Emergency responders from Illinois, Indiana and other nearby states are spending this week preparing for the possibility of an earthquake.
A major earthquake along the New Madrid or Wabash Valley seismic zones could prove to be catastrophic.
Officials say that it is important to be prepared for what is an unpredictable event.
One of the biggest dangers of an earthquake is falling debris and objects inside a building.
