Quotes

I usually point out that most loss of life and property has been due to the collapse of antiquated and unsafe structures, mostly of brick and other masonry. Charles Francis Richter
We would have been happy if we could have assigned just three categories, large, medium, and small; the point is, we wanted to avoid personal judgments. It actually turned out to be quite a finely tuned scale. Charles Francis Richter
If the assumptions used in calculating energy are changed, then this seriously affects the final result, even though the same body of data might be used. Charles Francis Richter
Charles Francis Richter quote: "Don't wait for extraordinary circumstance to do good; try to..."
Don't wait for extraordinary circumstance to do good; try to use ordinary situations. Charles Francis Richter
Intensity like signal strength will generally fall off with distance from the source, although it also depends on the local conditions and the pathway from the source to the point. Charles Francis Richter
Charles Francis Richter quote: "Refining is inevitable in science when you have made..."
Refining is inevitable in science when you have made measurements of a phenomenon for a long period of time. Charles Francis Richter
By moving them vertically, a representative mean curve could be formed, and individual events were then characterized by individual logarithmic differences from the standard curve. Charles Francis Richter
For example, some stars put out large amounts of energy in the infrared part of the spectrum, so that this can produce a different relative magnitude rating than using light energy from the middle of the spectrum. Charles Francis Richter
As seismologists gained more experience from earthquake records, it became obvious that the problem could not be reduced to a single peak acceleration. In fact, a full frequency of vibrations occurs. Charles Francis Richter
There is another common misapprehension that the magnitude scale is itself some kind of instrument or apparatus. Visitors will frequently ask to 'see the scale.' Charles Francis Richter
Incidentally, the usual designation of the magnitude scale to my name does less than justice to the great part that Dr. Gutenberg played in extending the scale to apply to earthquakes in all parts of the world. Charles Francis Richter
From here, it becomes an engineering problem; the engineer considers the ground motion that will occur and evaluates the requirements of the proposed structure in the light of the local foundation conditions. Charles Francis Richter
Emphasis was usually put on the horizontal acceleration factor, for the simple reason that ordinary structures have a built-in safety factor for the vertical component; that is, gravity. Charles Francis Richter
What emerged, of course, was that the magnitude scale presupposed that all earthquakes were alike except for a constant scaling factor. And this proved to be closer to the truth than we expected. Charles Francis Richter
Charles Francis Richter quote: "My amateur interest in astronomy brought out the term..."
My amateur interest in astronomy brought out the term 'magnitude,' which is used for the brightness of a star. Charles Francis Richter
