Earthquakes, there's an App for that

If you're not sure whether you felt the Earth move Tuesday, there's an app for that.

A number of free and paid applications that help users track seismic activity are available for Apple and Android platforms.

Earthquake Lite, a free application available through Apple's iStore delivers live earthquake date to your phone using data from numerous services including the U.S. Geological Survey, GeoNet and the British Geological Survey among others.

Residents within a nine-state area of a southeastern Missouri earthquake could get good use out of such an application after a Tuesday morning earthquake.

The U.S. Geological Survey says the magnitude 4.0 earthquake was centered near the town of East Prairie, Mo. Geological Survey geophysicist Amy Vaughan says several people in Missouri, Arkansas, Illinois, Kentucky and Tennessee reported being awakened by the quake that happened at 3:58 a.m. A few residents of North Carolina, Alabama, Indiana and Georgia also felt it.

East Prairie City Administrator Lonnie Thurmond says the shaking lasted about seven seconds. Vaughan says he's heard reports of cracks in sidewalks and walls, some broken windows, and minorhousehold damage such as rattled shelves and things falling from cabinets.
