Here in the NorthEast USA the primary power failures are: Thunderstorm or snowstorm related. Usually either a power line gets knocked out or a local transformer blows out. Occasionally, we get power grid overload related problems. Usually they are localized. If you also have a land line telephone, it will usually work while the electricity is out (wireless phones and powered phones not withstanding). I have often called the "electric company" during a power outage. Cell phones are a different matter. Don't most of them have generators at the cell site to prevent the loss of communications? Its only the case where the lines went down close to you that has the best chance of knocking all of your services out. Of course, I'm sure there are location in the country where everything is "close to you", so, YMMV. > But then we haven't had a significant quake here since September 1968, > and when we did the epicentre was far from built-up areas.
