-- The 7.9 Scenario

Sam Penny is the author of two techno-disaster novels, Memphis 7.9 and Broken River, that detail what will happen to the central United States when the New Madrid once again fractures in a magnitude 7.9 earthquake just like it did in 1811. Instead of 5,000 at risk in the area, there are 32,000,000 at risk. The chances of this happening are estimated by the USGS as one in ten in the next 50 years.
