The Richter scale rates the amount of energy released from a single earthquake, letting us know the magnitude of the disaster. A seismograph is what scientists use to actually measure the earthquake and the Richter scale is a way of putting the data into an understandable context.

Difference between Seismograph and Richter scale

Seismograph

The seismograph is an instrument that measures the movements of the earth, i.e. seismic waves generated by earthquakes, volcanic eruptions and other sources. Seismic wave records help seismologists map the interior of the earth, locate and measure the different sources of earthquakes.

The first seismograph was designed by Zhang Heng of the Han Dynasty of China in AD 132. It was called “Houfeng Didong Yi,” which literally means “an instrument for measuring seasonal winds and earth movements.”

Zhang Heng’s original plans for the seismometer (as it is also called the seismograph) were lost over time. However, historians and scientists were able to retrieve enough information to be able to create a model. After 1880, most seismometers were descended from those developed by John Milne’s team, James Alfred Ewing and Thomas Gray, who worked in Japan from 1880 to 1895. After World War II, these seismometers were adapted again.

This instrument has a weight hung from a spring, so it is sensitive to the movements of the earth. Changes in movement recorded by this device can help indicate the likelihood of an earthquake. S however, this creates another problem How to properly describe the intensity of the earthquake once it occurs?

RICHTER SCALE

This scale is the one used to measure the intensity of earthquakes. Thus depending on how intense these are assigned a number ranging from 1 to 10, where 1 is very low intensity and 10 is very high.

It was developed by Charles Francis Richter in collaboration with Beno Gutenberg in 1935. Or riginally it was to be used only in a study area located in California, however, eventually the scale was converted into an accepted norm worldwide.

The Richter scale assigns a number based on how much energy is released during the earthquake. E is a base 10 logarithmic scale, which means that an earthquake measuring 5.0 on the Richter scale has an intensity 10 times greater than one that measures 4.0.
