Apr 19, 2024 · Richter 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.
Earthquake intensity measures how strongly the earthquake impacts a specific location. In the light bulb analogy, it is the brightness with which you perceive the light at a place in a room.

May 12, 2024 · Earthquake, any sudden shaking of the ground caused by the passage of seismic waves through Earth’s rocks. Earthquakes occur most often along geologic faults, narrow zones where rock masses move in relation to one another. Learn more about the causes and effects of earthquakes in this article.
The outcome for this section will be covered by several Open Educational Resources. Review and reflect on each one as you prepare to complete the assessment for this module. Reading: Earthquake Intensity. Reading: Magnitude vs. Intensity.
Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept. The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby seismograph stations.

Mar 10, 2019 · Earthquakes can be measured using seismic intensity scales, which assess how bad the tremors are on a scale from I to XII.
