WebThis motion can be used to infer the strain rate in the crust. In the case of the New Madrid Seismic Zone, the faults are buried, so GPS data can help to find out exactly where the faults are and to determine the direction and extent of motion along them.

WebRecurrence-interval terminology tends to be more understandable for flood intensity comparisons. It’s easier to understand that a 100-year flood is greater than a 25-year flood. In recent years the USGS and other agencies are more often referring to the percent chance of occurrence of a flood in terms of its Annual Exceedance Probability or ...
