Quake Watch renders every earthquake from the live USGS feed as a pulsing marker at its exact epicentre on a full screen map. The open source Leaflet library plots each event on OpenStreetMap dark tiles, with marker size and colour scaled to magnitude.

Markers pulse on a two second cycle. Great quakes pulse in deep red, major in red, strong in amber and moderate in cyan. The incident list below the map groups events by what is happening now, what happened recently and major events, each with an expandable detail panel.

The proof strip shows the answer stamped by the live AffixIO API: a proof id, an audit id, the policy version, and an ML-DSA-65 signature over the payload digest. That is the same post-quantum signature family the production platform uses.
