• list_notices(volcano_slug?, limit?) — recent activity notices.

Data source

https://volcanoes.usgs.gov/hans-public/api/ — USGS HANS public feed.

Tools

• list_volcanoes — List every US volcano monitored by USGS with current alert level (Normal/Advisory/Watch/Warning) and aviation color code (Green/Yellow/Orange/Red). Filter optionally by observatory.
• list_elevated — List only the volcanoes currently above Normal/Green status (i.e., elevated unrest or eruption). Smallest practical fingerprint of “what’s happening right now.”
