For each tsunami earthquake region, ship-based bathymetric data have been collated from German (, French (, Japanese ( and US ( research cruises as well as the compilation of data provided by the Global Multi-Resolution Topography (GMRT) synthesis ( The ship-based bathymetric soundings were quality checked and manually edited if necessary. The collated data is displayed on top of the SRTM15+ grid ( For the New Zealand margin the collated data is displayed on top of the nationwide bathymetric compilation provided by The National Institute of Water and Atmospheric Research (NIWA) (
