For the first time we'll actually see how the fault moves in real time.

A big earthquake in the same region as the 1811-1812 earthquakes would have devastating consequences should they recur today because of the population centers around St. Louis and Memphis.

This is not an earthquake prediction instrument. We are testing whether these types of earthquakes on this particular fault are predictable.

The project is going to have a profound influence. We are opening a door to new areas of research that will pay off over time. We'll be learning things for months and years to come.
