Question

What is the difference between seismograph and Richter scale?

Answer 1

Hint:The concept of measuring something's "shaking" means that the term "seismograph" could be used in a broader sense. The Richter scale was designed to assess the magnitude of that "shaking".

Complete answer:
The difference between seismograph and Richter scale are:-

Seismograph	Richter scale
The seismograph, also known as a seismometer, is a device that monitors ground vibrations, including seismic waves generated by earthquakes, volcanic eruptions, and other seismic events.	The Richter scale assigns a number based on the amount of energy generated during the quake.
Seismologists use seismic wave recordings to map the interior of the Earth, as well as to find and measure the many origins of earthquakes.	The Richter scale is a base-10 logarithmic scale, which indicates that an earthquake with a magnitude of 5.0 has a shaking amplitude 10 times greater than one with a magnitude of 4.0, and corresponds to a 31.6 times greater energy release.
Negative magnitude quakes are now commonly recorded by many sensitive modern seismographs.	While the scale is commonly thought to be labelled from 1 to 10, with 0 serving as the baseline against which the energy is measured, the truth is that the scale has no lower limit.

Note:The Richter scale, it should be noted, cannot be used to quantify the total energy released by an earthquake or to characterise the amount of damage it caused. The Richter scale underestimates the energy released in earthquakes with magnitudes greater than 6.5 due to seismograph limitations and the emphasis on measuring a single peak amplitude, because the values calculated after measuring very large seismic waves tend to cluster, or "saturate," near one another.
