The Volcano Notification Service (VNS) is a free service that sends you notification emails about volcanic activity happening at U.S. monitored volcanoes.

You can customize the VNS to deliver notifications for certain volcanoes or a range of volcanoes, and you can also choose the 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).
