National Earthquake Hazards Reduction Program Reauthorization Act of 2025

The National Earthquake Hazards Reduction Program Reauthorization Act of 2025 reauthorizes and updates the federal program to reduce earthquake risks, explicitly including Tribal governments in program requirements. Key provisions require seismic evaluations for high-risk buildings, improve earthquake early warning systems, and provide technical assistance to state and local governments for building retrofits. The bill authorizes $10.59 million annually for the program, $100.9 million for the US Geological Survey, and $58 million for the National Science Foundation through 2028. This legislation directly affects federal agencies, state and local governments, Tribal governments, and communities in earthquake-prone areas by strengthening earthquake resilience measures and response planning.

Introduced in Senate Engrossed in Senate · 13 edits · Jan 5, 2026
MAJOR
The Senate engrossed version of S 320 (National Earthquake Hazards Reduction Program Reauthorization Act of 2025) makes several substantive changes from the introduced version: it expands scope to include Tribal governments throughout, adds evaluation and retrofitting as covered building activities, reduces funding levels across multiple program lines by roughly 10-20 percent, removes reference to climate compounding effects on earthquake hazards, tightens implementation language for agency recommendations, and adds new funding control provisions requiring deficit reduction for cancelled appropriations.
SCOPE

Replaced '50 States, and the Commonwealth of Puerto Rico' with 'States and Tribal jurisdictions,' broadening the bill's geographic and governmental scope to explicitly include Tribal jurisdictions.

Throughout the bill, references to 'and local' governments were changed to ', local, and Tribal' governments, extending program responsibilities and coordination requirements to include Tribal governments.

Removed 'and the compounding effects of climate on these hazards' from the list of multiple earthquake-associated hazards (liquefaction, tsunamis, landslides, structural fires).

DEFINITION

Added a new definition of 'Tribal government' referencing section 421 of the Congressional Budget Act of 1974 (2 U.S.C. 658).

Replaced specific reference to 'Historically Black Colleges and Universities and those serving large proportions of Hispanics, Native Americans, Asian-Pacific Americans, and other underrepresented populations' with a cross-reference to section 371(a) of the Higher Education Act of 1965 (20 U.S.C. 1067q(a)).

REQUIREMENT

Expanded covered building activities from 'and construction' to ', construction, evaluation, and retrofitting' in multiple sections, adding evaluation and retrofitting as explicitly covered activities.

Tightened implementation language: changed from 'execute research, projects, grants, and other activities that support, promote, advance, or otherwise implement the recommendations' to 'implement, within the Program activities authorized by this Act, the applicable recommendations,' making the obligation more bounded and limited to existing authorized program activities.

Added a requirement to coordinate with NOAA and FEMA on data sharing and resource allocation for timely response to oceanic earthquakes and tsunamis.

Added citation to a 2023 FEMA/USGS report (FEMA P-366) estimating $14.7 billion in annualized earthquake losses and $107.8 trillion in total national economic exposure.

FISCAL

Reduced annual funding for one program line from $10,590,000 to $8,500,000 for fiscal years 2024 through 2028 (a reduction of approximately 20 percent).

Reduced annual funding for another program line from $100,900,000 to $92,427,000 for fiscal years 2024 through 2028 (a reduction of approximately 8.4 percent), while maintaining the $36,000,000 minimum for Advanced National Seismic System completion.

Reduced annual funding for a third program line from $58,000,000 to $54,000,000 for fiscal years 2024 through 2028 (a reduction of approximately 6.9 percent).

Added a new funding controls section requiring that agency funds may only come from amounts authorized to be appropriated to that agency in advance via appropriations Acts, and that any cancelled appropriations must be transferred to the Treasury general fund for deficit reduction.
