Magnitudes are based on a logarithmic scale (base 10). What this means is that for each whole number you go up on the magnitude scale, the amplitude of the ground motion recorded by a seismograph goes ...

The logarithmic scale used initially here allows for an easier comparison of the exoplanets. The linear scale shows how shallow the habitability zone is.

DF Folded scale, x*pi LLn Log-log scales, e^a*x LL0n Log-log scales, e^-a*x L Log scale, log10(x), linear S Sine and cosines scale, sin(x) T Tangent scale, tan(x) If you’ve ever tried to ...
