   We use a series of sideview panels created by Dr. Raymond Anderson of the Iowa Geological Survey Bureau (and used here with his permission) to show the steps in developing the Manson structure. The writer, during the 1960s, when he was working primarily on impact structures, is generally credited with "proving" the impact origin of this very large crater, which, at one time, many thought was the "smoking gun" that killed the dinosaurs, until we found its age and disqualified it.

   "An earthquake of that magnitude would do so much damage down in that area - it would devastate St. Louis and Memphis and screw up the infrastructure so bad that damage in Iowa wouldn't even get noticed," said Raymond Anderson, a supervisor with the Iowa Geological Survey Bureau.
   
   An additional dozen Iowa locations have been the epicenter (origination point) of earthquakes since 1867, the most recent in 1948. All were so minor that they were not recorded by scientific instruments, only by people reporting that the ground shook. The information was gathered from newspaper accounts of the time and it has been verified by modern-day research.
   
   The epicenter is "the surfaced expression of where the earthquake is. In other words, you're standing right above it," Anderson said.
   
   The New Madrid Zone was the site of the worst incident in U.S. history: three earthquakes that occurred in 1811 and 1812, measuring between 8.3 and 8.7 in magnitude.
   
   Stories still abound about that, Anderson said.
   ...
   When it does, that shock wave of the slippage is what causes the earthquake," Anderson said.
   
   Iowa is located in what geologists call the "stable midcontinent" area, so named because the ground is stable, with few earthquakes.
   
   "The rocks that are here are old, they're thick, they're cold," Anderson said.
   ...
   "There wasn't a credible geologist or geoscientist that agreed with him," and not a thing happened that day, Anderson said.
   
   Anderson said the odds are against another huge earthquake at the New Madrid Zone for hundreds of years. He went on to explain why.
