why or why not?

No, recording stations can only detect the distance to the epicentre, not direction. This creates a circle on the globe of possible epicentres surrounding that recording station. With two circles from two recording stations, they will probably overlap in two places, creating uncertainty. Three or more is needed to give a good amount of certainty to an epicentre.
The guy below me doesnt realize that earthquake recording stations dont get vectors.

I have developed a method by which you can locate the epicenter from single station. Of course it is approximate and just enough to issue the Tsunami warning. I am the man in India issued the warning 2 hours before Tsunami struck our coast. The people at T.V.Stations refused to telecast my warning. By the use of the direction finder together with seismograph you can locate the epicenter. Now the seismologists are drawing three circles according the distance of epicenter and the imaginary meeting point is the epicenter. When you use my direction finder you can find the direction of epicenter. You can draw a line from the recording station to the periphery of the circle already drawn with the data available from single seismograph. The meeting point is the epicenter. Ancient Chinese were having this type of instrument. The one I have developed is an electronic instrument. If I increase the number of the sensors for the directions ( Now I have used eight ) I can get more accurate result. Our Indian government not yet recognized my inventions.You will get two probable points when you use 2 seismiograph. Pleas visit my URL to know more on this

In the absence of any other information, data from two seismographs will give you 2 possible locations for the earthquake centre. You would need data from a third station to pinpoint it exactly..

Yes, you can. It's called triangulation. Old forest towers used to spot fires with the same technology.
Get a vector on the strongest signal from two known points, and you can use trigonometry to find the source.
Of course, more known points would reveal better results.

A two-point solution always will have two potential answers.
It is possible but not likely that more than two points could also give two potential results. Used to have that problem on occasion using range-range-range C-band radar positioning systems. But you also usually have a pretty good idea which of the two solutions is most likely correct.

No. Triangulation requires three (hence, the prefix tri) stations.
