How can the epicenter of an earthquake be located miles away from the fault line?

The epicenter of an earthquake is the point on the Earth's surface directly above where the earthquake originates, known as the focus or hypocenter. Due to the complex nature of tectonic plate interactions and the propagation of seismic waves, the epicenter can be located miles away from the fault line where the movement occurs. Factors such as the angle of the fault and the geological characteristics of the surrounding area can influence the distance between the fault line and the epicenter. Additionally, seismic waves can travel through different materials at varying speeds, causing the location of the epicenter to be determined based on the arrival times of these waves at monitoring stations.
