To locate the epicenter you use the speed of waves that travel from the epicenter to the seismic sensor locations. With two sensors you are able to narrow the location to two places (when on a surface using intersecting hyperbolas). With a third sensor you have the location on a surface and below ground. This third sensor is why they call it tri - angulation but the angles are hard to find without HS trigonometry and other mathematics.

How do you use triangulation to find an epicenter of an earthquake?
To find the epicenter of an earthquake using triangulation, seismologists analyze the arrival times of seismic waves at three or more seismic stations. By comparing the differences in arrival times, they can determine the distances from each station to the epicenter. By drawing circles with the stations as the center and their respective distances as the radius, the intersection of these circles represents the estimated epicenter of the earthquake.
What method is used by scientists to locate the epicenter of an earthquake?
Scientists use a method called triangulation to locate the epicenter of an earthquake. By analyzing the arrival times of seismic waves at multiple seismograph stations, they can determine the distance from each station to the epicenter. The intersection of these distance measurements helps pinpoint the epicenter location.
What is the method that scientists use to determine the epicenter of an earthquake?
Scientists use a technique called triangulation to determine the epicenter of an earthquake. This method involves analyzing seismic waves recorded at three or more different locations to pinpoint the exact location where the earthquake originated. By comparing the arrival times of these waves at different seismograph stations, scientists can calculate the distance from each station to the epicenter and then use that information to triangulate the exact location.
How do you figure out the distance of an epicenter?
To determine the distance of an epicenter, you can use the difference in arrival times between the P-wave and S-wave on a seismogram. By comparing these arrival times and using a travel-time graph, you can estimate the distance from the seismic station to the epicenter.
Why might the triangulation method not always produce an exact point for an epicenter?
The triangulation method may not always produce an exact point for an epicenter because it relies on accurate and precise timing of seismic wave arrivals at different stations. Errors in measuring arrival times, variations in seismic wave velocity, and limited number of monitoring stations can result in uncertainties that affect the accuracy of the calculated epicenter point.
