IU scientists detect seismic signals produced by tornado activity http://apocadocs.com/s.pl?1331228420
An Indiana University geophysical experiment detected unusual seismic signals associated with tornadoes that struck regions across the Midwest last week -- information that may have value for meteorologists studying the atmospheric activity that precedes tornado disasters.
The experiment by IU researchers involves deployment of more than 100 state-of-the-art digital seismographs in a broad swath of the U.S. midcontinent. One of the twisters that struck southeastern Missouri and southern Illinois on Feb. 29 passed through the seismic detection array.
