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.
At least three seismic stations are needed to locate an earthquake's epicenter using the triangulation method. By measuring the time it takes for seismic waves to reach each station, scientists can pinpoint the epicenter where the three circles intersect.
To accurately locate the epicenter of an earthquake, data from at least three seismographic stations is required. Each station provides a different distance measurement from the epicenter based on the arrival times of seismic waves. By using these distances, the intersection points can be calculated, pinpointing the exact location of the earthquake's epicenter.
I believe that minimum number would be three.
That depends on what information you are interested in. A single seismic station station measuring the P and S-wave arrival time can make an estimate of the distance to the epicentre of the earthquake and based on this information and the amplitude of the measured waves can make an estimate of the earthquakes magnitude, whereas a minimum of three stations are needed to find the location of the epicentre. For more information on this process, please see the related question.
The energy released by an earthquake is measured using a seismometer. The amplitude of the seismic waves recorded by a seismometer are in-turn plugged into an equation that gives a value on the magnitude scale.

you need to have 3 seismic stations to triangulate the location of the earthquake and remember a earthquake can be from the inside of the earth but not necessarily at the epicenter because no epicenter is a straight line down.
Three seismograph stations are needed to locate the epicenter of an earthquake. By measuring the arrival times of seismic waves at three different stations, scientists can use triangulation to pinpoint the earthquake's epicenter.
A minimum of three seismograph stations are needed to triangulate and accurately locate the epicenter of an earthquake. By measuring the arrival times of seismic waves at the stations, the intersection of three circles of possible epicenter locations can pinpoint the exact location where the earthquake originated.

Oh, dude, so like, when it comes to locating an epicenter, you need at least three stations because, like, each station gives you a radius of possible locations. And when you have three stations, those circles intersect at two points, which narrows down the possible epicenter locations. It's like triangulation, but with earthquakes instead of maps.
