surface waves
The distance between a seismological recording station and the earthquake source is determined from the arrival times of seismic waves at the station. By comparing the arrival times of P-waves and S-waves, seismologists can calculate the distance to the earthquake source using the difference in their arrival times.
The lag time between the arrival of primary (P-wave) and secondary (S-wave) seismic waves increases with distance from an earthquake's epicenter. This relationship is due to the differing speeds at which these waves travel through the Earth's layers. By measuring this lag time, scientists can estimate the distance to the earthquake's epicenter.
The time difference in arrival between P and S waves can help determine the distance to an earthquake epicenter. For each second of difference, the earthquake is roughly 7.5 kilometers away. So, a time difference of, for example, 10 seconds would indicate the earthquake is approximately 75 kilometers away.
As the distance to the epicenter increases, the time difference between the arrival of P and S waves also increases. This is because S waves travel at a slower speed than P waves and take longer to reach a seismograph station. The lag between the two waves can be used to determine the distance to the earthquake epicenter.
The distance from an earthquake epicenter can be calculated using the time difference between the arrival of P-waves and S-waves at a seismograph station. By measuring this time lag and using the known velocity of seismic waves through the Earth's interior, the distance can be estimated. The greater the time lag between the arrival of the P-wave and S-wave, the farther the seismograph station is from the earthquake epicenter.
The difference between the arrival times increases as the distance from an earthquake epicentre increases as S-waves travel more slowly than P-waves so the greater the distance the further they lag behind.

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.

The distance between a seismological recording station and the earthquake source is determined from the arrival time of P and the S waves. P waves are faster than S waves and surface waves.
False. The closer an earthquake is, the shorter the time difference between the arrival of P waves and S waves. P waves travel faster than S waves, so the time interval decreases as the distance to the earthquake epicenter decreases.
