A seismograph station is located 2000 km from an earthquakes epicenter Explain the order that the S and P waves will arrive at the station?

The P waves vibrate very quickly out from the epicenter first in all directions, in a circular way passing the station.
The S waves then vibrate out from the epicenter a few seconds later and cause the sideways shaking of the land as they pass the station.
The P wave then reflects off the core of the Earth and bounces back past the station, followed by the S wave a few seconds later because both waves reflect off the earths core back to the epicenter.

What is the difference of the P waves and S waves used to locate an earthquake's epicenter?
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.
What is the fewest number of seismograph stations that must record the arrival time of P and S waves in order for the epicenter of an earthquake to be located?
Three
Where is the focus located?
the focus is located under the epicenter. It is the origin of the earthquake. The epicenter is right above the focus.
Where in this diagram would an earthquake's epicenter be located?
Hello
What is located directly above the source of vibration on the earth?
Epicenter
How could u tell were the epicenter is located with 2 seismograph readings?
The difference between the two seismograph readings could tell you where the epicenter is located.
How many seismograph reading are needed before an earthquake's epicenter can be located?
three

What are the names of the earthquakes that happen in California?
The names come where the epicenter is located.
What is the fewest number of seismograph stations that must record the arrival time of P and S waves in order for the epicenter of an earthquake to be located?
Three
What is name of the unit which used to write earthquake?
An earthquakes magnitude is measures buy a Richter scale which was invented by Dr. Charles Richter in the 1930s a seismologist of the California state institution it is the measure of the largest seismic wave recorded on a certain seismograph located 100 clicks, roughly 62 miles from the epicenter of an earthquake.
How is the intensity and magnitude of an earthquake measured?
Earthquakes are measure with a seismograph which indicates the intensity of earth crust´s movements this measurement is call Richter 1 being less intensity and 10 being major intensity.
Where is the earthquake's epicenter is located?
The epicenter is the surface located right above the focus, which is the center of an earthquake.
Where is the focus located?
the focus is located under the epicenter. It is the origin of the earthquake. The epicenter is right above the focus.
Where does the epicenter located?
Its located above the focus
What type of of data do geologists use to locate an earthquake's epicenter?
I think you mean "Focus": the Epicentre is the point of maximum movement on the surface above, and that's usually obvious. The focus is located by triangulation and velocity calculations from seismograph data.
Is an earthquake's epicenter located deep underground?
False, the focus is located deep underground. The epicenter is at ground level
