For finding the epicenter of an earthquake, you must find the time between the first "P" wave and the first "S" wave. then you must find on page 11 of the reference table where the waves are that many minutes apart and go straight down to find the distance from the epicenter.

To find the epicenter of an Earthquake you first have to find the time difference between the P and S wave. Then you should go to your ESRT and place a dot where the P and S waves are that many minutes apart, and then if you go down from there you will find the distance from the epicenter.

In order to find the epicenter of an earthquake, I need to find the time difference between p wave and S wave. Using ESRT p.11, I need to find a spot on the graph where P and S waves are separated by the time difference. Then, drop straight down to see the distance to the epicenter. Using that distance as a radius, draw a circle. The epicenter is on the circle.

Find the time difference of the P wave and S wave and then use pg11 in the ESRT to find the distance from the epicenter.

You have to find the P wave time and the S wave time then subtract the S wave from the P wave to find the time there is in between the occuring time of the P wave and the S wave. When this is done go to ESRT page 11 and find the point on the graph where the S line and the P line are the number of minutes apart, then go straight down to find the distance from the epicenter.

You have to find the P and S wave times, then you find the difference, then you find the difference on the chart in our ESRT, then you use a map to scale and find the epicenter.

by using to formula to find the epicenter of an earthquake... technically it is correct because you did not ask for the exact formula, only how to find it. HORRAY FOR LOOPHOLES!

To locate an epicenter, you must find the times for the P and S waves, then find the difference between them. Then, using your ESRT pg11, you have to look where the difference of the P and S waves falls on the chart, then draw circles and find the epicenter!...if that makes any sense whatsoever!!

In order to find the epicenter you have to first find the distance of the P and S waves then, locate that time on the ESRT then look at the distance from the epicenter on the bottom of the graph. Using that distance for the middle, you have to draw a circle and the epicenter is on the circle.

To find the epicenter of a earthquake, one would find the distance between the P and S wave. Once that is found, one would go to page 11 in the ESRT. Then one would locate were the P and S waves are separated from each other. Next they would go down to the Xaxis, or the Epicenter distance, to find where the epicenter is

There is no formula Henry. It is a series of steps and that is what I asked for.

First you find the difference between the S wave and the P wave. Since the S wave is always bigger that goes on top. Once you find the difference you use the ESRT and follow the lines.

To find the epicenter, you need to find the distance between the p wave and the s wave. Once you have found this, go on the ESRT to pg 11 and find the distance between the s wave and p wave by the number of minutes apart

To find the epicenter you have to subtract the "S" wave time from the "P" wave time and go down to find the distance to the epicenter. Then you draw a circle and the epicenter is somewhere on the circle

To find the epicenter of an earthquake, you would have to find the difference between the times of the P and S waves. Then look at page 11 of the ESRT and find where the distance between the lines is the difference. Then you would look directly below that point on the xaxis which would show you the epicenter distance.

First you have to find the P and S waves then you have to fun the time and line it up on the ESRT. After this, you should use the scale give to you to find the epicenter.

To find the epicenter of an earthquake, you first have to find the difference in time between the S wave and the P wave. Then you go to page 11 in your ESRT and find the difference on the graph. After that you would use a map to scale and locate the epicenter of an earthquake.

to find the epicenter of an earthquake, you have to find the time difference of the arrival of the P and S waves. You then match up this difference on the curves of the travel time scale and follow down to the bottom of the graph to find the epicenter.

Oooo, i almost forgot to mention that you draw a circle at that point on the graph and the epicenter will be on it.

The way you find the epicenter of an earthquake is by first finding the time difference between the S and P waves. Then you take the time you acquired and find the place on page 11 of the Earth Science Reference Tables where the amount of time between the S and P waves match up with the time you acquired. After you look at the X axis number where you found the spot on the graph and move the decimal three spaces to the right. That number is the distance from the epicenter where the data was received in kilometers.

first you find the time difference between the S and P waves, then you use ESRT pg 11 to find the speed of the waves, and calculate the distance from your location to the epicenter. If you do this for three locations, the spot where the three circles meet should be the epicenter.

To find the epicenter of an earthquake, you first find the time difference between the P and S waves arrival, then you open your ESRT to page 11 to find where the difference fits on the chart, then you find how far away was the epicenter by using the xaxis number that is lined up and lastly you use that number as a radiusto draw a circleon the epicenter map which shows where the epicenter could possibly be.
