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.

I believe that minimum number would be three.
There are a number of features of an earthquake. The main features include vibration of the earth surface, possible destruction of buildings and property, movement of tectonics under the surface of the earth and so much more.
The strength of an earthquake is measured using a seismic scale called the moment magnitude scale (Mw). It calculates the total energy released by an earthquake by measuring the amplitude of seismic waves. The scale is logarithmic, meaning that each whole number increase represents a tenfold increase in magnitude and roughly 31.6 times more energy released.
The Richter scale provides a measure of the magnitude or energy released by an earthquake. It quantifies the amplitude (size) of seismic waves generated by the earthquake, which correlates with the earthquake's strength. The scale is logarithmic, meaning that each whole number increase on the scale represents a tenfold increase in the amplitude of shaking and approximately 31.6 times more energy release.

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.

The minimum number of seismographs needed to locate an epicenter of an earthquake is 3.
Three seismographs stations are needed to pinpoint the location of the epicentre of an earthquake.
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
