What is a seismogam?
the recording produced by a seismometer
How do you know a earthquake has ocurred?
Because they are recorded on a seismometer.
What is an instrument used to detect and record earthquakes?
There are two instruments, which are basically the same thing. There is the seismograph , and a more specific tool measures the waves on what is called the Richter scale. Earthquakes are given a number from one to ten, ten being the strongest. The strongest earthquake that their ever was, was measured a 9.3.
What name is given to the instrument used to measure earthquakes?
A seismometer.
When a scientist designs a probe to detect life on a distant planet what kind of things should it measure?
things like contents of atmosphere, heat, etc.
How r earthquakes recorded?
An earthquake is recorded by a measurement called Richer scale and Mercille scale or the Seismometer. A seismometer is an instrument . . . While not sensitive enough to detect it.
How do you detect the magnitude of an earthquake?
You use a seismometer. Then, measure the magnitude according to the Richter scale.
Which type of wave does a seisemeter detect first?
A seismometer detects primary waves (P-waves) first. These are the fastest seismic waves and are the first to arrive at a seismometer after an earthquake.
An instrument used to detect and record earthquakes?
A seismometer is used to detect and record earthquakes by measuring the motion of the ground. It consists of a mass suspended on a spring that moves with the vibrations caused by an earthquake, which is then recorded on a seismograph.
What do you call an instrument used to detect and record earthquakes?
Seismometer (or seismograph) and it measure seismic waves
When was Seismometer created?
Seismometer was created in 1880.
What instrument is used to detect vibrations in an earthquake?
Seismometers. For information on how seismometers are used, please see the related question.
Why are 3 seismometers required to locate exactly where an eartquake occurred?
The seismometer records the P and S-wave arrival times. P-waves travel faster through the earth than S-waves and so they arrive at the seismometer station before the S-waves and are recorded by the seismometer first. The difference in arrival time between the two types of seismic wave can be used to calculate the distance of the earthquake's epicentre from the seismometer. This can then be plotted on a map, by drawing a circle with a radius equal to the distance to the epicentre around the seismometer station. This is then repeated for the other two seismometer stations and the point where the three circles intersect is the location of the earthquakes epicentre.
What tool is used to measure an earthquake?
Scientists use a recording instrument called a seismograph to detect ground motions caused by seismic waves from earthquakes.
What instrument are used to warn us about a pending earthquake?
A seismometer, or seismograph. One of the two! :)
What is the homophone for detect things with your eyes?
my head
What machine detects earthquakes?
A seismometer (the term seismograph may be used to describe a seismometer combined with an instrument for recording and displaying the amplitude and frequency of the seismic waves that the seismometer measures). Please see the related link.
