Frequently Asked Questions

Which volcanoes does WeatherAI monitor?

WeatherAI tracks US volcanoes through the USGS Volcano Hazards Program, including status levels, alert colors, and activity updates as the observatories publish them.

What do volcano alert levels mean?

The USGS uses four alert levels: Normal (typical background activity), Advisory (elevated unrest), Watch (heightened or escalating unrest), and Warning (highly hazardous eruption imminent or underway).

Does the app track volcanic ash?

Volcanic ash advisories reach WeatherAI through the SIGMET layer on the map, which is included with Standard and Pro. The volcano status views themselves are free on every tier.
