Does it also mean that the reoccurrence interval for a magnitude 6 event has also changed?
New ways of looking at the historical record of earthquakes have also caused us to revise estimates of the recurrence time of moderate earthquakes, but only slightly. This change has not been enough to affect the hazard significantly. By ‘hazard’ we mean the amount of earthquake ground shaking expected during some time period with some specified probability. Estimates of this at any give location depend on possible shaking from all likely earthquakes. They also depend on many more factors including how far away the earthquake is, local soil conditions, etc.
