Magnitude 3.8 earthquake in Indiana, no damage

INDIANAPOLIS | Thu Dec 30, 2010 10:17am EST

INDIANAPOLIS (Reuters) - A magnitude 3.8 earthquake occurred in central Indiana on Thursday morning and was felt in several nearby states but with no reports of damage or injuries, government officials said.

The quake occurred at 7:55 a.m. ET with an epicenter about 5 miles southeast of the town of Greentown, geophysicist Randy Baldwin at the National Earthquake Center in Golden, Colorado, said.

The Center had originally reported the quake magnitude as 4.2.

"It was widely felt throughout central Indiana and we have reports of people having felt it over into Illinois, Wisconsin, Kentucky and Ohio," he said, adding that the quake lasted several seconds. "We haven't had any reports of any damage."

Re: Magnitude 3.8 - INDIANA

Indiana earthquake 'extremely rare and unprecedented'

An Indiana earthquake Thursday, measured at a magnitude of 3.8, is the strongest ever recorded in that part of the state, which rarely sees earthquakes. No damage has been reported.

By Mark Guarino, Staff writer / December 30, 2010
Chicago

An earthquake that took place before sunrise Thursday in north central Indiana is being evaluated as rare despite many well-known fault lines in the area.

The US Geological Survey reported a 3.8-magnitude earthquake, centered just east of Kokomo, Ind., about 57 miles north of Indianapolis. The earthquake occurred about 3 miles underground and could be felt as far south as Indianapolis, as far east as Dayton, Ohio and as far northwest as Elgin, Ill., about 40 miles outside Chicago.

Calling the earthquake ?extremely rare and unprecedented,? John Steinmetz, director of the Indiana Geological Survey at Indiana University in Bloomington, said there have not been any earthquakes of similar magnitude in northern Indiana in 175 years. Mr. Steinmetz added that it demonstrates how little is known about the earth?s structure in that region of the country.

?We use earthquakes to plot the location of seismic activity and try to get a better picture of the deep earth. But because, in this part of the world, [earthquakes are] so infrequent and so rare, we have no picture,? he says.

Thursday?s earthquake has nothing to do with the nearby Wabash Valley Fault line but it may be connected to the Sharpsville Fault Line, located just north of Indianapolis.

HOOSIERS ENCOURAGED TO CHECK HOMES FOR EARTHQUAKE DAMAGE

INDIANAPOLIS - Public safety officials are encouraging Hoosiers to check for signs of damage to their homes, especially to chimneys and gas lines, from this morning's earthquake. A magnitude 3.8 earthquake occurred at 7:55 a.m. EST and was centered 5 miles southeast of Greentown in Howard County.

The Indiana Department of Homeland Security (IDHS) advises Hoosiers check their homes for any visible damage. Look for any new or widened cracks in floors, masonry or walls. Make sure utility lines and boxes have not been damaged.

"It's important that you report any damage to the proper authorities. If you notice any damage to your utility lines, especially gas lines, call your local utility company immediately and report the damage," said Indiana State Fire Marshal Jim Greeson.

The Indiana State Fire Marshal's Office is a division of IDHS.

To report any vibrations felt in your area, visit the IDHS webpage at www.in.gov/dhs and click on the "3.8M Earthquake registered in Howard County- Did you feel it?" link.

Indiana

Earthquake History

The most damaging Indiana earthquake originating within the State, occurred on September 27, 1909, near the Illinois border between Vincennes and Terre Haute. Some chimneys fell, several building walls were cracked, light connections were severed, and pictures were shaken off the walls. It was strong in Indianapolis and Oakland City. It was felt over an area of 30,000 square miles including the southwestern half of Indiana, all of Illinois and parts of Iowa, Kentucky, Missouri, Arkansas, and probably in parts of Kansas.

Another damaging earthquake originating in Indiana occurred on April 29, 1899, and rated intensity VI to VII on the Modified Mercalli Scale. It was strongest at Jeffersonville and Shelbyville; at Vincennes, chimneys were thrown down and walls cracked. It was felt over an area of 40,000 square miles.

In 1876, twin shocks fifteen minutes apart were felt over an area of 60,000 square miles. A shock in 1887 centered near Vincennes was felt over 75,000 square miles and an 1891 shock damaged property and frightened people in church at Evansville.

Indiana has also suffered from damage caused by earthquakes originating in neighboring States. The worst occurred on November 9, 1968, and centered near Dale in southern Illinois. The shock, a magnitude 5.3, was felt over 580,000 square miles and 23 States including all of Indiana.

Intensity VII was reported from Cynthiana where chimneys were cracked, twisted, and toppled; at Fort Branch where groceries fell from shelves and a loud roaring noise was heard, and at Mount Vernon, New Harmony, Petersburg, Princeton, and Stewartsville, all of which had similar effects. At Poseyville, "Fish jumped out of the rivers, ponds and lakes."

Almost exactly ten years earlier on November 7, 1958, an earthquake originating near Mt. Carmel, Illinois, caused plaster to fall at Fort Branch. Roaring and whistling noises were heard at Central City and the residents of Evansville thought there had been an explosion or plane crash. It was felt over 33,000 square miles of Illinois, Indiana, Missouri, and Kentucky.

On March 2, 1937, a shock centering near Anna, Ohio, threw objects from shelves at Fort Wayne and some plaster fell. Plaster was also cracked at Indianapolis. Six days later, another shock originating at Anna brought pictures crashing down and cracked plaster in Fort Wayne and was strongly felt at Lafayette.

The great New Madrid earthquakes of 1811 and 1812 must have strongly affected the State, particularly the southwestern part, but there is little information available from these frontier times.

Near New Harmony, Indiana ( 38.0N 87.5W )

1887 Feb 6 22:15 4.6M Intensity VI
Near Vincennes, Indiana ( 38.7N 87.5W )
This shock was strongest in southwest Indiana and southeast Illinois. Plaster was shaken from walls at Vincennes, Ind., and west of Terre Haute, at Martinsville, Ill.; a cornice reportedly fell from a building at Huntington, Ind. It was felt distinctly at Evansville, Ind., but only slightly in the outskirts of St. Louis, Mo. Also reported felt at Louisville, Ky.

1891 Jul 27 02:28 4.1M Intensity VI
Evansville, Indiana ( 37.9N 87.5W )
A strong local earthquake damaged a wall on a hotel, broke dishes, and overturned furniture at Evansville. The shock also was strong near Evansville at Mount Vernon and Newburgh, Ind., and at Hawesville, Henderson, and Owensboro, Ky.

1921 Mar 14 12:15 4.4M Intensity VI
Near Terre Haute, Indiana ( 39.5N 87.5W )
This earthquake broke windows in many buildings and sent residents rushing into the streets at Terre Haute. Small articles were overturned at Paris, Ill., about 35 km northwest of Terre Haute.

1925 Apr 27 04:05 4.8M Intensity VI
Wabash River valley, near Princeton, Indiana ( 38.2N 87.8W )
Chimneys were downed at Princeton and at Carmi, Ill., 100 km southwest; chimneys were broken at Louisville, Ky. Crowds fled from the theaters at Evansville, Ind. The felt area includes parts of Indiana, Illinois, Kentucky, Missouri, and Ohio.
