Ground quakes again in southern Nebraska

NEBRASKA -- The ground could be felt shaking again along the Nebraska-Kansas border as a second earthquake within a week's time occurred Tuesday morning. 

The 3.6 magnitude quake happened just after seven this morning. 

The U.S. Geological Survey said it was centered about six miles southwest of Superior, just across the state line in Kansas. 

This is similar to another quake that was felt a little over a week ago as far north as York. 

No word yet on how far this recent quake was felt.
