Even those areas without a history of earthquakes or rare instances of measurable earthquakes may have quakes in the future. Although a lot has changed topographically and architecturally since the New Madrid quake(s) of the early 1800s, those quakes were felt and caused damage to a varying degree here in Washington, DC. Given some areas still have few structures and other surface features that would stand up to a moderate earthquake (although it is my understanding that some nuclear plants and protective features around the country have been built to withstand up to a 8+ earthquake).
We (in the emergency management community) are learning about new tectonic issues in our areas of responsibility every day. Although, to be perfectly honest, my present position is less involved than some of you.
FWIW: I studied >>> a little <<< plate tectonics and geology in the 1970s and 80s Marine Science Technician (in the classroom and as a technician for NSF and Contract scientists on an icebreaker in the Arctic and Antarctic) in the Coast Guard.
Be safe out there and Happy Fathers Day to you and your loved ones!

Subject: [californiadisasters] Re: New hidden earthquake fault found in California
Thanks for your responses to my remarks. I know Louisiana has an earthquake history although not very much of one. What made me think to comment about this was the remarks about the dam and the earthquake fault earlier. Structures like dams, levees, etc. are really only useful as long as the ground around them does not move!
As for fearing hurricanes ... I think in many ways an earthquake is worth because to my knowledge there is no dependable way of forecasting them. You can watch a hurricane coming all the way from Africa if you know where to go to see the images, and of course listen to the forecasters. But I've never heard of earthquake watches or warnings. Maybe someday .... but not yet to my knowledge.
