What is the only U.S. state that has never had a earthquake?
According to the U.S. Geological Survey's Earthquake Information Center, every state in the U.S. has experienced an earthquake of one kind or another.
The last notable seismic activity to occur in Florida happened in 2006; the time before that was in 1952. And North Dakota, which was last shaken by a quake centered in Minnesota in 1975, has only had a handful of incidents as well. The last shock that was centered in that state happened in Huff, N.D. in 1968 and had a magnitude of 4.4.
If you are trying to get away from earthquakes, you may want to move to Antarctica. According to the USGS it has fewer earthquakes than any other continent.
