What is a Richter scale used for?
The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs.
Who invented Richter scale?
Charles Francis RichterRichter scale / InventorCharles Francis Richter was an American seismologist and physicist.
Richter is most famous as the creator of the Richter magnitude scale, which, until the development of the moment magnitude scale in 1979, quantified the size of earthquakes. Wikipedia
What is the difference between Richter and Mercalli?
While the Mercalli scale describes the intensity of an earthquake based on its observed effects, the Richter scale describes the earthquake’s magnitude by measuring the seismic waves that cause the earthquake. The two scales have different applications and measurement techniques.
What is a disadvantage of using a Richter scale?
Disadvantages of Richter Scale Earthquakes can cause subsidence, or the lowering of the ground surface. This can cause coastal areas to be permanently flooded. Lateral spreading can also occur, wherein sloping ground moves downhill, opening up cracks.
How Richter scale is calculated?
Richter scale (ML), quantitative measure of an earthquake’s magnitude (size), devised in 1935 by American seismologists Charles F. Richter and Beno Gutenberg. The earthquake’s magnitude is determined using the logarithm of the amplitude (height) of the largest seismic wave calibrated to a scale by a seismograph.
What is the Richter scale range?
0 to 9
Numbers for the Richter scale range from 0 to 9, though no real upper limit exists. An earthquake whose magnitude is greater than 4.5 on this scale can cause damage to buildings and other structures; severe earthquakes have magnitudes greater than 7.
Why is it called the Richter scale?
The Richter scale – also called the Richter magnitude scale and Richter’s magnitude scale – is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the “magnitude scale”.
What is the range of Richter scale?
Although the Richter Scale has no upper limit, the largest known shocks have had magnitudes in the 8.8 to 8.9 range. Recently, another scale called the moment magnitude scale has been devised for more precise study of great earthquakes. The Richter Scale is not used to express damage.
What is the highest Richter scale?
Although the Richter Scale has no upper limit, the largest known shocks have had magnitudes in the 8.8 to 8.9 range. Recently, another scale called the moment magnitude scale has been devised for more precise study of great earthquakes.
What is the difference between seismograph and Richter scale?
A seismograph is an instrument used to detect and record earthquakes. It is also known as a seismometer. It records the motion of the ground during a quake. The Richter scale is a numerical value used to measure the power or magnitude of earthquakes.
Why is it called Richter scale?

Which country has the largest 20 Cent earthquake?
Chile earthquake of 1960, the largest earthquake recorded in the 20th century. Originating off the coast of southern Chile on May 22, 1960, the temblor caused substantial damage and loss of life both in that country and—as a result of the tsunamis that it generated—in distant Pacific coastal areas.
