## Summary

**This bill would reauthorize and upgrade the tsunami warning, research, and education programs to prioritize _timely tsunami warnings_ and to make tsunami data and metadata fully available for operations, research, education, and mitigation.** - Coastal communities and emergency managers: Would get faster, clearer alerts, more sensors and data streams including GNSS, tidal gauges, buoys, and updated inundation and probabilistic-hazard maps to guide evacuations and vertical-evacuation planning. - Indian Tribes, Tribal organizations, and Native Hawaiian organizations: Would be explicitly included in program participation, consultation, outreach, data sharing, and education efforts. - NOAA centers, researchers, and federal partners: Would face new requirements for supercomputing, staffing, migration to a new processing system, a Tsunami Warning Coordinator at each center, and multiple GAO/Comptroller General studies and reporting timelines. *Would authorize $35.0 million per year for fiscal years 2027–2031, increasing federal spending and directing at least 27% to the hazard mitigation program and at least 8% to the research program.*
