Most people, including those who live there, regard Kansas as a seismically quiet place. Until a couple of years ago, hardly anyone I met from Kansas had felt an earthquake that had originated within the state. That all changed about 18 months ago. In the fall of 2013, the state experienced several events, reported by the U. S. Geological Survey (USGS) and Oklahoma Geological Survey (OGS), including a magnitude 4.2 earthquake in December 2013. In 2014, the USGS National Earthquake Information Center reported more than 100 events with epicenters inside Kansas. The largest was a magnitude 4.9 in November 2014.
