The fans of the New England Patriots celebrating their team’s hosting of the AFC Championship Game this weekend weren’t the only thing causing the ground to shake in New England.

The U.S. Geological Survey reports that a series of five earthquakes rocked eastern Connecticut area on Monday.  The strongest quake, magnitude 3.1, was felt in parts of Rhode Island and Massachusetts.

The USGS says that four of the quakes struck in a 20 minute span starting around 6:30 a.m. Eastern Time.

John Ebel, senior research scientists at the Western Observatory told WCVB-TV the quakes are not as unusual as you would think for that area.  He stated there is a tectonic plate from the West Coast to the middle of the Atlantic Ocean.

He said the quakes are caused by pressure being rleleased from those two boundaries.
