Access Information About Volcanic Conditions

When signs of volcanic unrest arise, USGS scientists post updates on the Volcano Hazards Program websites and send out notifications to people who have subscribed to the Volcano Notification Service. USGS staff also informs agencies on a call-down list and contacts the media. Volcanic unrest may not lead to an eruption, but if it does, it may take days, months, or years.

To ensure you become aware of volcanic unrest, register for the Volcano Notification Service (VNS) to receive regular volcano-activity updates, check various USGS information websites, or rely on traditional media.
