Volcano Notification Service
The Volcano Notification Service (VNS) is a free service that sends you notification emails about
volcanic activity happening at US monitored volcanoes.
You can customize the VNS to only deliver notifications for certain volcanoes, or range of volcanoes, as well
as choose the separate notification types you want to receive.
Notifications are issued by the five U.S. Volcano Observatories: Alaska (AVO), Cascades (CVO), Hawaiian (HVO), California (CalVO), and Yellowstone (YVO).
