The Rio Grande rift has a relatively short and unimpressive record of historical seismicity. However there is abundance evidence of prehistoric (Quaternary) surface faulting associated with large (M>6) earthquakes. This paradox between historical and prehistoric seismicity (paleoseismicity) has important implications for seismic-hazards analyses based primarily on modern seismicity.
