The Volcano Notification Service (VNS) is a system used by the United States Geological Survey (USGS) and other agencies to provide timely and crucial information about volcanic activity and potential hazards to those who might be affected. VNS is designed to monitor and notify the public, emergency responders, and other stakeholders about volcanic events, including eruptions, ash plumes, and other volcanic hazards.
