What It Is

Real USGS earthquake magnitudes --- Gutenberg-Richter distribution, ~77k M4.0+ events 2020-2024 (USGS ANSS ComCat)

Interpretation

Standard analysis sees: right-skewed. The atlas finds no named structure, but the source is distinctively extreme on Zipf–Mandelbrot (8-bit):hapax_ratio (+2.8z) — beyond what the standard bank predicts for it.
