Why three seismograph stations are needed to determine the location of an epicenter?
Three seismograph stations are needed to determine the location of an epicenter because each seismograph can determine distance to the epicenter but not direction. The point where the three circles intersect is the epicenter of the earthquake. +++ Focus - not epicentre, which is the point of maximum movement on the surface above the slip itself.
What is the method used to figure out the epicenter of an earthquake?
epicenter and seiesmic waves, find the distance and seismograph stations
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.
Which gas is most effective in absorbing outgoing radiation emitted by earth?
how can you determine the maximum distance in kilometers (km) that tsunami waves (shown as series of concentric curved dashes) travelled from the epicenter.
What can you figure out about an earthquake from only one seismic station?
the distance to the epicenter
One seismograph station by itself can determine the?
distance to the epicenter

Geologists use the difference in the arrival times of P waves and S waves at a seismograph to determine?
The distance to the epicenter

epicenter and seiesmic waves, find the distance and seismograph stations
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.
What is the relationship between lag time and distance from an earthquake's epicenter?
The more is the time taken and the distance recorded by the seismograph, the more is the effect of an earthquake:)
Can the s-p time method be used with one seismograph station to locate the epicenter of an earthquake?
The first step in this method is to collect several seismograms of the same earthquake from different locations. Then, the seismograms are placed on a time-distance graph. The seismogram tracing of the first P wave is lined up with the P-wave time-distance curve, and the tracing of the first S wave is lined up with the S-wave curve.The distance of each station from the earthquake can be found by reading the horizontal axis. After finding out the distances, a seismologist can locate an earthquake's epicenter.-New Boyz
What is a seismic travel time curve?
A seismic travel time curve describes the relation between the travel time of a seismic wave and the epicentral distance. It is used to calculate the calculate the distance of the earthquake's epicenter from the seismograph.
How can geologists tell where the epicenter of an earthquake is?
The epicenter refers to the point on the earth's surface above the focus of an earthquake. Geologists determine the epicenter with the use of 3 seismographs. This method is called triangulation.
What type of data do geologists use to locate earthquakes epicenter?
Seismologists use the data from triangulated seismographs to locate an earthquake's epicenter. The difference in time between the arrival of p and s waves at a seismometer tells the distance to the epicenter of an earthquake. To get the exact location, scientists must collect data from at least three seismometers. The point where all three circles is the epicenter of the earthquake. +++ The Epicentre is generally obvious: it is the point of maximum disturbance on the surface. The centre of the actual slip is the Focus, and this has to be calculated from seismograph data by triangulating from wave velocities.
The distance between an earthquake epicenter and the location of a seismograph can be calculated because?
4. shear waves and compression waves travel at different speeds, therefore the difference in arrival time can be used to fix the distance.
