Where is the epicenter of an earthquake if the arrival time difference between P and S waves is zero?

Your standing on it!
P-waves travel faster than S-waves through the Earth. As such the further away a seismometer station is from the epicentre of an Earthquake, the larger the difference between arrival times will be. By the same logic this means that the closer you get to the epicentre, the smaller the difference in arrival time will be until your at the epicentre when the difference will be zero!

How is the distance between a seismic station and the earthquake epicenter is determined?
The distance between a seismic station and the earthquake epicenter is determined from the S-P interval, which is the time difference between the time of arrival of the first P wave and the first S wave.
What is the difference between focus - epicenter?
The focus is below ground that is where the earth quake happens. The epicenter is above because that is where it is located
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.
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?
False. The closer you are to the epicentre, the smaller the time difference between the arrival of P and S-waves.
What is the difference between epicenter and earthquake?
An earthquake can reach several miles in distance, but the epicenter is the point of the strongest movement, usually the starting point from which it spreads. Also, the epicentre is on the ground directly above the focus. The focus is the point where the actual earthquake occurred. Hope this helped:)
The distance between a seismic station and the earthquake epicenter is determined from the?
The difference in arrival times of P and S waves.
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.

What is the difference between an earthquake's fucus and epicenter?
An earthquake's focus is the point within the earth where the earthquake starts. The epicenter is the point on earth directly above the focus.
What the difference between a epicenter and a focus?
The difference between the Focus and the Epicenter is...... The Focus is pretty much where the earthquake starts but some people say it is the center of the earthquake. But moving on the Epicenter is right above the Focus but on the crust. I hope that answered your question!!
If there are 3 records of the same earthquake how can the epicenter be determined?
The epicenter can be determined by measuring the time difference between the arrival of P and S waves, and then calculating the distance of the epicenter from each of the 3 stations. Once you have estimated the distance for each station you then draw a circle around each one. The place where the circles meet or intersect, is the epicenter.
What is the difference between epicenter and hypo center?
The epicenter is the origin of an earthquake. However, a hypocenter is the exact spot where a bomb has been dropped.
The distance between an earthquake epicenter and the location of a seismograph can be calculated because?
4. shear waves and compression waves travel at different speeds, therefore the difference in arrival time can be used to fix the distance.
What type of data do geologists use to locate an earthquake's epicenter?
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.

Which two waves from an earthquake can triangulate the epicenter?
P-waves (Primary) and S-waves (Secondary). Using the difference in time between the arrival of P- and S-waves, you can then determine the distance from the epicenter. Once you've determined the distance from the epicenter of three different stations, you'll be able to triangulate the epicenter (the point where all three circles cross).
