Smoothed Seismicity Rates: Transcript

Karen Felzer USGS Smoothed seismicity Smoothed seismicity is used in many forecasts including the National Hazard Maps and UCERF2 to help constrain the offfault hazard It has been statistically demonstrated that smoothed seismicity is predictive of future earthquakes .
