The distance between a seismic station and the earthquake epicenter is determined from the?
The difference in arrival times of P and S waves.
What will happen if there were only two seismic stations recorded waves from an earthquake?
Then you would end up with 2 possible locations for the epicenter. You need a 3rd station to confirm the actual location.
What types of waves are the first waves to reach seismograph stations?
P-waves are the first seismic waves to arrive at a seismograph station.
Is data about an earthquake from two seismographic stations enough information to locate the epicenter?
From Science Explorer Prentice Hall Earth Science: " Geologists use seismic waves to locate an earthquake's epicenter. Seismic waves travel at different speeds. P waves arrive at a seismograph first, with S waves following close behind. To tell how far the epicenter is from the seismograph, scientists measure the difference between the arrival time of the P waves and S waves. The farther away an earthquake is, the greater the time between arrival of the P waves and the S waves." Did this help?
When will the first p wave be received if an earthquake epicenter is approximately 1800 kilometers from the seismic station?
3.5 minutes after the earthquake.
What is the minimum number of seismograph station required to determine the location of an earthquake epicenter?
56
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.
One seismograph station by itself can determine the?
distance to the epicenter
How many seismograph-station readings are needed to pinpoint the epicenter of an earthquake?
Three
What is a seismograph station?
A seismograph station is a location containing equipment that can measure earthquake activity.
Can the SP time method be used with one seismograph station to locate the epicenter of an earthquake?
No. One seismograph station will only allow you to calculate the distance to the earthquake's focus. (The epicentre is on the surface above.) To find its exact location you need the recordings from at least 3 seismograph stations.For more information on the SP time method, please see the related question.
The distance between a seismic station and the earthquake epicenter is determined from the?
The difference in arrival times of P and S waves.
How is the fact that P waves travel more quickly the S waves used to determine the distance of an earthquake's epicenter from a seismograph station?
Given the difference in arrival times, you can determine the distance from the epicenter.
How is the distance between a seismic station and the earthquake epicenter is determined?
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.
How is the distance between the seismic station and the earthquake epicenter determined?
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.
Why is three the minimum of the stations necessary to locate an epicenter?
A single seismic station can tell you the distance to an earthquakes epicentre but will give you no information on it's location. Seismic vibrations take time to travel to a seismic station and when you have two seismic stations you can narrow down the location of the earthquake's epicentre to two possible locations. Add in a reading from a third station and you can nail down the exact location because if you draw 3 circles one round each station with the size of each circle proportional to the distance of the station form the epicenter, they will intersect at one location on the planet and that location is the epicenter.
If there are 3 records of the same earthquake how can the epicenter be determined?
The epicenter can be determined by measuring the time difference between the arrival of P and S waves, and then calculating the distance of the epicenter from each of the 3 stations. Once you have estimated the distance for each station you then draw a circle around each one. The place where the circles meet or intersect, is the epicenter.
