What is it about?
The relationship between the Gutenberg-Richter’s b-value and the rupture area versus maximum slip scaling is found. The b-value makes a link between earthquake statistics (the GR law) and physics (earthquake rupture dynamics), or earthquake source characteristics. Observed b-value ranges are explained in terms of the scaling. It is shown that the Gutenberg-Richter frequency-magnitude relation with its b-value can be treated as the Gibb’s distribution for occurrence of an earthquake with magnitude m, which is the most uniform distribution under the constraint that the mean magnitude (or inverse the b-value) is fixed.

Why is it important?
The paper sheds light on honest earthquake forecasting problem. It explains how the observed earthquake statistics depend on different source characteristics: its geometry, plate coupling and asperity distributions, amounts of sediments and fluids, etc…
Perspectives
This work is unique for me. The main idea concerning the G-R law in the MEP context ocurred 25 years ago, after reading some papers on MEP by E.T.Jaynes (and by H.Haken). Then, about 20 years later, I considered the problem anew after reading Jaynes’ “Probability theory”. After next 5 years I decided to publish a paper. A friend of mine gave me a feedback that she loved the paper. I was surprised, so I read my paper, finding much more then I had written. I hope it can inspire you.
