A rare 4.0 magnitude earthquake rattled New England, last night. While some of our readers on the West Coast would barely even blink with such a shake, it caused confusion and consternation for many around the epicenter about 30 miles outside of Portland, Maine.

The Bangor Daily News reports that the largest earthquake to strike the region measured 5.1 and it happened in 1904.

An earthquake has struck southern Maine and rattled nearby New England states.

The U.S. Geological Survey  said the epicenter of the quake was about 3 miles west of Hollis Center, Maine, and about 3 miles deep. That location is about 20 miles west of Portland.

The quake was felt in Vermont, New Hampshire and Massachusetts, including Boston, and as far south as Rhode Island and Connecticut.

Quakes Caused By Waste From Gas Wells, Study Finds

The U.S. Geological Survey will soon confirm that the oil and gas industry is creating earthquakes, and new data from the Midwest finds that these man-made quakes are happening more often than originally thought.

Earthquakes happen when faults in the Earth slip and slide against each other. There's continuous stress on innumerable faults on our continent, but seismologists like Bill Ellsworth, from the U.S. Geological Survey, started seeing something odd about 12 years ago.

A Fracking Disaster?

The magnitude 5.8 earthquake that rattled the east coast back in August triggered speculation about whether the controversial gas drilling technique called fracking may have been responsible. Fracking involves drilling thousands of feet into the shale deep below the earth’s surface, then fracturing the earth by pumping millions of gallons of sand, water, and chemicals into the shale to release natural gas. So far, contamination of groundwater supplies has been the focus of those opposing big energy’s push to expand fracking.

The growing evidence for a connection between the controversial drilling technique called"fracking" and earthquakes. A shocking tactic used by a Connecticut high school to clear the hallways for a drug search. And a new documentary follows a group of friends on their journey from impulsive teenagers to soldiers in Afghanistan, and then back again.
