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:
[tex] [(820 - 260) + (1200 - 820) + (2100 - 1200) + (2300 - 2100)] / 4 [/tex]
[tex] = (560 + 380 + 900 + 200) / 4 [/tex]
[tex] = 2040/4 = 510 [/tex]
After the calculations, the recurrence interval of the earthquake that caused the disruption is 510 years.
