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.
They have evolved to endure more as well as having been exposed to it from birth.

Answer:
Option (A)
Explanation:
Trenches are usually defined as deep and narrow depressions that are formed along the convergent plate boundaries. These are the region where two tectonic plates move towards each other and result in the formation of a subduction zone, where the denser plate subducts below the less dense one. As the heavier plate goes down, it reaches the mantle and the rocks undergo partial melting.
These trenches are located just above this zone of subduction. It can also be said that the presence of a trench indicates a subduction zone.
One of the famous trenches is the Mariana trench which is present in the Pacific ocean and it has a depth of approximately 11 km from the mean sea level.
Thus, the correct answer is option (A).
