The correct answers are A) determined from the amplitude recorded by a single seismometer. C) represents the amount of energy released. D) uses a logarithmic scale.
The news media often report an earthquake's magnitude on the Richter scale. The following items are characteristics of a Richter earthquake magnitude: determined from the amplitude recorded by a single seismometer, represents the amount of energy released, and uses a logarithmic scale.
When measuring the scale of the magnitude of earthquakes, the Richter scale measures the scale od moderated size earthquakes. It was invented by two United States seismologists: Charles F. Richer and Beno Gutenberg. They developed the measure in California when they were researching from 1927 through 1936, in the Seismological Laboratory of the Carnegie Institution of Washington, in Pasadena, California.
