The difference between the two seismograph readings could tell you where the epicenter is located.

It is necessary to know thedistance from the epicenter for at least three recording stations so, geologist could compare better and when an epicenter is created they can know which one is the farthest and which one is the closest.
This is the point on the earth's surface directly above the hypocentre of the earthquake. As such the seismic waves have traveled a minimum distance and so there has been a minimum dissipation of energy. This means they have retained the majority of their energy and so are able to cause the most damage.
Seismographs have been used on the moon. Specifically they have used for learning about the moon's and Earth's evolution, understanding Earth's seismology with comparative studies, and gaining knowledge about tidal moonquakes or other origins of these forces.
It could be at a very high altitude.

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.
how do seismologist know how to find the location of a epicenter
A city near the epicenter is not safe because an earthquake could happen right at the epicenter.
The seismograph was important to ancient china because it could detect an earthquake and warn people so they could escape.

seismic activity, I think
seismograph is one instrument that could measure earthquakes and volcanoes etc but seismograph is many times use at earthquake!
it is necessary to kow the distance from the epicenter for at least three recording stations so geologist could compare and when an epicenter is created they can know which one is farest and which one is closest
there are differences in readings for many reasons. it could be the environment affecting the experiment, the equipment may be faulty or the method of measurement may be incorrect
