Indiana earthquake 2010 Video is the most scene waited by the people in Indiana as of now the people try to get the information about the Indiana Earthquake Stream

A 3.8 magnitude earthquake rattled portions of Central Indiana Thursday morning--and was even felt by some Chicago residents.

Indiana experienced a rare Midwestern phenomenon this morning, when a magnitude 3.8 earthquake shook even people in border states Illinois, Wisconsin, Kentucky and Ohio.

The earthquake occurred just before 8 a.m. just outside Greentown, Ind. It lasted just a few seconds and no one was injured. One man told the local paper than his dog even slept through it. It was enough to get people talking though, mostly saying, "Hey, did you feel that?"

Scientists say that quakes under magnitude 5.0 have a shaking radius (definitely not the official term) of about 100 miles.

While Midwestern earthquakes are rare, this was a good reminder that experts still believe that the New Madrid Seismic Zone underneath Missouri is active.

According to Reuters, quakes there in 1811 were felt over 50,000 square miles. So hold on, Missourians!

The U.S. Geological Survey initially estimated the quake's strength was magnitude 4.2, but since lowered that number, according to the Associated Press.

Residents of Chicago, Naperville and Buffalo Grove, Illinois told NBC Chicago they felt their beds shaking and saw their ceiling fans move early Thursday. A geophysicist told the AP a 3.8 magnitude quake "would feel like a loaded truck passing by."

The Indiana Geological Survey had no records of a 3.8 magnitude earthquake in Central Indiana ever, according to the Indianapolis Star. The director of the IGS told the Star that the quakes location--about 3 miles below the ground--was "highly irregular" and "extremely rare."

Indiana's last major earthquake was on April 18, 2008. The 5.2 magnitude quake was the strongest to hit the state in 40 years, the Star reports.

No injuries or damage had been reported as of 9:30 a.m. CT.

According to the USGS, the earthquake’s epicenter was located about 50 miles north of Indianapolis. The quake began at 7:55 a.m. and was located approximately three miles beneath the surface. The Indiana earthquake lasted just a few seconds, but the 3.8 magnitude trembler was powerful enough to be felt in Illinois, Ohio, Kentucky and Wisconsin.

Initially, the Indiana earthquake was reported as a 4.2 magnitude earthquake, but the USGS downgraded the earthquake to a 3.8. The booms that accompanied the earthquake in Indiana, while frightening, were not out of the ordinary for an earthquake, said USGS geophysicist Randy Baldwin, but that didn’t stop people from bombarding law enforcement with calls.
No fault lines in the area

Michael Hamburger, a geologist at Indiana University, told local television station WTHR that the Indiana earthquake occurred in an area that is not common for earthquakes, an area that is “seismically very quiet.” Considering that there are no fault lines nearby, it seems odd that there could be much Indiana earthquake history.

Yet as Baldwin put it, wherever stress builds up in the earth’s crust, an earthquake can follow.
A brief Indiana earthquake history

Among the earliest recorded incidents in Indiana earthquake history was the 1811 and 1812 New Madrid earthquakes. This massive series of earthquakes is estimated at anywhere from 7.0 to 7.7 on the Richter scale. The most damaging Indiana earthquake on record was noted on Sept. 27, 1909, near the Illinois border between Vincennes and Terre Haute. While only a 5.1 magnitude quake, its extended nature caused a great deal of structural damage to homes and other buildings. The 1909 quake was felt over 30,000 square miles.
