Answer:
The minimum number of seismograph stations that would be needed to accurately locate an earthquake epicenter would be three.
Step-by-step explanation:
There will only be three for the minimum amount because eventually they intersect. Circles have to be intersected within three places due to triangulation. Triangulation needs to be involved in order to determine the wave traveled location, which locates the epicenter of an earthquake. Each of the circles radius can be the distance known to the epicenter.
