Which major US cities are located in earthquake zones?
Anchorage, Los Angeles, San Francisco, Seattle, San Diego, Salt Lake City, St. Louis, Memphis, Louisville, Charlestown, DC, New York, NY, Boston, Las Vegas, Portland, Little Rock, and Reno, NV are all high on the earthquake hit list.
A large number of cities are built in earthquake zones on or near fault lines. Earthquakes can create nice deep harbours, hills with nice views and other topography to make a good place to build a city (San Francisco is good example). There are far too many cities to list here but many of the cities that have coastline on the Pacific ocean have fault lines nearby....
California is in the "Pacific" time zone. Mexico spans three time zones, Pacific, Mountain and Central. Therefore, depending on where in Mexico you start your journey to California, the answer is either 0, 1, or 2. As most of the major cities, including Mexico City, are located in the Central time zone, the most common answer would be 2.
