By using seismographs and scales

They Use A Seismograp and look at the squiggles on the paper.
Three seismographs stations are needed to pinpoint the location of the epicentre of an earthquake.
Geologists use circles to find the epicenter of an earthquake.
The point is the epicentre of the earthquake.
yes it can
This job would normally be undertaken by a type of geophysicist known as a seismologist rather than a geologist. For information on how seismologists locate seismic waves, see the related question.
No. A minimum of three seismometer stations are required to locate an earthquakes epicentre. Please see the related question for more information.
Its epicentre
The underground centre of an earthquake is the Hypocentre or focus.
The epicentre of an earthquake is the point on the earth's surface away from which the seismic waves produced by an earthquake radiate. This is similar to the way waves or ripples in a pond move outwards in concentric circles from the point where you throw a stone into the water. As such the epicentre is the point on the earth's surface directly above the earthquake's focus or hypocentre (the point within the earth where the fault rupture or movement actually occurs).
Seismologists use the data from triangulated seismographs to locate an earthquake's epicenter. The difference in time between the arrival of p and s waves at a seismometer tells the distance to the epicenter of an earthquake. To get the exact location, scientists must collect data from at least three seismometers. The point where all three circles is the epicenter of the earthquake. +++ The Epicentre is generally obvious: it is the point of maximum disturbance on the surface. The centre of the actual slip is the Focus, and this has to be calculated from seismograph data by triangulating from wave velocities.
