The NOAA National Centers for Environmental Information (NCEI) and the co-located World Data Service (WDS) for Geophysics compile and archive a comprehensive set of tsunami-related products as part of the NOAA Tsunami Program efforts to support the interests and needs of domestic and international tsunami warning centers, engineers, oceanographers, seismologists, and the general public. The archive includes:
Tsunami deposits, in particular, are valuable in that they are often not systemmatically archived, yet they are the physical evidence that remain along coasts and in submarine sediments after tsunami waves have long dissipated. impact. These deposits can be preserved in the geologic record and are often the basis of scientific debate as to storm versus tsunami origin.
Water Level Data that includes1-minute averaged coastal tide gauge data from the NOAA/NOS Center for Operational Oceanographic Products and Services (CO-OPS), as well as higher-resolution water level data from gauges maintained by each of the tsunami warning centers and from secondary storage internal to individual coastal tide gauges.
Access to 1-minute data is provided at CO-OPS site: https://tidesandcurrents.noaa.
The Tsunami Runup database provides specific information on locations at which tsunami impact was recorded or passed down in stories. Measurement types and uncertainty are all provided either quantitatively or qualitatively.
