Why the Eastern US has Fewer Earthquakes than the Western US [1]

Accuweather - Vickie Frantz, 10/22/12

When you hear about an earthquake in Maine, you are more shocked than when you hear about an earthquake in San Francisco. There is no doubt that earthquakes in the western U.S. are more frequent than those to the east of the Rocky Mountains, according to the United States Geological Survey (USGS).

Just how more frequent are earthquakes in California than in Maine? For the years of 2010 through present, 13 earthquakes of a magnitude of 2.0 or greater were reported in Maine. In the state of California, 57 earthquakes of a magnitude 2.0 or greater were reported during the week of Oct. 13, 2012 through Oct. 20, 2012.
