The machine leaves a pen tracing that indicates the magnitude of the earthquake
LOL
Use a Seismograph.
It is a seismograph
the ground shifts and there are tiny earthquakes.

No, the pen on a seismograph does not swing freely. The pen is stationery only until an earthquake occurs. Then the pen moves along the paper according to the way the ground is moving or quaking.

An eclipse happens when the moon moves between the earth and the sun.
The earth moves directly south in the earth
The Earth's surface will change its shape and form.
The part of the seismograph that moves during an earthquake is called the pen.
Seismometers are instruments that measure Earth's vibrations, also known as seismic waves. These devices can detect and record ground movement caused by natural events like earthquakes or human activities such as explosions.
Magnitude is how much the earth moved during an earthquake and is determined by the distance the marking device moves above and below the straight line on a seismograph.

A sudden movement of the Earth's crust is called an earthquake.
