WebJul 31, 2024 · The Recurrence Interval also known as a return period or repeat interval, is an average time or an estimated average time between events such as earthquakes, … A return period, also known as a recurrence interval or repeat interval, is an average time or an estimated average time between events such as earthquakes, floods, landslides, or river discharge flows to occur. It is a statistical measurement typically based on historic data over an extended period, and is used usually for risk analysis. Examples include deciding whether a project should be allowed t…

In order to assess seismic risk, we want to know how often a large earthquake happens in this region. How do we do that if our seismometers haven’t …
When geologic events are random or quasi-random, it is helpful to represent their frequency as an average time between past events, a "recurrence interval" also known as a "return time." For instance, there have been 7 subduction zone earthquakes in the Pacific Northwest in the past 3500 years, giving a … See more Generally, there are four concepts that our students struggle with when studying recurrence intervals: 1. the concept of a recurrence interval 2. … See more Random events have a probability of occurring that do not depend on the past. While this may not always be true, for many geologic events this is a robust model. For more … See more Recurrence intervals refer to the past occurrence of random events. Forecasting refers to the future likelihood of random events. These are often confused because the recurrence … See more WebJul 30, 1999 · To characterize variability, we computed M from the observed waveforms for each earthquake and measured the recurrence interval, T, for every pair of time-adjacent events in a sequence. These two parameters were averaged for each of the sequences to normalize the M and T values ( Fig. 2 ).
WebNov 16, 2024 · Observations of both natural and laboratory earthquakes demonstrate that the magnitude of stress drop scales with the logarithm of recurrence time, which is a cornerstone of the rate and state friction (RSF) laws. However, the origin of this log linear behavior and short time “cutoff” for small recurrence intervals remains poorly understood.
