Question

Quizplus · Accepted Answer

The duration of an earthquake is related to the frequency of the seismic waves. Higher frequency waves cause short and sharp shaking whereas lower frequency waves cause longer shaking. Therefore, earthquakes with higher frequency waves will last shorter while earthquakes with lower frequency waves will last longer.
