Question

Examining sedimentary bedding (layers of rock or sediment) in a geologic study reveals disrupted layers formed 260, 820, 1,200, 2,100, and 2,300 years ago. What is the recurrence interval of the earthquakes that caused the disruption

Answer 1

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.
