Is the USGS site corrupt and being tampered with to make it look like not so many earthquakes are happening?
Is it a case of this site not being very accurate?
Or is it just a simple matter of this site not being able to document every single earthquake that happens in the world?
This site has graphs which claim to display the total amount of earthquakes happening in the world each year.
Given the discrepancies, their earthquake stats can't be very accurate and they shouldn't display annual graphs that are an understatement of the actual earthquakes happening across the world when there is in fact a lot more occurring.
Has anyone else noticed discrepancies with this particular site?

I heard people in Yellowstone are feeling quakes and that USGS isn't reporting them.
I think they are trying to make it all seem "less awful" than it actually is. Leave it to the government.

I am pretty sure that the site in question only lists world wide quakes above a certain magnitude, ???.....but it lists all the U.S. quakes (it says that somewhere on the site too)
there was a thread about this recently, they said this is being done to manipulate data to show that there are less earthquakes than there really are.
I think they should show them all, but what do I know
"Maps show events recorded in the last 7 days with M2.5+ within the United States and adjacent areas, M4.5+ in the rest of the world."edit on 3-3-2011 by BadBoYeed because: (no reason given)
