2 more east coast earthquakes occurred Saturday December 10th.
One happened in Northern Virginia at a 2.2 around 10 AM
The 2nd happened in NJ which is still unofficial but it was said to potentially be a 2.2-2.4 magnitude, which shook up 3/4 of the state with reports from Atlantic City in southern NJ to Essex County in NE NJ somewhere between 10-11 am
This is on top of the one that happened back on August 23rd, with a 5.6 magnitude centered around Virginia and shaking was felt as far north as Massachusetts right before Hurricane Irene came along.
Certainly something interesting is going on with the earth and tectonic plates, 3 east coast quakes within a few months is unheard of.
