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

= (560 + 380 + 900 + 200) / 4

= 2040/4 = 510

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

What are the positive and negative effects of geological structures in our environment?
Marrrta [24]
The negative effects of geological structures in our environment can be landslides occurring on unfavorably oriented geological structures causing damage and sometimes loss of life on highways and railways, for example.A positive effect of geological structures is that where there are subduction zones, mineral deposits can form above them on the adjoining continents like in British Columbia on the west coast of North America. Also, faults and fractures can allow hydrothermal fluids charged with metals to form ore deposits.
