The formula to calculate the return period is:
\[ RP = \frac{1}{P} \]
Where:
An earthquake return period is a statistical measure used to estimate the average time interval between earthquakes of a certain magnitude or intensity occurring in a specific geographic area. It is an important concept in seismic hazard assessment and helps in understanding the likelihood of future earthquakes. The return period is inversely related to the annual probability of occurrence; a shorter return period indicates a higher probability of an earthquake occurring in any given year, while a longer return period indicates a lower probability.
Let's assume the following value:
Using the formula:
\[ RP = \frac{1}{0.05} = 20 \text{ years} \]
The Return Period (RP) is 20 years.
