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 a range of volcanoes, as well as choose the separate notification types you want to receive.
Notifications are issued by these U.S. Volcano Observatories: Alaska (AVO), California (CalVO), Cascades (CVO), Hawaiian (HVO), Northern Marianas Islands (NMI) and Yellowstone (YVO).
For help with VNS please email vnshelp@usgs.gov.
