The north American plate is 2/3 land mass covering both the United States and Canada. There are many good locations in both places due to what is called the Canadian shield. It is constructed of very old and stable rock with very little earthquake activity and no known volcanic activity. The west coast from central America up along the coast to Alaska, is a divergent (spreading) boundary. The bottom part of Alaska is a subduction zone where the Pacific plate will submerge under Alaska along the Alaskan chain causing volcanoes and earthquakes in these areas. There is no known volcanic activity north of these areas, some activity to the west in the mountains and to the south increasing into central America. These areas will probably be heavily populated.
Good locations would include Alberta, Saskatchewan, Manitoba, and Ontario. The elevations of these areas range from 650 feet in Ontario and Manitoba to 3000 feet in areas of Alberta. One must keep in mind when choosing a location to stay 100 miles from major bodies of water such as Hudson Bay and The Great Lakes because of inland tidal waves and avoid being high in the mountains to the west due to earthquake activities that will occur there.
The United States
Good locations would include the eastern half of Montana, North Dakota, South Dakota, Nebraska and the north east corner of Wyoming. The elevations in these areas range from 650 feet in North and South Dakota and Nebraska and up to 3000 feet or more in areas of Montana. Parts of Minnesota may be OK in the western half of the state but remember to stay at least 100 miles from Lake Superior. These areas have a little more earthquake activity than Canada, decreasing in activity the farther north you go towards the Canadian border.
Iowa has an elevation is 650 feet to 1500 feet but there may be little protection from the winds. I would not call Wisconsin a real good place because of the Great lakes being so close and you will probably get little protection from the winds here. I would not call Illinois a good place to be either as it is also too close to the Great Lakes. The southern half may be OK from tidal waves, but will probably have little protection from the winds. Also, the elevation of Illinois is 650 feet or less from what I can tell. Not good for any kind of stability after the pole shift due to high waters moving inland.
