What happens to the distance in arrival times between P waves and S waves as the distance from an earthquake increases?
As the distance from an earthquake increases, the time difference between the arrival of P waves and S waves remains constant. This is because P waves (primary waves) travel faster than S waves (secondary waves), regardless of the distance. While both waves travel outward from the epicenter, the speed difference ensures that the interval between their arrivals does not change, allowing seismologists to determine the distance to the earthquake's epicenter based on this consistent time gap.
If the time between p and s waves are 430 what is the distance to epicenter?
The distance to the epicenter can be calculated using the formula that relates the time difference between P-waves and S-waves to the distance. The typical formula is Distance (in kilometers) = Time difference (in seconds) × 8. For a time difference of 430 seconds, the distance to the epicenter would be approximately 3,440 kilometers.
How could you tell which two observers was farther from an earthquake epicenter by comparing the arrival times of p and S waves for the two locations?
To determine which observer is farther from an earthquake epicenter, you can compare the arrival times of P (primary) waves and S (secondary) waves at each location. P waves travel faster than S waves, so the time difference between their arrivals increases with distance from the epicenter. By analyzing the time difference for each observer, the location with the greater time gap indicates a farther distance from the epicenter. The greater the delay in S wave arrival after the P wave, the farther the observer is from the epicenter.
How could you tell which of two observers was farther from an earthquake epicenter by comparing the arrivaltimes of p and s waves for the two locations?
To determine which observer is farther from an earthquake epicenter, you can compare the arrival times of P-waves (primary waves) and S-waves (secondary waves) at each location. P-waves travel faster than S-waves, so the difference in their arrival times increases with distance from the epicenter. By measuring the time difference between the arrivals of these waves at each observer's location, you can calculate the distance to the epicenter; the observer with the larger time difference will be farther from the epicenter.
What happens to the lag time as distance from the epicenter increases?

As the distance from the epicenter increases What happens to the time lag between p and s wave?
As the distance from the epicenter increases, the time lag between P and S waves increases. This is because the P wave, being faster, arrives at the seismograph station sooner than the S wave which is slower. The greater the distance, the more noticeable this time lag becomes.
What happens to a graph of time and distance as speed increases?
The graph of distance vs time increases exponentially as speed increases.
How does distance from the epicenter affect the s-p waves time interval?
The distance from the epicenter affects the S-P wave time interval because seismic waves travel at different speeds. P-waves (primary waves) are faster than S-waves (secondary waves), so as the distance from the epicenter increases, the time gap between the arrival of the P-wave and S-wave (the S-P time interval) also increases. This time interval is used to calculate the distance to the earthquake's epicenter, allowing seismologists to locate it accurately. Thus, a greater distance results in a longer S-P time interval.
When the distance to the epicenter increases how does the amount by which the s waves lags behind the p wave change?
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.
What is the relationship between lag time and distance from an earthquake's epicenter?
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.
If the time between p and s waves are 430 what is the distance to epicenter?
The distance to the epicenter can be calculated using the formula that relates the time difference between P-waves and S-waves to the distance. The typical formula is Distance (in kilometers) = Time difference (in seconds) × 8. For a time difference of 430 seconds, the distance to the epicenter would be approximately 3,440 kilometers.
Why does the time between the arrival of the p waves and the s waves become greater and greater as you travel farther away from the epicenter?
The time difference between P waves and S waves increases with distance from the epicenter because P waves, which are primary waves, travel faster than S waves, which are secondary waves. As seismic waves propagate through the Earth, the greater the distance from the epicenter, the longer it takes for the slower S waves to arrive after the faster P waves. This results in a growing time interval between their arrivals, allowing seismologists to determine the distance to the epicenter based on this time difference.
Does the lag time get shorter or longer the further you get from the epicenter?
The lag time between the arrival of P-waves and S-waves generally gets longer the further you are from the earthquake's epicenter. P-waves travel faster than S-waves, so the time difference between their arrivals increases with distance.
What is a travel-time curve used for?
To measure the distance from the epicenter.
How do you figure out the distance of an epicenter?
The distance of an epicenter from a seismograph station can determined by the time it takes for the seismic waves to reach each station. You need at least 3 seismic stations to record the event to determine this. The time taken for each seismic station to resisted the event will be different as they are different distances from the epicenter. The distance to the epicenter can then be calculated for each station and a epicenter can be determined by a triangulation from all stations that have registered the event.
