It is recorded from three differences because you can do two tests and they can meet at one spot but it may not be the actual epicenter. They do the third test to be ssure they have the right spot or epicenter.
To determine the epicenter of a hypothetical earthquake, you need specific information about the earthquake, such as the locations of seismic stations that detected the tremors and the time it took for the seismic waves to reach those stations. By analyzing the data from at least three different seismic stations, geologists can triangulate the epicenter's location. Without specific details or coordinates, it's not possible to identify the epicenter accurately.
At least three seismic stations are needed to compare results and determine the epicenter of an earthquake using the method of triangulation. By measuring the arrival times of seismic waves at different stations, scientists can pinpoint the epicenter where the waves intersect.
To locate an earthquake epicenter, data from at least three seismic stations are needed to triangulate the position. Each station records the arrival times of seismic waves (P-waves and S-waves), allowing for the calculation of the distance from each station to the epicenter. By plotting these distances on a map, the point where the circles intersect indicates the epicenter's location. This method relies on the differences in arrival times of seismic waves at each station to determine their respective distances.
Properties such as the arrival times of seismic waves at different seismic stations, the difference in arrival times between primary (P) and secondary (S) waves, and the directionality of the seismic waves can help seismologists locate the epicenter of an earthquake. By analyzing these properties, seismologists can triangulate the epicenter by determining the intersection point of the circles of possible epicenter locations based on seismic wave arrival times.
Like a polyghraph squiggles show the techtonic plates moving.
The epicenter of an earthquake can be determined by analyzing the arrival times of seismic waves recorded by seismometers at different locations. By comparing the arrival times, scientists can triangulate the epicenter where the seismic waves originated.
To locate the epicenter of an earthquake, scientists use data from seismographs to determine the difference in arrival times of seismic waves at different locations. By triangulating this data from at least three seismograph stations, they can pinpoint the epicenter where the seismic waves originated.

The position on the Earth's surface directly above the earthquake source is called the epicenter. This is where the seismic waves originate and where the shaking is usually strongest. Scientists use the epicenter location to determine where an earthquake occurred.

3. With 2 you can get possible locations (where the 2 circles intersect). With the 3rd reading, that circle will intersect the other two circles at one of those 2 candidate locations. See the link for a description.http://www.geo.mtu.edu/UPSeis/locating.html
To locate the epicenter you use the speed of waves that travel from the epicenter to the seismic sensor locations. With two sensors you are able to narrow the location to two places (when on a surface using intersecting hyperbolas). With a third sensor you have the location on a surface and below ground. This third sensor is why they call it tri - angulation but the angles are hard to find without HS trigonometry and other mathematics.
The simplified answer is that it works much in the same way you would determine the source of a sound (which is also in waves). Multiple measurements of the intensity are taken from different locations are used to triangulate an earthquake.
