True. The farther apart the P (primary) and S (secondary) waves appear on a seismogram, the greater the distance from the seismograph to the epicenter of the earthquake. This is because P waves travel faster than S waves, and the time difference between their arrivals can be used to calculate the distance to the epicenter.
The farther apart the P and S waves are on a seismogram, the farther away is the epicenter of an earthquake.
