Actually, for TRIangulation, you need THREE stations! Two stations will give you 2 intersection points, not just 1.
From Math Central:
"The first initial wave on the seismometer is called the primary (P) wave. The second wave is called the secondary (S) wave. Seismologists measure the interval time of S-P to find the distance from the seismometer to the epicenter. Using three different seismometers, specialists can use the three different distances to find the epicenter using triangulation. "

I would assert that only 2 seismic stations would be enough: during a seism they are specific waves in the soil that have a their own speeds. So if you've got two different points recording the waves activity you may find the epicenter by triangulation.
