WebEnergy and Numbers. The energy of an earthquake is proportional to the amplitude squared. In theory, the energy of an earthquake of surface wave magnitude n is equivalent to approximately 100 earthquakes of surface wave magnitude n-1. In reality, the energy is only about 30 times greater and the shaking is only about 10 times greater in intensity. WebActive fault. An active fault is a fault that is likely to become the source of another earthquake sometime in the future. Geologists commonly consider faults to be active if there has been movement observed or evidence …
