The Global Historical Tsunami Database that includes information on tsunami events from 2000 B.C. to the present in the Atlantic, Indian, and Pacific Oceans; and the Mediterranean and Caribbean Seas. Event location, societal and geologic impact along with tsunami deposits and Proxies for Tsunami Eventsare are provided to the extent that information is available.

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.gov/

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.
