Some of the damage from those quakes in Japan and New Zealand resulted from a phenomenon called liquefaction. This is when the ground turns to jello or quicksand. Transmission towers topple, buildings sink and utility pipes break. Now, geologists in the Northwest have mapped the spots most likely to liquefy here in an earthquake.<p>This summer, the sound of hydraulic jacks reverberates through upscale neighborhoods near Tokyo Bay.

The scientists have been meeting this week to craft a proposal.&nbsp;</p><p>There&rsquo;s no way to predict earthquakes. But once a big one starts, it sends out different kinds of shock waves that move at different speeds. One type is fast-moving, but barely perceptible. These are called P-waves. They arrive before the slow traveling but damaging shock waves (called S-waves).&nbsp;&nbsp;</p><p>So, if you have precise sensors, they can detect the fast-moving waves and send out alarms.&nbsp;</p><p> Tue, 05 Apr 2011 23:08:36 +0000 Keith Seinfeld 1138 at http://www.kplu.org Scientists propose earthquake warning system
