^{MainMainRichter scale, widely used quantitative measure of an earthquake’s magnitude (size), devised in 1935 by American seismologists Charles F. Richter and Beno Gutenberg. Magnitude is determined using the logarithm of the amplitude (height) of the largest seismic wave calibrated to a scale by a seismograph.The intensity of earthquakes is measured on the Richter scale. It is a device which compares earthquakes. Whenever an earthquake comes, we can measure the ...This means that an earthquake of 6 is ten times more powerful than one with a score of 5 and an earthquake of 7 is 100 times more powerful than an earthquake measuring 5 on the Richter Scale. …A 4.7 magnitude earthquake was measured about 30 miles south of Eureka, California early on Monday morning, according to the National Weather Service Eureka station.Caltech's Charles Richter conceptualized magnitude. He developed a method to numerically report the relative sizes of earthquakes before earthquake magnitude could be measured directly. He described the first magnitude scale, which came to be known as the Richter scale, in a paper published in 1935. What is intensity? The magnitude of an earthquake is measured by a machine called a seismometer. A seismometer produces a seismograph.

A seismogram is a record of the ground motions caused by seismic waves from an earthquake. A seismograph or seismometer is the measuring instrument that creates the seismogram. Almost all seismometers are based on the principle of inertia, that is, where a suspended mass tends to remain still when the ground moves. Most earthquakes occur along the boundaries between the Earth’s tectonic plates. The crust of the Earth is divided into plates. When a plate collides with or slides past another plate, this causes earthquakes.Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept.
