Nvizabillat's Feb. 2012 EQ Report For Central US

Posted by Sista SoulJah on March 19, 2012 at 9:55 AM

These are the thirty six recorded earthquakes that occurred in the month of February 2012 in the Central region of the United States. As I pointed out previously the month started out slow with earthquakes occurring at the rate of < 0.50 earthquakes per day (EQPD) during the first half of the month. Then things started picking up a bit beginning February 21st with a 4.3 magnitude earthquake that struck the New Madrid region, (Only later to be downgraded to a 3.9, This quake still shows at 4.5 at the GFZ German Research Centre for Geosciences website), this quake was felt in twenty states ! Seventeen more earthquakes would occur after that to bring us to our monthly total.

Also, some time after that February 21st trembler, I noticed that five more earthquakes were added to the report that wasn't listed previously, I denoted these earthquakes with an asterisk (*) on the report. I find it rather odd that these were only added after the 4.3 occurred, they were in the same area, and the helicorders that I reviewed for the two on the 20th, at the times listed, showed no seismic activity whatsoever. This kind of thing is something that I'm really going to have to keep a closer eye on.
