This bill reauthorizes the federal Tsunami Warning and Education program and recasts it to place research and data management alongside operational warning responsibilities. It changes the statutory title to add “research,” updates program purposes, and directs NOAA to improve data quality, archiving, and interagency coordination for tsunami detection, forecasting, and communications.
The measure also requires new technical and planning work—coordinated GNSS support, updated inundation mapping using coastal digital elevation models (DEMs), social and behavioral research on alert effectiveness, and clarified roles for delivering messages via the Integrated Public Alert and Warning System (IPAWS). It authorizes $32 million per year for fiscal 2026–2030 and specifies minimum shares for state-level mitigation and research funding, shifting how federal funds flow to states and investigators.
At a Glance
What It Does
The bill expands the Tsunami Warning and Education Act to add research and data management responsibilities, mandates modernization of warning products and data systems, requires interagency collaboration (NOAA, USGS, NASA, NSF), and clarifies IPAWS responsibilities for tsunami alerts.
Who It Affects
Federal agencies running observation networks and warning centers, state tsunami hazard mitigation programs and emergency managers, coastal communities that rely on inundation maps, and the academic and vendor research community that supplies models and observing systems.
Why It Matters
It formalizes the research-to-operations pipeline, demands standardized and archived data for reproducible forecasting, and ties federal funding to state mitigation capabilities — creating both technical upgrades and new administrative obligations for NOAA and partners.

What This Bill Actually Does
The bill rewrites the program’s mission to pair operational warning responsibilities with explicit research, data management, and archiving duties. NOAA must now treat data and metadata as a program asset: ensuring quality, standardized formats, accessible archives, and compliance with federal evidence and records laws.
That is designed to make forecasting models reproducible, enable research to build directly on operational data, and help future users find and reuse outputs and observations.
On the sensing side, the statute brings the global navigation satellite system (GNSS) network into the set of observations NOAA must use and support, and it formalizes a cooperative role for USGS, NASA, and NSF. The bill directs NOAA and those agencies to provide near-real-time GNSS streams and to consider integrating tsunami notifications into the USGS Earthquake Early Warning system.
It also expands the list of required inputs and updating responsibilities for coastal monitoring, buoy and tide data, and other ocean observing assets.For warnings and communications, the bill requires NOAA to evaluate alert terminology, timing, and effectiveness with social and behavioral scientists and to update the alert-level system if it fails to produce intended public responses. It directs NOAA to coordinate message generation systems, migrate to modern processing platforms, standardize products and procedures across regional centers, maintain fail-safe backup capability (with biannual drills), and clarify how NOAA, FEMA, and the FCC share decision authority and operational responsibilities for IPAWS dissemination.The mitigation and mapping provisions push NOAA and partners to produce higher-resolution coastal digital elevation models (DEMs) and updated inundation maps for underserved regions, assess tsunami-driven sediment transport and debris impact on critical infrastructure, and prioritize mapping for ports, harbors, and at-risk shorelines.
The research title requires a research-to-operations plan updated every 36 months, a public data portal, decision-support tool development, and explicitly funds social and behavioral science to improve public response to alerts.Finally, the authorization sets a fixed annual funding level of $32 million for fiscal years 2026–2030 and prescribes minimum allocations: at least 27% for state-level mitigation activities and at least 8% to the tsunami research program. The bill adds new reporting requirements to congressional committees to track standardization, migration of message systems, organizational alignment, and timelines for completing those changes.
The Five Things You Need to Know
The bill inserts “Research” into the program title and requires NOAA to manage, archive, and make data and metadata available under federal evidence and records laws.
It requires NOAA to ingest and support real-time GNSS data streams and to formalize cooperative roles with USGS, NASA, and NSF — including evaluating incorporation of tsunami notifications into the USGS Earthquake Early Warning System.
The statute mandates an evaluation of tsunami alert terminology and timing with social and behavioral scientists and directs updates to alert levels if communities do not respond as intended.
NOAA must produce high-resolution coastal digital elevation models (DEMs), update inundation maps (prioritizing underserved ports/shorelines), and evaluate tsunami-driven sediment and debris impacts on critical infrastructure.
The bill authorizes $32,000,000 per year for FY2026–2030 and requires not less than 27% go to state-level mitigation activities and not less than 8% to the tsunami research program.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Establishes the Act’s public name: the “Tsunami Warning, Research, and Education Act of 2025.” This is nominal but signals Congress’s intent to treat research and data management as core statutory purposes rather than discretionary add-ons.
Add research and data stewardship to core purposes
The bill changes the statutory title to include “research” and expands the list of program purposes to require timeliness and accuracy and explicit data and metadata stewardship. Practically, that obligates NOAA to adopt recordkeeping and data sharing practices consistent with the Foundations for Evidence-Based Policymaking Act, which affects how datasets are cataloged, preserved, and made discoverable for operations, research, and public use.
Modernize inputs, coordination, and warning products
This substantial amendment requires NOAA to integrate GNSS observations, to improve data quality management, and to standardize products and decision-support aids for local and regional users. It creates a formal cooperative role for USGS, NASA, and NSF with specific expectations (real-time GNSS support, assessment of partner warning systems, and incorporation into USGS early warning where practicable). The section also requires updating inundation maps and warns centers to migrate message generation to NOAA’s advanced processing systems, creating a multi-year engineering and coordination workload.
