When seismic waves hit a fault, the waves are reflected off the fault.Seismograph can detect these reflected seismic waves.Geologists then use these data to map the fault's length and depth.

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.
Scientists can use seismograph data to locate the focus of an earthquake
yes it can
To locate the epicenter of an earthquake, scientists use data from seismographs to determine the difference in arrival times of seismic waves at different locations. By triangulating this data from at least three seismograph stations, they can pinpoint the epicenter where the seismic waves originated.
A seismograph is the device that scientists use to measure earthquakes. The goal of a seismograph is to accurately record the motion of the ground during a quake

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.
yes ; I am a geologist
