Which of the following can result from the reactivation of smaller faults?

The reactivation of smaller faults can indeed lead to major earthquakes because these smaller faults are often segments of larger fault systems. When stress accumulates along these faults due to tectonic forces, they can slip or rupture, resulting in a significant release of energy. This release manifests as an earthquake, which can vary in magnitude depending on the size and characteristics of the fault system involved.

The relationship between fault reactivation and earthquakes is well-documented in geology, where even a small fault under sufficient stress can trigger a large seismic event. The cumulative effects of these events can cause considerable damage to infrastructure and challenges in geological stability. The potential for major earthquakes from smaller fault reactivations underscores the interconnectedness of geological processes and the importance of monitoring such faults in seismically active regions.
