How this service works
Volcano hazard API: every US volcano currently at an elevated alert level — alert level (NORMAL/ADVISORY/WATCH/WARNING), aviation color code, observatory, and latest notice time — as normalized JSON. Covers Alaska, Hawaii, the Cascades, Yellowstone, and the Mariana Islands. Use for aviation routing, hazard-monitoring dashboards, and risk-alert agents. Public-domain government data, cached 5 minutes. Returns an empty list when no volcanoes are elevated.
Output
A JSON list of all US volcanoes currently at elevated alert levels, each with volcano name, alert level (NORMAL/ADVISORY/WATCH/WARNING), aviation color code (GREEN/YELLOW/ORANGE/RED), the responsible observatory, and the timestamp of the latest notice. Returns an empty list when no volcanoes are elevated. Data is cached and refreshed every 5 minutes from USGS public-domain sources. Covers Alaska, Hawaii, the Cascades, Yellowstone, and the Mariana Islands.
Example use cases
Example prompt
“Are any US volcanoes currently under an elevated alert — like ADVISORY, WATCH, or WARNING — and if so, what are their aviation color codes and which observatory is tracking them?”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/volcano-activityWhen to prefer
Use this endpoint when you need a normalized, ready-to-parse JSON snapshot of current US volcano hazard status across all observatories. Ideal for aviation routing decisions, hazard-monitoring dashboards, or risk-alert agents that need alert levels and aviation color codes in one call. Prefer this over scraping USGS directly when you need structured JSON output, consistent schema, and multi-observatory coverage in a single request.
Side effects
- Empty list returned when no volcanoes are elevated — not an error, just no current hazards
- Payment failure if USDC balance insufficient for the $0.005 per-call fee
- Stale data up to 5 minutes old due to caching — not suitable for sub-minute monitoring
- No historical data — only current snapshot is available
- May not reflect very recent USGS updates within the cache window
