USGS Heliplots

I find the USGS heliplots pretty helpful to get a broad overview of global earth shifts.  Each graph depicts a whole day (24 hours).  The time is UTC  (same as Greenwich Meantime) and as you can probably see runs on a 24-hour clock.  The vertical lines depict earth tremors. When you follow the link, you'll be able to see the relationship of the earth's movements from one continent to the next.  It's pretty interesting stuff  : )

Hmmm...  Friday August 10th.  A global seismic shift happened at 19:00 and continued on into 20:00 UTC according to the activity on the heliplot for these times. I find this very interesting...
