Can geologists use data from two seismograph stations to locate an earthquakes epicenter?
yes it can
The distance between an earthquake epicenter and the location of a seismograph can be calculated because?
The time it takes for seismic waves to reach the seismograph can be used to calculate the distance between the epicenter and seismograph. By knowing the average speed of seismic waves in the earth, the time difference between the arrival of P- and S-waves can be used to determine the distance.
When an earthquake occurs data from one seismograph can tell you what?
When an earthquake occurs, data from one seismograph can tell you the arrival time of seismic waves, the distance from the earthquake epicenter to the seismograph, and the magnitude of the earthquake. By analyzing this data, scientists can determine the location and strength of the earthquake.
How do geologist locate the epicenter of an earthquake?
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.
How do you locate the epicenter of an earthquake?
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.
Do Geologists use the difference in the arrival time of P and S waves at a seismograph to determine the magnitude of an earthquake?
No. Seismologists (a type of geophysicist) use the difference in the arrival time of P and S waves to estimate the distance from the seismometer station to the epicentre of the earthquake.

What can geologists meassure to tell how far an earthquake's epicenter is from a particular seismograph?
Geologists can measure the time difference between the arrival of primary (P) waves and secondary (S) waves at a seismograph to determine the distance to an earthquake's epicenter. Since P waves travel faster than S waves, the longer the time interval between their arrivals, the farther the epicenter is from the seismograph. By using this time difference along with established seismic wave speeds, geologists can calculate the distance to the epicenter. This distance can then be plotted on a seismographic map to pinpoint the location of the earthquake.

How is the fact that P waves travel more quickly the S waves used to determine the distance of an earthquake's epicenter from a seismograph station?
The time difference between the arrival of P waves and S waves at a seismograph station is used to determine the distance of an earthquake's epicenter. By measuring this time lag and knowing the speed at which each wave travels through the Earth's interior, scientists can calculate the distance the waves traveled to reach the station. The farther apart the arrival times of P and S waves, the greater the distance of the epicenter from the station.
What are the steps of the S-P time method?
The S-P time method is used to determine the distance to an earthquake epicenter. The first step is to measure the time difference between the arrival of the primary (P) waves and the secondary (S) waves at a seismograph station. The second step is to use a travel-time graph to determine the distance to the epicenter based on the time interval between the P and S waves. Finally, by using data from at least three seismograph stations, the exact location of the earthquake epicenter can be triangulated.

How do you locate the epicenter of an earthquake?
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.
How to locate the epicenter of an earthquake?
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 different seismograph stations, they can pinpoint the epicenter where the seismic waves originated.
Is it true that the closer an earthquake the greater the time difference between the arrival of P-waves and the arrival of S-waves?
Yes, that is correct. The time difference between the arrival of P-waves and S-waves increases as the earthquake epicenter gets closer to the seismograph. P-waves are faster, so they arrive first, followed by the slower S-waves.
How is the fact that P-waves travel faster that S-waves used to determine the distance of an earthquake epicenter from an seismograph station?
Using the difference in their arrival times and an estimate of their velocity of propagation you can calculate the distance of the earthquake epicentre from the seismometer recording station. If you do this from three or more different seismometer stations you can triangulate it's position. For more information please see the related question.
