Florida has the Weirdest Looking Seismograph.

On this page are seismographs from several areas,  even one from Florida, which is totally different from all the others:  http://aslwww.cr.usgs.gov/Seismic_Data/heli2.shtml Are those fluctuations even earthquakes at all? Perhaps we should be watching this to see if there are changes due to displacement possibly caused by the evacuation of the natural gas and oil, and who knows, a collapse in the floor of the Gulf. Dee
