I believe that the machine is called a seismograph.
Seismographer
The Seismograph is used to measure the Magnitude of an earthquake.
An electroencephalogram (EEG) machine is commonly used to measure and record brain activity. EEG measures the electrical activity in the brain by placing electrodes on the scalp. This is a non-invasive method that helps in diagnosing various neurological disorders or monitoring brain function during research studies.
Used to measure earthquake activity with sound waves.
seismograph is generally used to measure earthquakes.
what machine can be used to measure sound waves
A seismometer (replacing the outdated term seismograph), but other instruments may also respond to an earthquake. The simplest example of a seismograph is a pendulum.
Earthquake measure
The Richter magnitude scale is used to measure the strength of an earthquake.
The Richter scale is a tool used to measure the energy released by an earthquake. It calculates the earthquake's magnitude based on the amplitude of seismic waves recorded on seismographs.
A seismic monitor is a device used to measure and record ground motion and seismic activity such as earthquakes. It typically consists of sensors that detect vibrations and convert them into electrical signals, which are then analyzed to provide valuable data about the occurrence and characteristics of seismic events.
An earthquake instrument is a device or tool used to measure and detect the different parameters associated with earthquakes, such as magnitude, intensity, and frequency. Some common earthquake instruments include seismometers, accelerometers, and tiltmeters, which help scientists monitor and study seismic activity.
