A major earthquake with a moment magnitude of 7.3 (USGS magnitude) occurred at 124613 UTC 9 April 2008 (day 100) and was located 70 km SW of Isangel, Tanna, Vanuatu (20.058�S, 168.858�E, 35 km depth - USGS location).

The earthquake produced a tsunami that was recorded at the Port Vila, Vanuatu tide gage monitored at the Tsunami Warning Centers. The data was provided by the National Tidal Facility in Australia. Click on the site name to see a graph of the tsunami. Listed wave heights are maximum amplitude in cm (above sea level). Observed Arrival time is the actual tsunami arrival time in UTC on gages where it could be determined. The Computed Arrival time is the estimated time of arrival computed at the West Coast/Alaska Tsunami Warning Center (WC/ATWC) based on the origin time and location. The Sample Interval column shows the time between samples.
