M4.5

Floored at M4.5, where USGS coverage is globally complete. Below that, density tracks instrument placement more than geology.

Pale rings are the great earthquakes since 1900 — Chile 1960, Alaska 1964, Sumatra 2004, Tōhoku 2011. They sit outside the archive window, so the month and depth filters leave them alone.

Overlapping events brighten, so density reads as luminance.
