Tsunami Travel Time Software

The World Data Service for Geophysics (WDS-Geophysics), co-located at the NOAA National Centers for Environmental Information (NCEI, formerly National Geophysical Data Center NGDC), serves as the world’s recognized tsunami database and archiving centre. The WDSGeophysics and the ITIC are providing free-of-charge, tsunami travel time calculation and display software to government organizations involved in providing tsunami warning and mitigation services. Other interested organizations and individuals are requested to obtain the software directly from the developer, Geoware. The Tsunami Travel Time (TTT) software is used by the PTWC for its operations calculations, such as in Tide Tool. Map graphics are made using the open-source Generic Mapping Tools (GMT). Available since 2007.
