Characterized Quote by 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.”
About This Quote
Source Scientific Paper: Seismic Analysis Methodology, 1935
Describes a method to create a standard mean curve from vertical data and compare events using logarithmic differences.
In simple terms: Standard curve created from vertical data; events compared via log differences.
Key Takeaway
Use log differences to identify anomalies.

A Different Perspective
Requires accurate baseline data; may miss non‑logarithmic patterns.
![“[In plotting earthquake measurements] the range between the largest and smallest magnitudes seemed unmanageably large. Dr. Beno Gutenberg then made the natural suggestion to plot the amplitudes logarithmically.” quote by Charles Francis Richter](https://sms4smile.com/quotes/img-quotes/de2/charles-francis-richter-15733_drs_in-plotting-earthquake-measurements-the_1816208.jpg)
![“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)
