AThere are a number of different types of seismometers and they all work in slightly differing ways but generally are based around the same principle.
That principle is inertia. Inertia basically means that stationary masses will remain stationary until a force is applied to them. Conceptually a seismometer can be thought of as a weight or mass, suspended by springs in a frame which is bolted to the floor.
When an earthquake occurs the frame which is attached directly to the floor is caused to move by the seismic waves, however the mass / weight on the spring does not as the seismic waves do not directly affect it (their effect is dampened by the inertia of the mass and the springs). If you were to attach a pencil or pen to the weight and a piece of graph paper to the frame so that they were touching the movement of the frame relative to the stationary mass would be recorded.
Modern seismometers are much more complex than this but in essence rely on this principle.

∙ 13y agoA seismogram is what measures the size of a woman's breasts. This is usually used before a mammogram.
This is the most ridiculous answer that i have ever heard. It is similar to a seismograph and its main function is to measure seismic waves, so scientists can determine the magnitude of an earthquake.

∙ 10y agoA seismometer works by sticking a long pipe into the ground. The pipe has motion detectors attached to it, so when there is an earthquake its severity is decided based on how much the pipe moves.

How many seismometers do you need at a given place to fully record the motions arising from earthquake waves?
You need a seismometer for each axis of motion. As such it takes three seismometers.
What is the instrument that detects measures and records the energy of earthquackes vibrations called?
It's called Seismometers
How does a seismometer work and what does it measure?
There are a number of different types of seismometers and they all work in slightly differing ways but generally are based around the same principle. That principle is inertia. Inertia basically means that stationary masses will remain stationary until a force is applied to them. Conceptually a seismometer can be thought of as a weight or mass, suspended by springs in a frame which is bolted to the floor.

Modern seismometers are much more complex than this but in essence rely on this principle. As such seismometers measure the frequency and amplitude of the movements of ground surface as caused by seismic waves.
What is the difference between a seismograph and a seismogram?
Most of vibrations can be detected and recorded by sensitive instruments called seismograph, or seismometers. The record produced by a seismometer is called a seismogram.
What predictions can be made using evidence gathered by seismometers?
almost none... ever. no predictions can be made from a single recording because earthquakes are too random
How do they use seismometers to locate the origin of the earthquake?
You can think of this in the same way that satellites work to find your location for the GPS in your car. An earthquake happens and it is picked up on 3+ seismometers. These seismometers measure the waves that the earthquake produced and the velocity at which they are traveling and you look at where all the seismometer calculations run together. You have the epicenter of your earthquake.
What instrument detects seismic waves?
A seismograph is one such instrument...there might be others.
What has the author Samuel D Stearns written?
Samuel D Stearns has written: 'Applications of the coherence function in comparing seismometers' -- subject(s): Seismometers
What instrument is used to detect vibrations in an earthquake?
Seismometers. For information on how seismometers are used, please see the related question.
How do you know earthquakes happened?
Because they are detected by seismometers.
How many seismometers do you need to record an earthquake?
3
What are ways the scientists can learn about the earths mantle?
seismometers
How many seismometers do you need at a given place to fully record the motions arising from earthquake waves?
You need a seismometer for each axis of motion. As such it takes three seismometers.
Has anyone had a consistent successful way to predict earthquakes?
Seismometers work pretty well for measuring them. But there is no true way to predict an earthquake. All methods have not been proven successful
What type of technology is used to predict earthquakes and volcanos?
seismometers and seismographs
What are the tracings of a seismometers called?
The trace produced by a seismograph is called a seismogram.
What frequency does seismometers uses?
Seismometers are interested in the vibrations of the Earth, for different reasons. Some may be interested in the geological process. Some in the response of buildings and other structures. Seismometers can respond to very low frequencies, down towards 1 milli-Hertz. And up to a few hundred Hertz. These machines do not 'use' frequencies, they merely record what is naturally happening.
