Title 43 › Chapter 2— UNITED STATES GEOLOGICAL SURVEY › § 31k
Create a National Volcano Early Warning and Monitoring System inside the United States Geological Survey to watch volcanoes, give warnings, and help protect people from volcanic danger. Key terms: "Secretary" means the Secretary acting through the USGS Director; "Secretary of Commerce" means the Secretary of Commerce acting through the Under Secretary for Oceans and Atmosphere; "System" means the National Volcano Early Warning and Monitoring System; "Volcanic Ash Advisory Center" means an ICAO-designated center that warns aviation about volcanic ash. The System must organize and modernize volcano observatory monitoring (including the Alaska, California, Cascades, Hawaiian, and Yellowstone observatories), join them into one interoperable network, and use NOAA expertise (including the Volcanic Ash Advisory Centers) to observe and model ash, gases, aerosols, atmospheric and ocean chemistry. It must monitor all U.S. volcanoes based on their threat by upgrading existing networks, adding new ones, and using geodetic and other tools. The System must include a 24/7 national volcano watch office, a national data center, and a grants program for monitoring research. Modernization should use technologies like broadband seismometers, continuous GPS, satellite and airborne radar interferometry, acoustic pressure sensors, gas spectrometers, and uncrewed aerial vehicles. The Secretaries must make a memorandum of understanding for NOAA support. Within 180 days after March 12, 2019, the Secretary must send a 5-year management plan to Congress with yearly cost estimates, milestones, and partnership plans, and update it with NOAA cost estimates. The Secretary must create an advisory committee, may partner with universities and states, coordinate with DOT, FAA, NOAA, and FEMA, and report to Congress each year. Congress authorized $55,000,000 for USGS for fiscal years 2019 through 2023, and NOAA funding as needed for fiscal years 2023 through 2024; these funds must add to, not replace, other hazard funding.
