Tsunami Warning, Research, and Education Act of 2025

HR 4073 reauthorizes and updates the Tsunami Warning and Education Act to modernize U.S. tsunami warning systems. It requires NOAA to improve data management (including real-time GNSS network data), update inundation maps, evaluate alert terminology with communities, and integrate tsunami warnings into the USGS Earthquake Early Warning System. The bill mandates $32 million annually (2026-2030) for these efforts, with 27% funding state-level tsunami hazard mitigation programs and 8% supporting tsunami research. This directly affects coastal communities at risk, NOAA warning centers, and federal agencies like USGS and NASA through enhanced forecasting, data sharing, and standardized warning protocols.
