What remains in a fixed position in a seismograph during an earthquake?

What remains in a fixed position in a seismograph during an earthquake?

A seismograph, or seismometer, is an instrument used to detect and record earthquakes. Generally, it consists of a mass attached to a fixed base. During an earthquake, the base moves and the mass does not. The motion of the base with respect to the mass is commonly transformed into an electrical voltage.

How does a seismograph measure an earthquake?

A seismograph is the primary earthquake measuring instrument. The seismograph produces a digital graphic recording of the ground motion caused by the seismic waves. The digital recording is called a seismogram. A network of worldwide seismographs detects and measures the strength and duration of the earthquake’s waves.

How can a seismograph measure ground shaking if all parts of it must be attached to the ground?

How can a seismograph measure ground shaking if all parts of it must be attached to the ground? They use a large mass combined with levers and electronicsro magnify the signal, making very small signals detectable.

What is stationary during an earthquake?

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 remains in a fixed position in a seismograph during an earthquake quizlet?

-A seismograph works by suspending a weight from bedrock, which remains motionless during an earthquake.

How do we monitor earthquakes?

Seismic monitoring utilizes sensitive seismographs to record the ground motion from seismic waves created by earthquakes or other sources. Seismograms from seismic monitoring stations can be used to determine the location, origin time, and magnitude (as well as other characteristics) of earthquakes.

How does a seismograph work ks2?

When an earthquake hits, it sends out seismic waves, which are waves that travel through the ground, causing the earth to shake. Scientists can measure and record the seismic waves made by an earthquake using an instrument called a seismograph. An earthquake’s strength is recorded using the Richter scale.

What does a seismograph record quizlet?

A seismograph is an instrument that records and measures the details of an earthquake.

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.
