To try to predict earthquakes, and get advanced warning of them.
Semogram
A seismograph is an instrument that produces a record of seismic waves by detecting and measuring the vibrations caused by earthquakes or other seismic events. It consists of a seismometer to detect ground motion and a recording device to produce a trace of the detected seismic waves.
Seismographs do not record air movements caused by seismic waves. Seismographs specifically detect and record ground movements, such as vibrations or oscillations in the Earth's crust, produced by seismic waves generated by earthquakes or other sources. The air movements caused by seismic waves do not directly influence the seismograph readings.
A seismometer or seismograph is a device used to record seismic waves generated by earthquakes or other sources. It detects and measures the vibrations caused by these waves, providing valuable data for studying the Earth's interior and understanding seismic activity.
this is where the seismic waves recorded; measures vertical earth motion

Scientists use an insrument with the name of a seismograph
Seismic waves are measured using seismometers, which detect the ground vibrations created by seismic events like earthquakes. Seismometers record the data in the form of seismograms, which show the amplitude and arrival times of different types of seismic waves such as P-waves and S-waves. By analyzing these seismograms, scientists can determine the characteristics of the seismic event and its location.
Seismic waves are any waves that travel through the Earth. As such all earthquake waves are seismic waves, however not all seismic waves are caused by earthquakes.
On the drum of a seismic recorder, the pen moves up or down according to the earthquake waves reaching it, giving a 2D record.
(not seismic, seismic wave)Seismic waves are waves of energy that travel through the earth.
