Ground motion, earthquakes and nuclear explosions for example.
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.

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.
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.
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.
Seismometer (or seismograph) and it measure seismic waves
A seismometer station is a facility equipped with seismometers, instruments that detect and record ground motion from seismic waves generated by earthquakes or other sources. These stations are strategically located worldwide to monitor and study seismic activity. The data collected from seismometer stations help scientists assess earthquake hazards and understand the Earth's internal structure.
Seismometer was created in 1880.
A seismometer is typically larger than a manometer. Seismometers are designed to detect and measure seismic waves, which requires more complex components and sensors. Manometers, on the other hand, are used to measure pressure and are generally smaller and simpler in design.

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.
A seismometer, or seismograph. One of the two! :)
