Sections of active fault lines that haven't experienced a significant earthquake for a long time, even though adjacent sections have, are called a. seismic graphs b. seismic risks c. stress accumulations d. recurrence gaps

The options for the given questions are incorrect. The correct options are as follows:

A. seismic gaps

B. seismic risks

C. stress accumulations

D. recurrence gaps

Option (A)

Explanation:

Seismic gaps are usually defined as that part of an active fault that is responsible for the occurrence of tremendous earthquakes and has not taken place for quite a long time. The seismologists look after the data regarding the seismic gaps and predict the occurrence of earthquakes.

It can trigger earthquakes when the amount of accumulated strain below the surface in that particular region is extensively high.

These gaps are located in both the intra-plate boundaries as well as the transform plate boundaries.

Thus, the correct answer is option (A).
