How does a seismograph work quizlet?
A seismograph works by suspending a weight from bedrock, which remains motionless during an earthquake. A rotating drum that is affixed to the moving bedrock moves as the rock moves, recording the relative displacement between the stationary weight and the rotating drum.
How is the seismograph used today?
A modern seismograph can help scientists detect earthquakes and measure several aspects of the event: The time at which the earthquake occurred. The epicenter, which is the location on the surface of the earth below which the earthquake occurred. The depth below the earth’s surface at which the earthquake occurred.
Seismographs are instruments located at or near the surface of the earth that records seismic waves. A seismogram is a tracing of earthquake motion and is created by a seismograph.
What is a seismograph What is the underlying principle of seismograph construction?
The underlying principle of seismograph construction is to have a heavy weight suspended from a spring over a base or within a moving box.

SELECT ALL THAT APPLY. A seismograph works by suspending a weight from bedrock, which remains motionless during an earthquake. A rotating drum that is affixed to the moving bedrock moves as the rock moves, recording the relative displacement between the stationary weight and the rotating drum.
What part of the seismograph remains motionless?
What doesn’t move, however, is a suspended mass inside the seismograph, called the seismometer. During an earthquake, the seismometer remains still while the case around it moves with the ground shaking. Traditionally, the suspended mass was a pendulum, but most modern seismometers work electromagnetically.
What is an example of a seismograph?
Frequency: The definition of a seismograph is a measuring instrument for earthquakes that tracks duration and magnitude. A device used to measure the duration and magnitude of a San Francisco earthquake is an example of a seismograph.
How are seismographs used?
Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic network.
What does a seismograph record?
A seismograph is a scientific instrument which records information about the duration, intensity, and direction of a seismic disturbance, classically an earthquake. In addition to registering earthquakes, seismographs can also track large explosions, tidal waves, and other events which cause the ground to shake.
What is an earthquake seismograph?
Seismograph, instrument that makes a record of seismic waves caused by an earthquake, explosion, or other Earth -shaking phenomenon. Seismographs are equipped with electromagnetic sensors that translate ground motions into electrical changes, which are processed and recorded by the instruments’ analog or digital circuits.
