NOAAs Tsunami Data Archive

• NOAA has primary responsibility for providing
  tsunami warnings to the Nation, and has a
  leadership role in tsunami observations and
  research.
• The National Geophysical Data Center (NGDC)
  provides the long-term archive, data management,
  and access to national and global tsunami data
  for research and mitigation of tsunami hazards.
• Archive responsibilities include global historic
  tsunami event data, bottom pressure recorder
  data, event-specific tide-gauge data,
  publications, photos showing damage from
  tsunamis, as well as other related hazards data
  and information.
• The overall purpose is to scan any analog data
  that may contribute to the enhancement of NOAAs
  Tsunami Forecast and Warning capability as called
  for under Public Law 109-424, The Tsunami Warning
  and Education Act, and its Global Historical
  Tsunami Database.
