See Ruth's books. Note that there are no absolutely safe areas. But it would still be subject to high winds on the order of 180 MPH which would flatten just about everything. In a basement shelter, you'd be safe during the shift. Even inland, the wind can blow debris fast enough to cause devastation.
Oil needs to be imported by ship or pumped through pipelines.
Few ships will be left after the shift, and pipelines are very vulnerable. I was surprised to find that coal-burning power plants are built at the mine sites. Fuel delivery should be no problem. Look for plants in hilly or mountainous terrain. See other EPA MAPS .
