What is the difference between a seismograph and a seismogram

Answer to: Are the seismograph and seismogram the same thing? By signing up, you'll get thousands of step-by-step solutions to your homework... Seismographs. Seismographs are instruments located at or near the surface of the Earth that record seismic waves. When the waves reach a seismograph, the seismograph creates a seismo- gram, such as the one in Figure 7. A seismogram is a tracing of earthquake motion created by a seismograph. When Did It Happen? Seismologists use seismograms to cal- We use exaggerated motion of a building (seismic station) to show how the ground moves during an earthquake, and why it is important to measure seismic waves using 3 components: vertical, N-S, and E-W. Before showing an actual distant earthquake, we break … What is a seismograph. A seismograph, or seismometer, is an instrument used to detect and record seismic waves. Seismic waves are propagating vibrations that carry energy from the source of an earthquake outward in all directions. They travel through the interior of the Earth and can be measured with sensitive detectors called seismographs. Seismogram is a graph output by a seismograph. It is a record of the ground motion at a measuring station as a function of time. Seismograms typically record motions in three cartesian axes (x, y, and z), with the z axis perpendicular to the Earth’s surface and the x- and y- axes parallel to the surface. A seismograph detects movement in the Earth's crust, translating that movement through its inner workings to move a recording device, often a needle, that makes markings on what becomes the seismogram. The base of a mechanical seismograph moves beneath the hanging needle, and on the base rests paper. On the paper rests the needle, which should not move when the ground beneath it … What is the difference between a sismogram and a seismograph? Seismograph is the intrument that records siesmic waves and the seismogram is what it produces that is a tracing of earthquake motion created by a seismograph: How many seismographs are needed to use the S-P-time method and why? When an earthquake caused the tin to vibrate, this seismograph was designed to release the ball from the dragon's mouth nearest to source of the quake. It was extremely effective, and even once alerted the local people of an earthquake occurrence that wasn't even felt. In the modern world, John Milne invented the first seismograph in 1880. This What does the position of the P-wave and S-wave on the seismogram tell you about each wave? Think about what you learned in lesson 2. ! 14. What is the difference in arrival time between the P-wave and S-wave. ! 15. Write a working definition of lag time (S-P interval). Unit 3 | Lesson 3: Reading a Seismogram… What is the difference between a seismograph and a seismogram? A seismorgraph records, and determines the strength of the Earthquake. A Seismogram is a tracing of the earthquake's motion created by the seismograph. Thus, the farther a seismograph station is from the epicenter, the greater the difference in the arrival times of the P and S waves. Suppose, for example, that a seismograph station in Berkeley, California, records an arrival-time difference of 1 minute 40seconds between the P waves and the S waves from a given earthquake. (See the seismogram

If a quake is far from the seismograph, the P-waves arrive long before the S-waves. The longer the time is between the P-and S-wave arrivals, the further away the earthquake was from the seismograph. First, seismologists calculate the arrival time difference. Then they know the distance to the epicenter from that seismograph. Technically speaking, a seismometer measures offset or motion, while an accelerometer measures proper acceleration. Seismometer outputs (seismographs) are generally in terms of displacement (meters) vs time, while accelerometer graphs will be in t... (2) the time interval between the arrival of the P-waves and S-waves (3) the difference in the direction of vibration of the P-waves and S-waves (4) the density of the subsurface bedrock through which the P-waves and S-waves travel 19. The seismogram below shows the arrival times of P- and S-waves from a single earthquake. As nouns the difference between seismograph and seismometer is that seismograph is an instrument that automatically detects and records the intensity, direction and duration of earthquakes and similar events while seismometer is (geology) a device used by seismologists to detect and measure seismic waves and therefore locate earthquakes etc; a seismograph. Far away, there will be more time between the two. By looking at the amount of time between the P and S wave on a seismogram recorded on a seismograph, scientists can tell how far away the earthquake was from that location. However, they can’t tell in what direction from the seismograph the earthquake was, only how far away it was.

The classical seismograph used beforethe coming of digital technology required the relative motioncause by earthquakes to be recorded by pen and ink on paper wrappedaround a rotating drum, or by a light spot on film, producingthe familar record known as a seismogram. 1. Scientists first determine the epicenter distance from three different seismographs. The longer the time between the arrival of the P-wave and S-wave, the farther away is the epicenter. So the difference in the P and S wave arrival times determines the distance between the epicenter and a seismometer. A seismogram is a record written by a seismograph in response to ground motions produced by an earthquake, explosion, or other ground-motion sources. An instrument used for recording the vibrations caused by earthquakes is known as seismograph or seismometer. The vibrations are recorded on a strip of paper and the diagram produced is known as a seismogram. Numerous models of seismographs are in current use. Most of these instruments have a high degree of precision and great sensitivity.

"A Seismogram is a written or digital record of an earthquake. In written form, it is a continuous line that shows vertical or horizontal Earth motions re-ceived at a seismic recording station and recorded by a Seismograph." Seismogram = is a tracing of the earthquake motion and is created by the seismograph. O seismogram is used to calculate when an earthquake began o seismogram is used to find the earthquakes epicenter o seismogram is used to find the earthquakes focus What is the difference between a seismograph and a seismogram? Epicenter = is the point. 7. Seismology is the study of earthquakes. Earthquakes are recorded on seismographs, and the record of an earthquake is a seismogram. 8. Describe how a seismograph works. 9. A seismogram is: a. An instrument that records earthquake waves; b. The record made by a seismograph; The distance of a seismic station from an earthquake is easily determined from the S-P interval, the time difference between the time of arrival of the first P wave and the first S wave. Triangulation: To determine the location of an earthquake the distance of the earthquake must be determined from at least three seismic recording stations. The difference in arrival times (in minutes) between the first P‐wave and first S‐wave for stations that are the following distances from an epicenter. 700 miles: _____ minutes difference 450 miles: _____ minutes difference 2500 miles: _____ minutes difference 2. From the seismogram The traces all begin and end at the same time, making it easy for the seismologist to see the difference in time between seismic events at several stations. Each station is part of the Canadian National Seismograph Network and has a unique identifier code of from 3 to 5 letters. For example, PNT is the station code for Penticton, BC. The seismograph's day begins at midnight, UTC time, which is 19:00 EST (7:00 p.M.). The helicorder records are near real-time. There is a 5 minute delay from the time the data are transmitted from the seismometer to the time they are displayed on the Internet. The delay is … 1.
