![“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/q/i/fb0/charles-francis-richter-15733_broadcasting_magnitude-may-be-compared-to-the-power-o_594188.png)
“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 from the source; it will also depend on local conditions at the point of observation, and to some extent on the conditions along the path from source to that point.”
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Magnitude quantifies energy release; intensity measures observed shaking at a location, both affected by distance and local conditions.
In simple terms: Magnitude is energy; intensity is local shaking.
Key Takeaway

A Different Perspective
Intensity can be misleading without context of distance and site effects.
