iT MEASURES EARTHQUAKE TREMORS AND SHOCKS- Some can also be used- a two-truck team for these portable ones- for prospecting for underground oil and gas deposits. one truck shoots off ( through a well or derrick framework) an underground depth charge, the other truck- they are in touch by two way radio but use whistle blast signals- records the shockwaves on a modified seismograph, analysis of the seismogram or chart can be used to deduce if there are any echo anomalies caused by Oil or natural gas deposits. Generally, the term is used for instruments measuring and recordind earthquake shocks on the Richter scale. 7.0 is a big Jolt- but the Japanese Quake that caused the nuclear accident- went up to 9.0 Great Quake.

∙ 10y agoA seismogram is the graph produced by a seismograph. The purpose of a seismogram is to record, or reveal, the location and severity of an earthquake. A seismogram can also reveal how far a seismic wave occurred from the actual seismograph.

Where are most seismographs located?
seismometers are put within the two small surface stations.æ ╬_╬
What are the tracings of a seismometers called?
The trace produced by a seismograph is called a seismogram.
What intruments scientist use for earthquakes?
Earthquakes are detected and measured using seismometers or seismographs.
seismometers?
instrument that respond to ground motions such as caused by earthquakes, volcanic eruptions and explosions
What is the most common tool used to measure earthquake?
The instruments are seismographs or seismometers.

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.
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.
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 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.
