The minimum number of seismographs needed to locate an epicenter of an earthquake is 3.
At least two, or a minimum of three.
No. A minimum of three seismometer stations are required to locate an earthquakes epicentre. Please see the related question for more information.
From Science Explorer Prentice Hall Earth Science: " Geologists use seismic waves to locate an earthquake's epicenter. Seismic waves travel at different speeds. P waves arrive at a seismograph first, with S waves following close behind. To tell how far the epicenter is from the seismograph, scientists measure the difference between the arrival time of the P waves and S waves. The farther away an earthquake is, the greater the time between arrival of the P waves and the S waves." Did this help?
A seismograph can locate a seismic wave.

yes it can
At least 3 stations are required to find the epicenter
The minimum number of seismic stations needed to determine the location of an earthquake's epicenter is THREE.
A minimum of three seismic stations must compare results to locate an earthquakes epicenter.
At least two, or a minimum of three.
At least three.Please see the related question for an explanation as to why.A minimum of three seismograph or seismometer stations are required to locate the epicentre of an earthquake.

The first step in this method is to collect several seismograms of the same earthquake from different locations. Then, the seismograms are placed on a time-distance graph. The seismogram tracing of the first P wave is lined up with the P-wave time-distance curve, and the tracing of the first S wave is lined up with the S-wave curve.The distance of each station from the earthquake can be found by reading the horizontal axis. After finding out the distances, a seismologist can locate an earthquake's epicenter.-New Boyz
