What information can you get about earthquakes location from only two seismic stations data?

Answer:

From only two seismic stations data we can get the direction from which the Earthquake originated.

Explanation:

When the information taken into consideration from only one station, it tells us about the epicenter of the earthquake could at any point on that circle. when the information comes from two stations, the circles intersect at  2  points, so there are possibility  of having two epicenters. With three stations, the circles intercept at only one point, which must be the epicenter. The sesmic station present in the network helps in measuring the movement of plates from the ground motion. the signature sesmograph tells us about the bigger earthquakes.
