Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## USGS Volcano Status Scraper — Alert Levels & Aviation Color Codes Pull every USGS-monitored U.S. volcano in one structured dataset: current ground alert level (NORMAL / ADVISORY / WATCH / WARNING), aviation color code (GREEN / YELLOW / ORANGE / RED), the responsible USGS observatory, and the most recent VONA / Information Statement notice. Powers aviation routing tools, hazards dashboards, geoscience apps, and emergency management pipelines. The USGS Volcano Hazards Program continuously monitors more than 60 U.S. volcanoes and publishes alert states through the HANS public feed. This actor turns that feed into clean rows you can plug into anything from a Slack alert to a national-level dashboard. ### What you get | Field | Description | |-------|-------------| | `volcanoName` | Common volcano name (e.g. "Kilauea", "Mount St. Helens") | | `vnum` | USGS Smithsonian volcano number (5–6 digits) | | `volcanoCode` | USGS short code (e.g. "ak6", "hi1") | | `alertLevel` | Ground alert level — `NORMAL`, `ADVISORY`, `WATCH`, `WARNING` | | `colorCode` | Aviation color code — `GREEN`, `YELLOW`, `ORANGE`, `RED` | | `isElevated` | `true` if volcano is currently above NORMAL (cross-checked against USGS elevated list) | | `observatoryFullName` / `observatoryAbbr` | Responsible USGS observatory (AVO, CVO, HVO, YVO, LVO) | | `lastNoticeUtc` | UTC timestamp of the most recent notice | | `lastNoticeUrl` | Direct link to the notice on volcanoes.usgs.gov | | `lastNoticeApiUrl` | JSON endpoint for the full notice text | ### How to scrape USGS volcano status 1. Click **Try for free** to start a default run (returns ~67 monitored volcanoes). 2. Optionally filter: - `observatoryFilter` — `"avo"`, `"cvo"`, `"hvo"`, `"yvo"`, `"lvo"` - `minAlertLevel` — `"ADVISORY"`, `"WATCH"`, `"WARNING"` (only return at-or-above) - `elevatedOnly` — `true` returns only volcanoes currently above NORMAL/GREEN 3. Run on a schedule (every 15–60 min) to track alert changes. ### Pricing $0.003 per record. A full pull (~67 monitored volcanoes) costs about $0.20 in result fees plus minimal compute. Apify compute is billed separately. ### Example input ```json { "elevatedOnly": true, "minAlertLevel": "ADVISORY", "maxResults": 0 } ```` ### Example output ```json { "volcanoName": "Kilauea", "vnum": "332010", "alertLevel": "WATCH", "colorCode": "ORANGE", "isElevated": true, "observatoryFullName": "Hawaiian Volcano Observatory", "observatoryAbbr": "hvo", "lastNoticeUtc": "2026-05-04 23:50:28", "lastNoticeUrl": "https://volcanoes.usgs.gov/hans-public/notice/DOI-USGS-HVO-2026-05-04T22:04:34+00:00", "sourceUrl": "https://volcanoes.usgs.gov/hans-public/api/volcano/getMonitoredVolcanoes" } ``` ### Use cases - **Aviation routing & dispatch** — Avoid airspace near ORANGE/RED color-coded volcanoes (ash-cloud risk). - **Insurance / reinsurance** — Track hazard exposure for catastrophe modeling. - **Emergency management** — Build a single-pane status board for elevated volcanoes. - **News & data journalism** — Detect alert-level changes immediately. ### Other actors you might like - `usgs-earthquake-scraper` — Live USGS earthquake feed. - `usgs-water-services-scraper` — Real-time stream gauge and groundwater data. - `noaa-ncei-climate-scraper` — NOAA daily climate observations. - `fema-disasters-scraper` — FEMA federally declared disasters. ### FAQ **Q: How often is the underlying feed updated?** A: USGS pushes a new notice as soon as observatory analysts publish it. The `getMonitoredVolcanoes` snapshot reflects the latest state for every monitored volcano. **Q: What's the difference between alert level and color code?** A: Alert level is the ground-hazard status (for nearby populations and emergency managers). The color code is the *aviation* hazard rating tied to ash-cloud risk. They usually move together but can diverge. **Q: Why are some volcanoes "UNASSIGNED"?** A: Some monitored volcanoes don't have published alert states between events. They still appear in the dataset for completeness. ### Legal Data is sourced from the public USGS Volcano Hazards Program HANS feed (`volcanoes.usgs.gov/hans-public`).
