Which outcome results when interseismic stress exceeds frictional strength along a subduction zone megathrust fault?

💡 Explanation

When interseismic stress exceeds frictional strength, the fault is locked; elastic rebound occurs because accumulating strain energy is suddenly released when the fault slips, generating seismic waves. Therefore a seismic rupture results, rather than creep, basin spreading, or metamorphism which are characteristic of continuous processes or different plate tectonic settings.
