This was based on a 1928 work by the Japanese seismologist Kiyoo Wadati, who had represented the oscillations in relation to the distance to the epicentre (the point of the surface directly above the focus of the earthquake). Richter thought of using the amplitude values of seismic movements recorded by the seismograph pen on paper. It was useful as a crude approach, but subjective and of little scientific value. It results in a 100 percent increase in the shaking of the Earth and a release of 3.1 times more energy than the 7.1 magnitude earthquake.In the 1930s, American seismologist Charles Francis Richter (26 April 1900 – 30 September 1985) of the California Institute of Technology (Caltech) set out to solve an unsettled question in the study of earthquakes-how to compare them according to a standardized method? The Mercalli intensity scale, used at that time, was governed by the levels of destruction observed after an earthquake. In a 7.2 magnitude earthquake, the amplitude of the wave is 100 percent more than a 7.1 magnitude earthquake.The difference between a 7.1 magnitude earthquake and a 7.2 magnitude earthquake means that on the Richter scale or Moment Magnitude scale the difference amounts to a 0.1 magnitude.The 7.1 and 7.2 magnitude earthquakes have different amplitudes of waves, and they cause different amounts of shaking of the Earth’s crust as well as different amounts of damage.A 7.1 or 7.2 magnitude earthquake refers to the different measurements of earthquakes being observed or measured on the Richter scale or Moment Magnitude scale.The energy released by 7.2 magnitude earthquakes can cause far more damage than the earthquake measuring 7.1 on the Richter or Moment Magnitude scale and can cause far more shaking of the Earth’s crust. It results in a 100 percent increase in the shaking of the Earth and a release of 3.1 times more energy than the 7.1 magnitude. A 0.1 magnitude is something worth noticing as the damage caused by the amplitude of the wave is 100 percent more. The difference between a 7.1 magnitude of an earthquake and a 7.2 magnitude of an earthquake means that on the Richter scale or on the Moment Magnitude scale the difference amounts to 0.1 magnitude. An earthquake magnitude is basically measured on a scale of base-10. The magnitude of an earthquake is calculated by a logarithm of different waves and their amplitudes by the seismograph. The main difference between a 7.1 and a 7.2 earthquake is the magnitude of the earthquake. The energy released dissipates into the crust of the Earth and dissipates through other subsurface structures. The energy released by earthquakes is not transmitted through the Earth’s surface. The earthquakes more than a magnitude 7 are considered dangerous and may cause serious damage to a large area. If they are less than 5, then they are measured on local scale called the Richter scale. If the earthquake magnitude is larger than 5, then it is observed as a moment magnitude. Different magnitudes of earthquakes are measured by different scales. They are measured by seismometers and have different magnitudes. Seismic activity or the seismicity of a place refers to the type, size, and frequency of a particular earthquake. Earthquakes can be caused by natural activities like landslides, volcanic activities, etc., as well as human activities like nuclear tests, mine blasts, etc. When the Earth’s crust suddenly releases energy and creates seismic waves, it is called an earthquake. They are also called a temblor or tremor or quake.
