To amend the John D. Dingell, Jr. Conservation, Management, and Recreation Act to reauthorize the National Volcano Early Warning and Monitoring System.

The bill would reauthorize the National Volcano Early Warning and Monitoring System by amending the John D. Dingell, Jr. Conservation, Management, and Recreation Act. It would extend the USGS-led program — which includes a volcano monitoring network, volcano observatories, a national data center, and external research grants — from its prior authorization window to fiscal years 2026 through 2029. It would also replace the named agencies in the statute with the relevant cabinet secretaries for greater flexibility.

The bill would set a specific annual funding figure of $470,000 for the Secretary of Commerce's (NOAA's) participation in the system for each of fiscal years 2026 through 2029, replacing the prior open-ended "such sums as may be necessary" language. It makes no other substantive changes to how the system operates or is governed.

The U.S. Geological Survey and its volcano observatory staff who operate the monitoring network; the National Oceanic and Atmospheric Administration, which collaborates on the system; researchers who receive external grants through the program; and communities living near active volcanoes — particularly in Alaska, Hawaii, the Pacific Northwest, and other volcanically active regions — who benefit from early warning alerts.

Without reauthorization, the statutory funding authority for the volcano monitoring system would lapse, potentially disrupting operations at USGS volcano observatories and reducing NOAA's funded collaboration. Setting a fixed annual amount ($470,000) for NOAA replaces the prior indefinite funding language, giving that agency a defined budget baseline for its role in the system through FY2029.

The USGS would continue operating the monitoring network, observatories, and national data center in collaboration with NOAA under the reauthorized authority. NOAA would receive $470,000 annually from FY2026 through FY2029 for its role. The bill itself is a narrow statutory amendment; no new rulemaking or reporting requirements are created. External research grants authorized by the underlying program would continue under the reauthorized framework.
