What It Is

Sliding-window Gutenberg-Richter b-value over ~20k SoCal M≥1.5 earthquakes 2019-2023 --- low dynamic range (b ≈ 0.5-1.5), strongly autocorrelated, stress-sensitive (USGS FDSN)

Interpretation

Standard analysis sees: left-skewed. The atlas detects no named structure beyond this. It sits beside Seismograph (ANMO) in the atlas (standard-bank rank 21) — a neighbor conventional features miss.

What the atlas adds

Nothing beyond the standard reading — this source’s structure is already captured by standard features; the atlas adds no named residual.
