Answer:
510
Explanation:
Recurrence interval involves the average estimated time or average spacing between events. It helps to estimate the time probability of an event taking place.
Calculating the recurrence interval we have:
![[(820 - 260) + (1200 - 820) + (2100 - 1200) + (2300 - 2100)] / 4](https://tex.z-dn.net/?f=%20%5B%28820%20-%20260%29%20%2B%20%281200%20-%20820%29%20%2B%20%282100%20-%201200%29%20%2B%20%282300%20-%202100%29%5D%20%2F%204%20)


After the calculations, the recurrence interval of the earthquake that caused the disruption is 510 years.
