Two separate systems used to measure earthquakes are important for accuracy. More than one system to measure gives scientists an accurate measurement of an earthquakes strength.
because of moving of tectonic plates
Earthquakes don't really have a purpose; they just happen. "Purpose" implies that the said process can be useful. Rain also occurs naturally, but we use it to cultivate fruits and vegetables. You could say that is its "purpose." Earthquakes, on the other hand, aren't useful to us at all. They can cause massive damage and the kinetic energy involved cannot be harnessed.
Cogeneration, or combined heat and power (CHP), is the production of electricity and useful thermal energy (such as heat or steam) from the same fuel source in a single process. This process increases the overall efficiency of energy production compared to separate generation methods.
Yes, soil can be separated through physical processes such as sifting or sieving to separate out different particle sizes. This can be useful for analyzing soil composition or for preparing soil samples for specific experiments or studies.
Earthquake simulators are useful tools because they allow scientists and engineers to study the effects of earthquakes on structures without having to wait for a real earthquake to occur. This can help in designing and constructing buildings that are better able to withstand seismic activity. Additionally, earthquake simulators can be used to test the effectiveness of different earthquake-resistant technologies and building materials.
They're not.
Whenever the data covers a very large range of values a log scale if very useful. Earthquakes and hearing are common examples.

APR is the most useful measure of interest rate.
As a basis of comparison to a known standard. This helps in better understanding the nature of earthquakes over a long period of time.

A seismograph as important today because it can monitor movement of the ground before an earthquake happens and it can inform people. That way you can send help fast and save many peoples lives.

They generate electricity......
Earthquakes are useful in studying plate boundaries because they often occur along these boundaries when tectonic plates interact. The distribution and frequency of earthquakes help scientists map the boundaries and understand the movement of the plates. Monitoring earthquakes can also provide valuable insight into potential hazards in regions prone to seismic activity.
Richter scales are useful to measure only small, shallow earthquakes recorded within a certain distance from the epicenter. A moment magnitude scale is more precise than a Richter scale. It also gives a measure of the energy released during an earthquake.
