Where do these numbers come from?
Every figure is computed from the public reading log at /api/history.json, using the formulas on the methodology page. Each hourly reading has a hash-chained receipt you can verify in your browser. SIREN measures how much is happening, not how bad it is. Levels run from 5 (quietest) to 1 (loudest) and describe observable activity tempo against this index’s own record. They are not a probability of harm.
