Earthquake Hits Northern Illinois

3.8 Magnitude quake hits northern Illinois. CNN has the story.

The quake was originally reported as having a magnitude of 4.3, but the USGS later downgraded it to magnitude 3.8. It hit just before 4 a.m. CT (5 a.m. ET), with an epicenter about 3 miles underground. The USGS pinpointed the quake between the towns of Virgil and Sycamore, Illinois.

Millions of people felt the temblor, with reports coming in to the USGS from Georgia, Tennessee, Kentucky, Ohio, Indiana, Michigan, Iowa and Wisconsin, as well as Illinois. Members of the public sent more than 10,000 reports of the earthquake to the USGS within the first few hours after it struck.

It must be all that global warming. I am admittedly surprised that it was felt so far away. I should ask my friends in Chicago if they felt it.

The Illinois earthquake was mild compared to the one that leveled parts of Haiti last month, according to the USGS. The Haiti quake was about 33,000 times as powerful.

Thank you CNN, for pointing out the obvious.

Some of the strongest earthquakes ever known to hit the United States took place in the Mississippi River valley in 1811, 1812, and 1895, but Wednesday’s Illinois event was 250 miles or more to the north of those temblors, said Randy Baldwin, a geophysicist with the USGS.

“This is a different area geologically,” he said, calling Wednesday’s earthquake unrelated to the New Madrid quakes of the 19th century.
