Dear Behzad

Each seismological center can estimate a distance from the center for earthquake center. One circle will give you a location on a circle , 2 circles will give you a lenz and 3 circles will give you an almost tiangle . Then you need at least 3 centers to calculate the very location of the earthquake. Please take a look at picture I sent you.
