Did I just feel an earthquake?

And this is the 1895 quake that was not as strong as the three quakes of December 1811, January 1812 and February 1812.

Well that is pretty scary then. I wonder what the map would look like from the 1812 one.

Wow I can't click on page four of this thread due to it having a paper clip and green circle icon on it. So I had to click on page 3 and then hit last. Only time that's ever happened.

Oklahoma Earthquake Linked to Fracking?
by Timothy Hurst on November 6, 2011

Was the earthquake the United States Geological Survey is now calling the largest earthquake on record in Oklahoma linked to hydraulic fracturing, or fracking, the widely used but contentious oil and gas production technique which vastly increases the quantity of fossil fuels retrievable in a well?

As of Sunday night, 23 earthquakes have been recorded in central Oklahoma in the last 24 hours. The biggest quake in the latest seismic flurry, the 5.6-magnitude earthquake centered near Sparks, Oklahoma on Saturday night, could be felt as far north as Illinois and Wisconsin.
