Tsunami Warning, Research, and Education Act of 2025

This bill, the Tsunami Warning, Research, and Education Act of 2025, reauthorizes and significantly expands the existing Tsunami Warning and Education Act. It adds a strong emphasis on research, data management, and education, in addition to warning operations. Key changes include integrating and modernizing data systems (including real-time data streams from GNSS networks and other sources), expanding the geographic scope to include Pacific, Arctic, and Atlantic tsunami-prone regions, and enhancing collaboration among federal agencies (NOAA, USGS, NASA, NSF), with implications for data sharing, decision support, and public communication. The bill also strengthens public alerting pathways (including IPAWS) and requires improved inundation mapping, coastal modeling, and education/outreach to coastal communities. It lays out funding levels and annual reporting requirements to Congress. In short, the bill aims to boost the reliability and timeliness of tsunami warnings, expand research and data infrastructure, and improve public preparation and mitigation across more U.S. coastlines, while formalizing interagency coordination and accountability.
