Do Geologists use the difference in the arrival time of P and S waves at a seismograph to determine the magnitude of an earthquake?
No. Seismologists (a type of geophysicist) use the difference in the arrival time of P and S waves to estimate the distance from the seismometer station to the epicentre of the earthquake.
Is it true that the closer an earthquake the greater the time difference between the arrival of P-waves and the arrival of S-waves?
False. The closer you are to the epicentre, the smaller the time difference between the arrival of P and S-waves.
Which of the following can cause damage days or month after a large earthquake?
the arrival of surface waves liquefaction a tsunami an aftershock
Where is the epicenter of an earthquake if the arrival time difference between P and S waves is zero?
Your standing on it! P-waves travel faster than S-waves through the Earth. As such the further away a seismometer station is from the epicentre of an Earthquake, the larger the difference between arrival times will be. By the same logic this means that the closer you get to the epicentre, the smaller the difference in arrival time will be until your at the epicentre when the difference will be zero!
What happens to The difference in arrival times between p waves And s waves as The distance From the earthquake increase?
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.
How can the arrival and progress of an eathquake be recognized on a seismogram?
by wavy lines of characteristic shapes
What can cause damage days or months after an earthquake?
Earthquake aftershocks.the arrival of surface waves
Is it true or false that the closer an earthquake the greater the time between the arrival of P waves and the arrival of S waves?
true
How can you calculate the origin time of an earthquake?
arrival time-travel time
The distance between a seismic station and the earthquake epicenter is determined from the?
The difference in arrival times of P and S waves.

No. Seismologists (a type of geophysicist) use the difference in the arrival time of P and S waves to estimate the distance from the seismometer station to the epicentre of the earthquake.
Is it true that the closer an earthquake the greater the time difference between the arrival of P-waves and the arrival of S-waves?
False. The closer you are to the epicentre, the smaller the time difference between the arrival of P and S-waves.
What difference between P-waves and S-waves is used to find an earthquake's epicenter?
The difference in arrival time is used to find the distance to an Earthquake's epicentre.
How do seismologists determine an earthquake's starting time?
To calculate an earthquake's starting time, seismologists compare seismograms and note the differences in arrival times of P and S waves.
How do you find the epicenter of an earthquake by seismic data?
By finding the arrival time of the P waves and S waves :)
What is the difference in arrival time between P and S waves equivalent to?
This value is related to the distance of the seismometer station from the earthquake's epicentre. The larger the difference in arrival times, the greater the distance.
Which of the following can cause damage days or month after a large earthquake?
the arrival of surface waves liquefaction a tsunami an aftershock
