Why do you need three seismic to find epicenter of an earthquake?

Triangulation for accuracy.
The method is called "triangulation" ... same method used by GPS units to coordinate the exact locations.
Please see the related question for more information.

What is the number of seismic stations need to find the epicenter of an earthquake?
Technically you just need one, but the more there are, the easier it is to locate the epicenter of the earthquake. The reason for this is that based on the timing of each of the three seismic waves that reach the station, the station can calculate a radius all around the station. So picture a circle with what the radius is around the station, another station will do the same thing, and there HAS TO BE an intersection of these circles somewhere, so that narrows down the location of the epicenter. Hope this makes sense.
What is the method used to figure out the epicenter of an earthquake?
epicenter and seiesmic waves, find the distance and seismograph stations
How many seismograph data points are required to locate an earthquake's epicenter?
At least 3 stations are required to find the epicenter
How do p and s waves provide the location of the earthquake's epicenter?
you have to find the s and p to find and then you have the awnser
What are Seismic hazard maps used?
When building a house, regional seismic hazard maps are used to find the best (or the worst) place to locate for earthquake shaking. Although greatly confused with its sister, seismic risk, seismic hazard is the study of expected earthquake ground motions at any point on the earth.
A travel-time graph can be used to find the?
The distance of an earthquake epicenter from a seismic station. Using the Three point method, the distance from 3 seismic stations are used to locate the epicenter by triangulation.

What waves do scientists use to find an earthquake's epicenter?
seismic waves
How do you find the epicenter of an earthquake by seismic data?
By finding the arrival time of the P waves and S waves :)
What is the process that is used to find an earthquake's epicenter?
Triangulation. First, they calculate the time between the first and second - primary and secondary - seismic waves created in an earthquake and use this information to determine how far the seismometer is from the epicenter of the earthquake. A circle is drawn around the seismometer so that it is in the center and the radius is equal to the calculated distance. Using this information from three different seismometers, two more circles are drawn and the intersecting point of the three circles is where the epicenter of the earthquake is located.
Where are seismographs located?
At many different earthquake centers. When an earthquake happens the tree nearest earthquake centers record the magnitude and intensity of the seismic waves produced by the earthquake in order to find the origin or epicenter
How do you use triangulation to find an epicenter of an earthquake?
the find the epicenter the find the focus from the epicenter
What is needed to find the epicenter of an earthquake?
You are suppose to pin point the three circles

Why is three the minimum number of stations necessary to locate an epicenter?
Three seismic stations are needed to find the epicenter of an earthquake because all three radial circles made by the stations will only meet at one point. (example: if you only had to circles they would meet at two different points)At least 3
How do geologist locate the epicenter of an earthquake?
This job would normally be undertaken by a type of geophysicist known as a seismologist rather than a geologist. For information on how seismologists locate seismic waves, see the related question.
Where earthquake geographic location?
the epicenter of the earthquake is where the earthquake hit. technically, you need three epicenters the find where the earthquake actually hit, though. Edit: The epicenter is the location on the surface traced to by seismographs for people to get an idea of where the earthquake happened. The hypocenter is where the earthquake actually happened below the surface.
