   “2004 December 28, Tom Paulson, "Tsunami warning system being developed in Seattle could avert disasters", Seattle Post-Intelligencer The tsunameter pioneered at the Seattle lab is actually a system — a sophisticated pressure gauge set on the ocean floor that sends signals to a surface buoy.”

   “-2005, "Chilean Tsunameter Project Information", National Oceanic and Atmospheric Administration, National Data Buoy Center, at www.ndbc.noaa.gov http://www.ndbc.noaa.gov/dart/chilean_tsunameter.shtml As part of the National Tsunami Warning System (SNAM) of the Hydrographic and Oceanographic Service of the Chilean Navy (SHOA), the first Tsunameter mooring system has been deployed in the northern region of Chile.”
