The United States Geological Survey National Volcanic Threat Assessment is a report containing a ranked list of active volcanoes in the United States posing hazardous risks to the American population. [1] The report was published by the United States Geological Survey in 2005 [2] and revised in 2018. [3]
The Volcano Hazards Program is a program directed by the USGS that monitors the activity of volcanoes and the public awareness of eruptions. Under the mandate of the Robert T. Stafford Disaster Relief and Emergency Assistance Act (Stafford Act), the Volcano Hazards Program monitors active and potentially active volcanoes, assesses their hazards, responds to volcanic crises, and conducts ...
In October 2006, the United States Geological Survey (USGS) adopted a nationwide alert system for characterizing the level of unrest and eruptive activity at volcanoes. The system is now used by the Alaska Volcano Observatory, the California Volcano Observatory (California and Nevada), the Cascades Volcano Observatory (Washington, Oregon and Idaho), the Hawaiian Volcano Observatory and the ...

The "very high" risk volcanoes are in Alaska, Washington, Oregon, California, and Hawaii, with the most dangerous being Kilauea. Some volcano monitoring has been performed by the Volcano Hazards Program, directed by the USGS, but the program lacks sufficient funding to properly close the monitoring gap. [8]
A volcanic hazard is the probability a volcanic eruption or related geophysical event will occur in a given geographic area and within a specified window of time. The risk that can be associated with a volcanic hazard depends on the proximity and vulnerability of an asset or a population of people near to where a volcanic event might occur.
