Question

Quizplus · Accepted Answer

The first motion of P waves can indicate the type of faulting that occurred during an earthquake. For example, if the first motion is a push, it suggests normal faulting. If the first motion is a pull, it suggests reverse faulting. By analyzing the first motion at multiple seismograph stations, scientists can determine the location and orientation of the fault.
