An earthquake is the sudden release of energy from the Earth’s crust which results in seismic waves that can be destructive. Most earthquakes are associated with particularly active regions of the Earth where huge plates contact each other. Hennepin County is far from these active regions and is in a relatively stable area of middle North America. However, earthquakes have struck Minnesota and will almost certainly continue to do so in the future. The closest earthquake epicenters to Hennepin County were in Cottage Grove in 1981 (measured 3.6 Richter scale) and in New Prague in 1860 (estimated 4.7 Richter scale). Hennepin County has a much lower risk of earthquakes than most of the rest of the United States.
