Tiny Tremors Can Track Extreme Storms In A Warming Planet Santa Fe NM (SPX) Apr 21, 2008 Data from faint earth tremors caused by wind-driven ocean waves-often dismissed as "background noise" at seismographic stations around the world-suggest extreme ocean storms have become more frequent over the past three decades, according to research presented at the annual meeting of the Seismological Society of America. |
