The earthquake produced a tsunami that was recorded at Port Vila, Vanuatu and at Honiara, in the
Solomon Islands (both stations operated by the National Tidal Facility of the Flinders University of
South Australia). Wave heights are maximum peak-to-trough height in cm. Arrival
time is the actual tsunami arrival time in UTC on gages where it could be determined.
The ETA is the estimated time of arrival computed at the National
Tsunami Warning Center (NTWC) based on the origin time and location. The Sample Interval
column shows the time between samples. Click on the Data File column to get the
