Tsunami Estimated Travel Time

The tsunami travel time layer represents the expected travel time from earthquake epicenter to coastal locations. The contour lines are generated at half-hour intervals. This information uses message received from the Pacific Tsunami Warning Center to run the Tsunami Travel Time (TTT) model to generate the contours.

note: This overlay only shows travel times for a recent event. If there have not been any recent tsunami-generating earthquakes, the overlay will be empty.
