1. The Danger of a Major Earthquake

The U.S. Geological Survey has created maps that show areas of probable earthquakes for the entire United States (2002 National Seismic Hazard Maps).

While a large earthquake that will seriously affect southwestern Indiana is inevitable, it is currently impossible to predict when the next “big one” will occur, or even whether it will happen during our lifetimes. While fearing the inevitable is pointless, it would be prudent for government officials and citizens to begin taking basic steps to prepare for
a major quake.

A recent press release of the U.S. Geological Survey stated that there is a 25 to 40 percent chance of a magnitude 6.0 or greater earthquake in the next 50 years for the central United States. There is a 7 to 10 percent chance of a repeat of events similar to the 1811-12 earthquake.
