"A sudden spike of earthquakes in southern Kansas is raising eyebrows in the region, where there have been more earthquakes in the past two weeks than there were in the years between 1990 and 2013.
As of Oct. 26, there have been 52 earthquakes in Kansas since Oct. 15, most of a magnitude around 2.0 or 3.0. According to the Kansas Geological Survey, there were just 19 earthquakes in the state between 1990 and 2010. There were no recorded earthquakes in 2011 or 2012. The number of earthquakes in the state jumped from four in 2013 to 817 in 2014, according to the U.S. Geological Survey.
'In a typical year prior to 2013, we might have picked up one, two, three earthquakes,' said Rex Buchanan, interim director of the Kansas Geological Survey at the University of Kansas. 'Obviously we’ve outdone that dramatically.'"
