WebUnderstanding the source of high-frequency ground motion (10-50 Hz) that occurs during an earthquake is not only important from a theoretical standpoint, but from a practical standpoint as well. From the theoretical viewpoint, it can lead to improved understanding of the earthquake-source processes, correct interpretations of seismic data, and ... WebNo, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. That is, the longer the fault, the larger the earthquake. A fault is a break in the rocks that make up the Earth's crust, along which rocks on either side have moved past each other.
