The National Ocean and Atmospheric Administration's tsunami travel times map displays the estimated pre-computed tsunami travel times to select coastal locations from any point in the ocean. The tsunami travel times displayed are in hours and were calculated using TTT software.
This map displays estimated pre-computed tsunami travel times to select coastal locations from any point in the ocean. Travel times (in hours), were calculated with TTT Software (P. Wessel, Geoware) using bathymetry derived from the 2 arc-minute ETOPO2 grid.
NCEI offers a variety of information on historic and recent tsunami events, including estimated travel times - times for the wave to travel from the generating source to effected coasts.
Tsunami Travel Time Software. Maps were generated using Tsunami Travel Times (TTT) software developed by Paul Wessel, Geoware. TTT software calculates first-arrival travel times on a grid for a tsunami generated at a given earthquake epicenter or coastal location. The technique to compute travel times is an application of Huygen's Principle.

An interactive Tsunami Map that shows how your local beach could be affected by a Tsunami.
Calculating travel time is one aspect of tsunami planning. Advanced tsunami hydrodynamic models are developed to simulate tsunamis from probable triggering events. These models are used to estimate the run-up height and inland extent of tsunamis, and to develop tsunami inundation maps for emergency management and public awareness.
Tsunami inundation maps show the coastal areas that may be flooded by tsunami waves. Based on tsunami inundation models, these maps are used to create evacuation maps and guide tsunami-related emergency response and land-use planning.
California Tsunami Hazard Area Maps and Data are prepared to assist cities and counties in identifying their tsunami hazard for tsunami response planning. Selecting the map below opens it in a new window where you can explore your area of interest—zoom in, pan, and click (or tap) a coastal location to invoke a pop-up window that provides ...
When a Tsunami Watch is issued, local officials will begin to plan for response and evacuations. You should also begin to prepare by finding out if you are currently in the evacuation zone and begin to contact family and loved ones.
