Ground motion, earthquakes and nuclear explosions for example.
seismographs tell you how strong the earth quake was and helps you find the epicenter of the quake.
A seismograph shows where the earthquake began, as well as how long it lasted and the amount of energy released.
the recording produced by a seismometer
Because they are recorded on a seismometer.
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.
A seismometer.
things like contents of atmosphere, heat, etc.
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.
You use a seismometer. Then, measure the magnitude according to the Richter scale.
seismic waves
Seismometer (or seismograph) and it measure seismic waves
Seismometer was created in 1880.
Seismometers. For information on how seismometers are used, please see the related question.
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.
Scientists use a recording instrument called a seismograph to detect ground motions caused by seismic waves from earthquakes.
A seismometer, or seismograph. One of the two! :)
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.
Yes, that is one of the things they are taught to detect.
The seismometer measures how bad and earthquake is and a Richter Scale measures hoe bad a hurricane is.
