Volcanic Explosivity Index
Geologists use the moment magnitude scale (Mw) to rate the magnitude of an earthquake today. This scale takes into account the seismic moment, which provides a more precise measurement of an earthquake's size compared to the Richter scale.
Scientists most often use the Richter scale or the moment magnitude scale to express the magnitude of an earthquake. These scales measure the energy released by an earthquake and provide a numerical value to indicate its intensity.
Scientists use seismographs to measure the magnitude of earthquakes. Seismographs detect the seismic waves generated by an earthquake, and the amplitude of these waves is used to calculate the earthquake's size. The most common scale used to measure earthquake size is the Richter scale or the moment magnitude scale.
Seismologists use the Richter scale or the moment magnitude scale to measure the tectonic activity of earthquakes. These scales provide a numerical value that represents the size or magnitude of an earthquake based on the seismic waves recorded by seismographs.
Scientists normally use something called the Richter scale to measure earthquakes. They measure in maginitude. 1 on the Richter scale would be small vibrations through the earthquake zone where as 10 would be total destruction. Hope that's helped!
A force meter or spring balance can measure force magnitude.
Since a seismograph is a device used to measure the magnitude earthquakes, someone who studies earthquakes would use it.
The apparent magnitude of a star is a measure of its brightness.
seismograph is one instrument that could measure earthquakes and volcanoes etc but seismograph is many times use at earthquake!
You use a seismometer. Then, measure the magnitude according to the Richter scale.

They use a richter scale to measure intensity and magnitude.
A spectrometer would be commonly used to measure the amount of sulfur dioxide emitted by a volcano. This instrument can detect and quantify the concentration of sulfur dioxide in volcanic plumes by analyzing the absorption of light at specific wavelengths.
A commonly used instrument to measure sulfur dioxide emission from a volcano is a UV spectrometer. This instrument can detect and quantify sulfur dioxide by measuring the absorption of ultraviolet light at specific wavelengths. Other methods, such as Fourier-transform infrared spectroscopy, can also be used for this purpose.
The most commonly referred to scale by the press and the public is the Richter scale for measuring earthquake magnitude. However this was actually replaced in the 1970s by the Moment Magnitude scale which is the magnitude scale favoured and in use by seismologists.

Astronomers use apparent magnitude to measure the brightness of celestial objects as seen from Earth. The apparent magnitude scale is logarithmic, with smaller numbers representing brighter objects and larger numbers representing dimmer objects.
