A few facts about Earthquakes to start off your week.

  • The largest recorded earthquake in the United States was a magnitude 9.2 that struck Prince William Sound, Alaska on Good Friday, March 28, 1964 UTC.
  • The largest recorded earthquake in the world was a magnitude 9.5 (Mw) in Chile on May 22, 1960.
  • The Wasatch Range, with its outstanding ski areas, runs North-South through Utah, and like all mountain ranges it was produced by a series of earthquakes. The 386 km (240-mile)-long Wasatch Fault is made up of several segments, each capable of producing up to a M7.5 earthquake. During the past 6000 years, there has been a M6.5+ about once every 350 years, and it has been 150 years since the last powerful earthquake.
  • From 1975-1995 there were only four states that did not have any earthquakes. They were: Florida, Iowa, North Dakota, and Wisconsin.
  • Florida and North Dakota have the smallest number of earthquakes in the United States.
  • Alaska is the most earthquake-prone state and one of the most seismically active regions in the world. Alaska experiences a magnitude 7 earthquake almost every year, and a magnitude 8 or greater earthquake on average every 14 years.
