At least two, or a minimum of three.
The minimum number of seismographs needed to locate an epicenter of an earthquake is 3.
The minimum number of seismic stations needed to determine the location of an earthquake's epicenter is THREE.
The minimum number of seismic stations needed to determine the location of an earthquake's epicenter is THREE.
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 stations would best pinpoint the epicentre by triangulation.

3 stations
Three seismograph stations are needed to determine the location of an epicenter because each seismograph can determine distance to the epicenter but not direction. The point where the three circles intersect is the epicenter of the earthquake. +++ Focus - not epicentre, which is the point of maximum movement on the surface above the slip itself.
