http://neic.usgs.gov/neis/bulletin/ I know very little of geological science. The question is should we have some concern over the # and scale of these quakes. Is this unusual or is it simply the day to day rumblings of our planet? Quite frankly, seeing all of these with 4,5, and 6 next to them is a bit unsettling but I'm not very knowledgable of the science behind it. Seems that the Sci/Tech forum was a good place to throw it out for feedback.
