What's actively dangerous right now, across every hazard type this site covers. Each section below pulls live data — see Related Pages for the full browsing experience per hazard type.

See US Volcano Alerts (USGS HANS) for the full alert-level reference and per-observatory breakdown.

Tsunami Warnings & Advisories

Live U.S. tsunami messages from the NOAA/NWS Tsunami Warning Centers.

[DataFeed: no records for feed 'tsunami-alerts']

If nothing renders above, no tsunami messages are currently active.

Volcanic Ash Advisories (VAAC)

Active Volcanic Ash Advisories from the Washington VAAC, structured directly from NOAA OSPO — not VolcanoDiscovery's re-published copy, which is filtered out of Volcano Activity in favor of this section (geohazardwatch#159).

Washington VAAC — 2 active advisories. Last updated: Tue, 28 Jul 2026 09:38:12 GMT.

Coverage note: Washington VAAC only (Americas, E. Pacific, Caribbean) — one of nine ICAO-mandated regional VAACs. The other eight are not yet integrated (geohazardwatch#5).

Wildfire Alerts

Highest-intensity high-confidence FIRMS/VIIRS detections globally, most intense first. Each entry is a single satellite detection, not a confirmed named fire — see geohazardwatch#161 for why this stays a threshold-only list rather than clustered events (real clustering work, not started) and geohazardwatch#169 for the pending reverse-geocoded place-name upgrade.

If nothing renders above, the firms-viirs feed source is not yet configured — see Wildfires for configuration details. The full interactive map, with every high-confidence detection plotted, is also on Wildfires.


Status: HANS, Tsunami, VAAC, and Wildfire sections all live. Wildfire entries are threshold-only detections, not clustered named events — see geohazardwatch#161.
