From the Document: "In 2019, Congress authorized a National Volcano Early Warning and Monitoring System (NVEWS; Section 5001 of P.L. 116-9; 43 U.S.C. 31k). The law directs the Secretary of the Interior to establish NVEWS to monitor volcanoes, warn U.S. citizens of volcanic activity, and protect citizens from 'undue and avoidable harm' resulting from volcanic activity. In FY2022, Congress provided funds to begin implementation of NVEWS. Many in Congress are interested in a volcano early warning and monitoring system because the nation faces threats from many active volcanoes. The U.S. Geological Survey (USGS, a bureau within the Department of the Interior) published an assessment in 2018 of the volcanic threat and indicated that better monitoring is necessary for effective warnings. The USGS volcanic threat assessment assigned five threat levels (very high, high, moderate, low, and very low) to 161 volcanoes in 14 states and U.S. territories[.]"
