Definition1/13
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.
