D) the average time of recovery following a hazardous event.

Question

Quizplus · Accepted Answer

The recurrence interval or return period refers to the average time between two hazardous events of the same magnitude. It is based on statistical analysis and helps to estimate the likelihood of a hazardous event occurring in a given time period. Option B is incorrect as it refers to the probability of an event occurring within a specific timeframe, whereas the recurrence interval considers the time between two events. Option C is also incorrect as it refers to the maximum time between two events, which may not be representative of the actual frequency of the events. Option D is unrelated to the concept of recurrence interval.
