The distance between a seismic station and the earthquake epicenter is determined from the?
The difference in arrival times of P and S waves.
Is data about an earthquake from two seismographic stations enough information to locate the epicenter?
From Science Explorer Prentice Hall Earth Science: " Geologists use seismic waves to locate an earthquake's epicenter. Seismic waves travel at different speeds. P waves arrive at a seismograph first, with S waves following close behind. To tell how far the epicenter is from the seismograph, scientists measure the difference between the arrival time of the P waves and S waves. The farther away an earthquake is, the greater the time between arrival of the P waves and the S waves." Did this help?
How do you find the epicenter of an earthquake by seismic data?
By finding the arrival time of the P waves and S waves :)
How do you use circles to find the epicenter of an earthquake?
Scientists can calculate the distance that an earthquake occurs from a seismometer station by looking at the record of the seismic waves and measuring the difference in time between the arrival of P and S-waves. This gives them a distance but not a direction. So they plot this distance on a map by drawing a circle round the seismometer station. The radius of this circle is equal to the distance to the epicentre. If this is done for one other seismometer station that has recorded the earthquake then the circles will intersect in two places. If you add in a 3rd station and so a third circle they will all intersect in one place - the epicentre of the earthquake. In reality this process is automated by computer and lots of readings from lots of stations are used.
What do geologists use to locate a earthquakes epicenter?
The S-P time method is perhaps the simplest method seismologists use to find an earthquake's epicenter. +++ No it's not. That finds its Focus. The Epicentre is the point of maximum movement on the land surface above the slip itself.

The distance between a seismic station and the earthquake epicenter is determined from the?
The difference in arrival times of P and S waves.
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.

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).
How do you find the epicenter of an earthquake by seismic data?
By finding the arrival time of the P waves 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.
How do seismographs approximate the location o an epicenter?
The farther apart the arrival times of the different waves are, the farther away the earthquake is. :)
Can the s-p time method be used with one seismograph station to locate the epicenter of an earthquake?
The first step in this method is to collect several seismograms of the same earthquake from different locations. Then, the seismograms are placed on a time-distance graph. The seismogram tracing of the first P wave is lined up with the P-wave time-distance curve, and the tracing of the first S wave is lined up with the S-wave curve.The distance of each station from the earthquake can be found by reading the horizontal axis. After finding out the distances, a seismologist can locate an earthquake's epicenter.-New Boyz
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.
