It's called Seismometers
A seismometer or seismograph
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.
A seismograph measures and records the waves generated by earthquakes and similar seismic events.Earlier devices had separate measuring (seismometer) and recording instruments.
A magnetometer is a device that is used to detect magnetic fields on the seafloor. It was invented by Sheldon Breiner.
seismometer
A seismometer detects the earthquake vibrations that the seismograph records.
a Seismograph measure earthquake vibrations
It detects ground vibrations.
Vibrations and their giant ears.

Lateral Line
The lateral line of a fish detects vibrations in the water and transmits them to the brain. The external ear in humans detects vibrations in air, water, and solids and transmits them to the brain.
Seismometer
It is a sensor that measures/ detects oxides of nitrogen.
The instrument types are known collectively as seismometers and seismographs. A seismometer detects the vibrations that travel through the ground, and a seismograph makes a visual record of the amplitude of waves over a period of time.
