty/seth/">Northwestern University</a>.&nbsp; He&rsquo;s been tracking seismic change along the New Madrid zone for decades, including applying space-age GPS technology to measure movement in the area. What he and his colleagues have found: the movement they expected just isn&rsquo;t happening.&nbsp; <a href="http://cup.columbia.edu/book/978-0-231-15138-2/disaster-deferred">His book,</a> <em>Disaster Deferred: How Science is Changing Our View of Earthquake Hazards in the Midwest</em>, documents their work, and what it means for understanding what Stein calls the &ldquo;mysterious zone.&rdquo;&nbsp; There are all kinds of implications here, from how disaster preparedness money is used to why many people expect&mdash;wrongly, in Stein&rsquo;s view-- new Midwest earthquake disasters.&nbsp;Today&rsquo;s date figures in.&nbsp; On December 16, 1811, the first of a series of earthquakes along the New Madrid zone shook the Midwest.&nbsp; Listen to the interview above, as Seth Stein describes those events, and the scientific inquiry that it&rsquo;s ignited.&nbsp;</p><p>And, below, Professor Stein offers his down-to-earth explanation of friction, resistance and earthquake occurence.&nbsp; &nbsp; <font face="Times New Roman" size="3"><span style="font-size: 12pt;"><br /></span></font></p> <p class="MsoNormal">&nbsp;</p> <p><iframe width="485" height="364" frameborder="0" src="http://player.vimeo.com/video/17375116?title=0&amp;byline=0&amp;portrait=0&amp;color=ab050d"></iframe></p></p> Thu, 16 Dec 2010 08:02:00 -0600 http://www.wbez.org/blog/clever-apes/december-16-1811-series-disastrous-earthquakes-shake-midwest
