Definition of Richter scale in English:

Richter scale

nounˈrɪktəˈrɪktər ˌskeɪl

Geology

A numerical scale for expressing the magnitude of an earthquake on the basis of seismograph oscillations. The more destructive earthquakes typically have magnitudes between about 5.5 and 8.9; it is a logarithmic scale and a difference of one represents an approximate thirtyfold difference in magnitude.
〔地质〕里克特震级，里氏震级
Example sentencesExamples
- Nine on the Richter scale indicates an earthquake of absolutely awesome destructive power.
- In the last hundred years, there have been about 20 earthquakes of 6 to 7.7 magnitude on the Richter scale under the sea.
- Each unit on the Richter scale represents a thirty-fold increase of energy.
- The earthquake had a magnitude of 7.2 on the Richter scale.
- Seismographs and the Richter scale are just one type of graph that scientists use to measure the world.

Origin

1930s: named after Charles F. Richter (1900–85), American geologist.
