What is seismograph in an earthquake?
There are two instruments, which are basically the same thing. There is the seismograph , and a more specific tool measures the waves on what is called the Richter scale. Earthquakes are given a number from one to ten, ten being the strongest. The strongest earthquake that their ever was, was measured a 9.3.

How do you use circles to find the epicenter of an earthquake?
Scientists can calculate the distance that an earthquake occurs from a seismometer station by looking at the record of the seismic waves and measuring the difference in time between the arrival of P and S-waves. This gives them a distance but not a direction. So they plot this distance on a map by drawing a circle round the seismometer station. The radius of this circle is equal to the distance to the epicentre. If this is done for one other seismometer station that has recorded the earthquake then the circles will intersect in two places. If you add in a 3rd station and so a third circle they will all intersect in one place - the epicentre of the earthquake. In reality this process is automated by computer and lots of readings from lots of stations are used.
What is used to record the shaking of an earthquake?
A Seismograph is an instrument designed to record earthquake shocks mechanically. Seismology is the study of earthquakes, one proficient in this science is called a seimologist-= like Dr. Richter of scale fame. among the various manufacturers of Seismographs is the Sperry Company, better known for Gyroscopes, gyro-compasses and the like. I believe both the Fordham and Oberlin seismological observation stations use Sperry instruments. Shake, Rattle, and Roll- Three axis models.
What tool do scientists use to predict earthquakes?
Five instruments that may be used in an attempt to predict an earthquake are the following:1. Creepmeter, which straddles the fault line and shows when the soil above the earth's crust starts to move as part of an earthquake;2. Global positioning system, which shows when the earth's crust starts to shift as part of an earthquake;3. Laser light, which straddles the fault line and shows when a light beam from one side isn't transmitted in the expected amount of time or to the expected place on the other;4. Magnetometer, which shows the changes that are made to the magnetic field by the underground activities leading to an earthquake;5. Strain meters, through the coordinated use of the seismograph and seismometer, to show the presence of the vibrations that lead up to and are part of an earthquake.
Can s-p time method be used with one seismograph station to locate the epicenter of and earthquake?
No, the S-P time method requires data from at least three seismograph stations to triangulate the epicenter of an earthquake. With only one station, it is not possible to accurately determine the epicenter.
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.
What is the smallest number of seismographs needed to determine the distance of an earthquake form a particular seismic station?
To determine the distance of an earthquake from a particular seismic station, a minimum of one seismograph is needed. However, to accurately locate the earthquake's epicenter, at least three seismographs are required. This is because the intersection of the distance circles from each seismograph allows for a precise determination of the earthquake's location.
One seismograph station by itself can determine the?
One seismograph station by itself can determine the approximate location of an earthquake, as well as provide information on the earthquake's magnitude and timing. However, having multiple seismograph stations in different locations allows for more accurate determination of the earthquake's epicenter and depth.
Is there a machine that locates earthquakes?
seismograph However one only shows how far away the earthquake was, to locate the earthquake you need several in different locations and have to perform triangulation based on the different measurements.
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 an instrument used to measure and record ground movements during an earthquake?
A seismometer is an instrument used to measure and record ground movements during an earthquake. It detects the vibrations caused by seismic waves and produces a graphical representation called a seismogram.
What does data from one seismograph tell you when an earthquake occurs?
How far away the epicenter is.
What can you learn from only one seismogram?
From one seismogram, you can learn about the timing, magnitude, and location of an earthquake. By analyzing the wave patterns captured on the seismogram, seismologists can determine the earthquake's Richter magnitude, depth, and distance from the seismograph station that recorded it.
What machine measures the strength of the energy waves sent out from an earthquake?
A seismograph is the machine that measures the strength of energy waves, such as seismic waves, generated by earthquakes. The data recorded on the seismograph is used to determine the earthquake's magnitude.
