§3205 Tsunami research program

Title 33 › Chapter CHAPTER 45— - TSUNAMI WARNING AND EDUCATION › § 3205

Last updated Apr 6, 2026|Official source

Summary

The Administrator must run a tsunami research program with help from federal, state, tribal, and territorial governments, universities, and the law’s coordinating groups. The program will improve science and technology for finding tsunamis, making forecasts, sharing warnings, reducing harm, and making standards. The program must look at cost‑effective ways to cut tsunami damage, such as better near‑ and far‑field detection, a new generation of the DART (Deep‑ocean Assessment and Reporting of Tsunamis) array, sensors on telecom cables, real‑time monitoring, and using the Administration’s supercomputers for fast forecasts. It must work with the National Weather Service, study community warnings and evacuations, validate maps and models, and share results with the public and scientists.

(a)The Administrator shall, in consultation with such other Federal agencies, State, tribal, and territorial governments, and academic institutions as the Administrator considers appropriate, the coordinating committee under section 3204(d) 11 So in original. Probably should read “section 3204(b)”. of this title, and the panel under section 3206a(a) of this title, support or maintain a tsunami research program to develop detection, forecast, communication, and mitigation science and technology, including advanced sensing techniques, information and communication technology, data collection, analysis, assessment for tsunami tracking and numerical forecast modeling, and standards development.
(b)The research program supported or maintained under subsection (a) shall—
(1)consider other appropriate and cost effective solutions to mitigate the impact of tsunami, including the improvement of near-field and distant tsunami detection and forecasting capabilities, which may include use of a new generation of the Deep-ocean Assessment and Reporting of Tsunamis array, integration of tsunami sensors into commercial and Federal telecommunications cables, and other real-time tsunami monitoring systems and supercomputer capacity of the Administration to develop a rapid tsunami forecast for all United States coastlines;
(2)coordinate with the National Weather Service on technology to be transferred to operations;
(3)conduct social science research to develop and assess community warning, education, and evacuation materials;
(4)develop the technical basis for validation of tsunami maps, numerical tsunami models, digital elevation models, and forecasts; and
(5)ensure that research and findings are available to the public and the scientific community.
