This dataset consist of a series of Tsunami Travel Time maps showing the expected travel time of the first arrival of a tsunami from a particular location to the closest point on the coast, a coastal tide gauge station or a DART location. The maps were created with ttt (https://www.ngdc.noaa.gov/hazard/tsu_travel_time.shtml). The travel times are contoured every half hour. Note that the amplitude of the wave is not calculated, nor does it show the arrival time of the first maximum or the overall maximum of the tsunami. They would be expected to arrive later than the times shown. Note also that the accuracy of the model is limited by the accuracy and resolution of the underlying bathymetry data which is relatively coarse near the coast.

New Zealand network of tsunameters in the southwest Pacific. Tsunameters, devices or systems that detect tsunamis, often use Deep-ocean Assessment and Reporting of Tsunami (DART) real-time monitoring systems. Information about the DART network can be found here: https://www.geonet.org.nz/tsunami/dart Sensor and instrument metadata can be found at https://github.com/GeoNet/delta/blob/main/network/sites.csv DART Raw and Detided data is available via the Tilde API (https://tilde.geonet.org.nz/v3/api-docs/), the Tilde UI (https://tilde.geonet.org.nz/ui/data-exploration#/) and for data-tutorials see (https://github.com/GeoNet/data-tutorials/tree/main/Tilde). The detided constituents are generated by NIWA and can be found here: https://github.com/GeoNet/delta/blob/main/environment/constituents.csv. DART BPR data. The BPR records are available in Tilde (using "Method=raw"). This also includes Temperature (water-temperature) and Pressure (water-pressure) data. DART Trigger Catalogue. A catalogue of all of the auto-triggers on the DART network can also be found here: https://github.com/GeoNet/data/tree/main/dart-triggers DOI for DART Dataset: https://doi.org/10.21420/8TCZ-TV02 DOI for DART Network: https://doi.org/10.1029/2020EO144274 Cite Dataset as: GNS Science (2020).
