Equirectangular projection. Basemap: Natural Earth (public domain, world-110m) — geographic context only, never an official alert boundary. Official areas are drawn only when the agency product includes a valid polygon or circle. A USGS tsunami flag is never drawn as an alert.

A stale or failing feed does NOT mean all-clear. This app produces no forecasts. Everything shown comes directly from the agencies.
