The quake was felt. Earthquake - Earthquake - Earthquake magnitude: Earthquake magnitude is a measure of the “size,” or amplitude, of the seismic waves generated by an earthquake source and recorded by seismographs.

(The types and nature of these waves are described in the section Seismic waves.) Because the size of earthquakes varies enormously, it is necessary for purposes of comparison to compress the. Thus, stronger rock material, or a larger area, or more movement in an earthquake will all contribute to produce a larger magnitude.

Then, Moment Magnitude (M W) = 2/3 log 10 (M O) - See the Magnitude Types Table (below)for a summary of types, magnitude ranges, distance ranges, equations, and a brief description of each.

Geological Survey. The earthquake occurred less. The largest earthquakes on these scales range up to about magnitude 8 or 9. Using sensitive instruments, seismologists have detected earthquakes as small as magnitude –3 or –4. An earthquake with magnitude of –3 is 1, times smaller than magnitude 0, the smallest number on the original Richter scale.

Expand "Advanced Options" and fill in the "Circle. Historical earthquakes is a list of significant earthquakes known to have occurred prior to the beginning of the 20th century.

As the events listed here occurred before routine instrumental recordings, they rely mainly on the analysis of written sources. There is often significant uncertainty in location and magnitude and sometimes date for each earthquake.

Fradkin has authored books ranging from Alaska, California and Nevada, with topics ranging from water conservation, earthquakes, and nuclear weapons. InFradkin was given the Californiana Award by the Commonwealth Club of California/5.

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.
