I suggested that we might compare earthquakes in terms of the measured amplitudes recorded at these stations, with an appropriate correction for distance. — Charles Francis Richter Copy Share Image
This is very similar to astronomy where different magnitudes are assigned to the brightness of an astronomical object, depending on the range of wavelengths being measured. — Charles Francis Richter Copy Share Image
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… — Charles Francis Richter Copy Share Image
Nothing is less predictable than the development of an active scientific field. — Charles Francis Richter Copy Share Image
The rose does not bloom without thorns. True, but would that the thorns did not outlive the rose. — Charles Francis Richter Copy Share Image
Refining is inevitable in science when you have made measurements of a phenomenon for a long period of time. — Charles Francis Richter Copy Share Image
As seismologists gained more experience from earthquake records, it became obvious that the problem could not be reduced to a single peak acceleration. In… — Charles Francis Richter Copy Share Image
No joy in nature is so sublimely affecting as the joy of a mother at the good fortune of a child. — Charles Francis Richter Copy Share Image
The laboratory routine, which involves a great deal of measurement, filing, and tabulation, is either my lifeline or my chief handicap, I hardly know… — Charles Francis Richter Copy Share Image
I repeatedly have to correct this belief. In a sense, magnitude involves steps of 10 because every increase of one magnitude represents a tenfold… — Charles Francis Richter Copy Share Image
Magnitude may be compared to the power output in kilowatts of a [radio] broadcasting station; local intensity, on the Mercalli or similar scale, is… — Charles Francis Richter Copy Share Image
From here, it becomes an engineering problem; the engineer considers the ground motion that will occur and evaluates the requirements of the proposed structure… — Charles Francis Richter Copy Share Image
If the assumptions used in calculating energy are changed, then this seriously affects the final result, even though the same body of data might… — Charles Francis Richter Copy Share Image
There is another common misapprehension that the magnitude scale is itself some kind of instrument or apparatus. Visitors will frequently ask to 'see the… — Charles Francis Richter Copy Share Image
![“Magnitude may be compared to the power output in kilowatts of a [radio] broadcasting station; local intensity, on the Mercalli or similar scale, is then comparable to the signal strength noted on a receiver at a given locality. Intensity, like signal strength, will generally fall off with distance…” quote by Charles Francis Richter](https://sms4smile.com/quotes/img-quotes/fb0/charles-francis-richter-15733_broadcasting_magnitude-may-be-compared-to-the-power-o_594188.jpg)
