Which mechanism causes long-term cyclic uplift and subsidence along a strike-slip fault zone?

💡 Explanation

When stress accumulates along a locked strike-slip fault, elastic strain builds up because friction prevents immediate slip; this strain is then released cyclically during earthquakes, causing localized uplift and subsidence. Therefore, elastic strain accumulation and release accounts for the periodic vertical movement observed, rather than erosion, deposition, or mantle convection.
