Scale used to measure the magnitude of an earthquake.
The Richter Scale measures earthquakes by using seven different categories: micro, minor, light, moderate, strong, major, and great. Below is a look at each description: Micro earthquakes are measured at between 1 and 1.9. This magnitude would be considered a I on the Mercalli intensity scale. These earthquakes are not noticed by …
Another issue with Richter was that the scale was calculated from one type of earthquake wave, a kind that doesn't help much when measuring truly massive quakes, like Japan's magnitude-9 in 2011.The moment magnitude scale (Mw) is a logarithmic scale used to measure the size of earthquakes. It is based on the seismic moment, which is a measure of the energy released by an earthquake.

The Richter scale is a tool used to measure the magnitude of earthquakes. Developed in the 1930s by seismologist Charles Richter, …mb = log ( A / T) + Q ( D, h ) where A is the ground motion (in microns), T is the wave's period (in seconds), and Q ( D, h) is a correction factor that depends on distance to the quake's epicenter D (in degrees) and focal depth h (in kilometers). Surface-wave magnitude is. Ms = log ( A / T) + 1.66 log D + 3.30. See more
Measuring earthquakes. Scientists use two values to describe the size of an earthquake – magnitude and intensity. Magnitude. The magnitude of an earthquake is a measure of the total amount of energy released by the ground movement at its source. It is commonly determined by analysing the shaking recorded on several seismographs.These two ratings describe the power of the earthquake from two different perspectives. The most common standard of measurement for an earthquake is the Richter scale, developed in 1935 by Charles F. Richter of the California Institute of Technology. The Richter scale is used to rate the magnitude of an earthquake -- the amount of energy …
The severity of an earthquake is measured on a Richter scale. It is logarithmic scale that measures the magnitude of an earthquake. The scale ranges from 1 to 10, with each increase in number indicating a tenfold increase in ground motion.
