Why is it important to know the epicenter of an earthquake

Finding the epicenter leads to the determination of the fault that caused the earthquake.

If the fault is already known, the data is used to increase confidence for building techniques in the area.

If the fault is previously unknown, it is important because it means that the structural design techniques in the area need improvement to remain safe and effective.

Improving the hazard modeling keeps buildings and people safe.
