WebAug 6, 2024 · A time interval during which all possible earthquakes may occur is set in order to determine the shaking hazard. The time interval is typically set to 50 years. The 50-year period can be ANY 50 years, not just the NEXT 50 years; the red bar above can span any 50-year period. (Public domain.) Sources/Usage: Public Domain. WebJan 1, 2016 · Frequency. The frequency of a natural hazard event is the number of times it occurs within a specified time interval. Magnitude. The magnitude of a natural hazard event is related to the energy released by the event. It is distinguished from intensity which is related to the effects at a specific location or area.
