The Richter scale is used to quantitatively measure the magnitude of an earthquake. This tool was devised by the seismologist Charles F. Richter in 1935. More » Science Earth Science Earthquakes

The Richter scale is used to determine the intensity of earthquakes, and a seismograph is a device that shakes with the ground during an earthquake. This movement is recorded by using ink to draw lines on paper that is c... More »

The Richter Scale measures the magnitude of an earthquake. The scale was created in 1935 by American seismologist and physicist Charles F. Richter. More »

A diagram that uses the Richter scale is used to measure the magnitude of an earthquake. When an earthquake takes place, a device called a seismograph records the earthquake's vibration, and multiple seismographs can for... More »

The difference between the Richter and Mercalli scales, both intended to measure earthquake severity, is that the Richter scale is a mathematical scale based on the measurements of scientific instruments, while the Merca... More »

The Richter scale does not have an upper limit. The Richter scale is a logarithmic representation of the amount of energy released by an earthquake, or its magnitude. As of 2014, the earthquake that rated highest in reco... More »

The Richter scale is logarithmic. Each whole-number jump indicates a tenfold increase in wave magnitude and a 31.7 increase in energy released. For example, a Richter 9 earthquake has 100 times the magnitude and 1004.89 ... More »