Reorganize center responsibilities, require backups and outreach
The bill reassigns responsibilities for regional warning centers, drops previous language limiting geographic responsibility, and requires fail-safe backup capabilities with biannual drills. It tightens monitoring requirements (including coastal and sea-level data), requires a tsunami coordinator role to liaise with partners, and obliges National Weather Service offices to run outreach to prepare coastal communities. It also establishes recurring reporting to congressional committees on standardization, system migration, organizational realignment, and timelines — creating accountability milestones.
Clarify IPAWS roles and decision-making
The statute directs NOAA, FEMA, and the FCC to document responsibilities and the decision flow for using IPAWS to deliver tsunami alerts. That forces a cross-agency operational agreement describing who decides to push alerts, who formats and transmits them, and how conflicts or edge cases (e.g., cross-jurisdictional events) are resolved — an administrative but operationally critical deliverable.
Expand mapping and social/behavioral priorities
Amendments require coastal DEMs, higher-resolution inundation mapping, and new analyses of tsunami-driven sediment transport and debris impacts on critical infrastructure. They also explicitly add behavioral science to social research priorities, pushing mitigation partners to factor human responses into evacuation planning and public messaging infrastructure.
Data portal, decision tools, and a research-to-operations plan
The research title gains concrete deliverables: NOAA must develop and maintain a research data portal, prioritize R&D and transition plans, and update a formal research and development plan every 36 months. This creates programmatic expectations for funding solicitations, partnerships with universities and federal labs, and explicit pathways to move validated research models into operations.
Funding level and minimum allocations
Authorizes $32 million annually for FY2026–2030 and prescribes minimum allocation shares: at least 27% for state-level mitigation under the National Tsunami Hazard Mitigation Program and at least 8% for the tsunami research program. Those floors will direct how NOAA budgets interpret federal funding and constrain internal trade-offs.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Coastal communities and local emergency managers — receive updated inundation maps, clearer alert terminology informed by behavioral research, and improved decision-support products tailored to evacuation needs.
- State tsunami mitigation programs — gain guaranteed minimum funding (at least 27% of annual appropriations) to support mapping, outreach, and preparedness projects at the state level.
- Academic and applied research community — get sustained support via a formal research program, a mandated public data portal, prioritized research-to-operations pathways, and a fixed share of appropriations for research.
- Federal science agencies (USGS, NASA, NSF) — receive formal recognition in statute to provide GNSS and other observational support and partner on research transitions, which can smooth interagency R&D and data sharing.
- Ports, harbors, and infrastructure planners — will benefit from directed assessments of tsunami-driven sediment, debris impacts, and higher-resolution DEMs that improve risk analysis and engineering design.
Who Bears the Cost
- NOAA and its regional warning centers — must invest in system migration, GNSS ingestion, standardized product development, data archiving, and staffing to meet new coordination and reporting duties.
- Federal partners (FEMA, FCC) — need to negotiate and document IPAWS decision authorities, which requires technical, legal, and operational work and could change existing workflows.
- State and local agencies — while receiving minimum funding, they still face planning, matching, or implementation costs to use DEMs and updated maps effectively, including potential needs for new training and local outreach.
- Congressional appropriations — the $32M authorization establishes a ceiling that may be insufficient; reallocating fixed percentages to states and research reduces NOAA’s flexibility to fund other operational priorities.
- Private data providers and vendors — may need to adapt data formats, provide real-time GNSS streams, or support interoperability to meet the new standardized data and metadata requirements.
Key Issues
The Core Tension
The bill balances the need for fast, reliable, and widely understood tsunami warnings against the technical, organizational, and budgetary realities of making data, models, and communications interoperable — improving one (speed or uniformity) can undermine the other (local relevance or operational flexibility), and the statute forces choices without fully funding all downstream obligations.
The bill pushes hard on data standardization and research-to-operations, but it leaves open how NOAA will balance centralized standard products with the need for regionally tailored warnings. Standardization speeds interoperability and reduces duplication, yet overly prescriptive national products can erode local nuance needed for effective evacuations.
Implementers will need to define where standardization ends and local customization begins.
The GNSS and interagency cooperation directives are operationally valuable but technically and legally complex. Integrating real-time GNSS streams across NOAA, USGS, NSF, and NASA requires sustained funding, agreed data formats, and service-level agreements.
Similarly, clarifying IPAWS responsibilities reduces ambiguity but could reveal jurisdictional frictions: FEMA owns IPAWS infrastructure, the FCC sets EAS rules, and NOAA owns the operational product — reaching durable operational agreements will demand time and negotiation.
Finally, the authorization level and the mandated allocation floors create competing pressures. The $32M annual authorization is explicit, but whether it covers the engineering, data-archiving, GNSS support, mapping, and research costs at scale is uncertain.
Fixed percentage floors (27% to states, 8% to research) improve predictability for recipients but reduce NOAA’s ability to shift funds to emergent operational needs, potentially producing unfunded gaps or delays in migration and standardization efforts.
