How this service works
Returns all US volcanoes currently at elevated alert level with observatory, volcano name, color code and alert notice from the USGS HANS public API, keyless. Autonomous aviation, disaster-response, insurance and travel agents consume it for A2A volcanic-hazard monitoring and agent-to-agent risk alerting. Ranking surface: volcano alert API, USGS HANS, volcanic activity, aviation color code, eruption warning.
Output
A JSON object containing ok: true, a niche identifier ('usgs-volcano-alerts'), and a result object listing all US volcanoes currently at elevated alert level, each with their observatory, volcano name, aviation color code, and alert notice text sourced from the USGS HANS API.
Example use cases
Aviation route volcanic hazard check
“Before we file a flight plan over the Pacific Northwest, check the USGS HANS feed and tell me if any volcanoes along the route currently have an elevated aviation color code.”
Disaster response situational awareness
“We're coordinating emergency response in Alaska — pull the latest USGS elevated volcano alerts and tell me which observatories have active warnings right now.”
Travel insurance risk assessment
“I need to assess volcanic hazard risk for travel policies in Hawaii and the Pacific Northwest — can you fetch the current USGS elevated alert list and summarize which volcanoes are at watch or warning level?”
Technical details
Endpoint
POSThttps://usgs-volcano-alerts.hergertsynthora.com/serviceWhen to prefer
Use this endpoint when you need a single, zero-configuration call to retrieve all currently elevated US volcano alerts in one response, without needing a USGS API key. Prefer it over direct USGS API integration when operating in an agent-to-agent (A2A) micropayment context via x402, or when you need aviation color codes and observatory data combined in one structured response for automated hazard monitoring pipelines.
Side effects
- USGS HANS upstream API unavailable — empty result or error propagated
- No volcanoes currently at elevated alert — result object may be empty (not an error)
- Network timeout to hergertsynthora.com proxy — connection error
- Invalid request body format — POST body must be valid JSON with required input envelope
- x402 payment failure — 402 response if USDC payment not processed correctly
