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.
Do you really believe that the earth was MILLIONS years OlD???
Scientist just guessed the numbers out. It's funny how people believe them.
Anyways here is what google says: 145 millions years ago.
