Triangulation. First, they calculate the time between the first and second - primary and secondary - seismic waves created in an earthquake and use this information to determine how far the seismometer is from the epicenter of the earthquake. A circle is drawn around the seismometer so that it is in the center and the radius is equal to the calculated distance. Using this information from three different seismometers, two more circles are drawn and the intersecting point of the three circles is where the epicenter of the earthquake is located.

What is the difference of the P waves and S waves used to locate an earthquake's epicenter?
P waves, also called primary waves, are the first waves to be registered on a seismograph. The S waves, or secondary waves, are the second and slower wave to register on the seismograph. When locating an earthquakes epicenter seismologists take the first reading of the P wave, and then take the reading from the S wave. At the station of where the earthquake was recorded, seismologists draw a large circle from where the earthquakes epicenter could be. TO exactly located the earthquakes epicenter there needs to be at least 3 dfferent staions where the earthquake hit to determine its epicenter using the S and P time interval.
What difference between P-waves and S-waves is used to find an earthquake's epicenter?
The difference in arrival time is used to find the distance to an Earthquake's epicentre.
Can mapping earthquakes help identify faultlines?
Absolutely! There are large concentration of seismic activity (earthquakes) occurring at fault lines which can be used to identify their existence and find their location.
What instrument record earthquakes?
A seismometer is used to measure the strength of earthquakes.
What machine do scientist use to study earthquakes?
The insrument that is used for scientist to study earthquakes is a seismogram
What is is a seismic travel-time curve and how is it used to study earthquakes?
i only know that it is used to measure the distnace from the epicenter
What are seismographs used for?
A seismograph is used to detect vibrations and motions in the Earth's crust. These tremors are usually due to friction between tectonic plates (earthquakes) or huge powerful volcanic activity. - hope that helps
What is the method used to figure out the epicenter of an earthquake?
epicenter and seiesmic waves, find the distance and seismograph stations
How do scientists find the distance to the epicenter of the quake?
they used the focus

A travel-time graph can be used to find?
the distance from a epicenter to an earthquake :)
What can a travel time graph can be used to find?
A travel time graph can be used to find the distance from the epicenter of an earthquake.
What is used to find earthquakes?
Seismograph
A travel-time graph can be used to find the?
The distance of an earthquake epicenter from a seismic station. Using the Three point method, the distance from 3 seismic stations are used to locate the epicenter by triangulation.

What difference between P-waves and S-waves is used to find an earthquake's epicenter?
The difference in arrival time is used to find the distance to an Earthquake's epicentre.
Whats the difference between the epicenter of an earthquake and the focus of the earthquake?
The focus of an earthquake is the place where an earthquake occurred along the fault underground, while the epicenter is the place directly above it where the seismic waves were felt.The focus is where an earthquake starts and the epicenter is where the earthquake hits the hardest.The focus of the earthquake is where the actual earthquake occurred and the epicenter is on the ground directly above the focus. The epicenter is used to say where the earthquake was in relation to places near where it occurred.
