Tectonic Summary
Earthquakes in the Stable Continental Region
Most of North America east of the Rocky Mountains has infrequent earthquakes. Here and there earthquakes are more numerous, for example in the New Madrid seismic zone centered on southeastern Missouri, in the Charlevoix-Kamouraska seismic zone of eastern Quebec, in New England, in the New York - Philadelphia - Wilmington urban corridor, and elsewhere. However, most of the enormous region from the Rockies to the Atlantic can go years without an earthquake large enough to be felt, and several U.S. states have never reported a damaging earthquake. The earthquakes that do occur strike anywhere at irregular intervals.Earthquakes east of the Rocky Mountains, although less frequent than in the West, are typically felt over a much broader region. East of the Rockies, an earthquake can be felt over an area as much as ten times larger than a similar magnitude earthquake on the west coast. A magnitude 4.0 eastern U.S. earthquake typically can be felt at many places as far as 100 km (60 mi) from where it occurred, and it infrequently causes damage near its source. A magnitude 5.5 eastern U.S. earthquake usually can be felt as far as 500 km (300 mi) from where it occurred, and sometimes causes damage as far away as 40 km (25 mi).
Faults
Earthquakes everywhere occur on faults within bedrock, usually miles deep. Most of the region's bedrock was formed as several generations of mountains rose and were eroded down again over the last billion or so years.At well-studied plate boundaries like the San Andreas fault system in California, often scientists can determine the name of the specific fault that is responsible for an earthquake. In contrast, east of the Rocky Mountains this is rarely the case. All parts of this vast region are far from the nearest plate boundaries, which, for the U.S., are to the east in the center of the Atlantic Ocean, to the south in the Caribbean Sea, and to the west in California and offshore from Washington and Oregon. The region is laced with known faults but numerous smaller or deeply buried faults remain undetected. Even most of the known faults are poorly located at earthquake depths. Accordingly, few earthquakes east of the Rockies can be linked to named faults. It is difficult to determine if a known fault is still active and could slip and cause an earthquake. In most areas east of the Rockies, the best guide to earthquake hazards is the earthquakes themselves.

Confusion in Corbin over fake "quake"
CORBIN, Ky. (WKYT) - It's been described as an explosion,
an earthquake, a thunder roll, or even as small as a car crash. Some say
there was one tremor, others say two, one resident said they felt three
violent shakes, and yet some say they didn't feel anything at all.
While the reports vary, the reality is something rattled Corbin around midday on Wednesday."Just a couple of seconds, it didn't last long," described Christopher Day, "I thought it was thunder and I looked up in the sky and, of course, it was sunny and cold out. It couldn't be thunder."
But Day wasn't the only one to feel it, Deanna Rains said dishes began falling into her sink.
"I actually had my coffee pot break from my refrigerator," said Rains, "I was thinking oh my god, is my trailer going to fall apart? Or is the ground going to split open or something? I mean it was horrible!"
The Whitley County 911 Call Center made a map estimating the locations of callers to 911 centers in their county as well as in Laurel, Knox and McCreary counties. The tremors were that widespread.
"We've yet to determine what this was. It sounded like a minor earthquake, but we can't get it verified," answered Sheriff Colan Harrell.
So, was it an earthquake? If anyone would know it'd be the UK Geological Survey.
"I took a look through our records and so far I haven't seen anything that does not look uncharacteristic. There's a of activity but that's normal," explained Seth Carpenter, adding he believes it was likely a mine blast on the surface level, and did not register on their seismology readouts.
So was it an explosion?
I called several mining companies to see if they were blasting in the area that could explain the shaking. They all denied it, saying their blasts are typically smaller and kept to a mile-wide radius.
Danny Moses, the Whitley County Emergency Management Director, said he began trying to solve the mystery as soon as it happened. He checked every possible blasting site, and said he still had not found the answer.
So the mystery continues.
"There could also be something else going on," estimated Carpenter.
"I still have no idea. It was definitely something," stated Day.
Moses said he has not found any major damage to the area. Still, those who felt the tremors want answers, but for now they'll have to wait.

Update About the Louisiana Sinkhole: The worksite is cracking apart and the sinkhole expands
on: January 20, 2013, 14:54The worksite started to crack apart on the 19th of January 2013. The working crews were evacuated. Methane gas and the whole area may explose since it is full of methane gases.

State and Parish leaders are on alert in Assumption Parish after the sinkhole "burped" again today. It happened at 10am and caused heightened anxiety in an already tense area.
Parish officials said hydrocarbons and debris bubbled up to the surface and caused major cracks in a well pad. All activity at that well pad had to be shut down.
PHOTO COURTESY: Dean Wilson.
"There is additional cracking that has occurred on well pad three," John Boudreaux, Assumption OEP Director said. "They are an inch wide and a ruler goes down 14 inches. It seems that land is sloughing in toward the sinkhole."
Officials will continue monitoring the situation. State Police sent their helicopter in the air to monitor the sinkhole from above.
