Solomon Islands Tsunami of 05 January, 2010

Two earthquakes occurred on January 5, 2010 near the Solomon Islands in the southwest Pacific. The first earthquake, magnitude 6.8 at 12:15:32UTC, was located at 9.056S, 157.585E and the second earthquake, magnitude 6.9 at 12:15:36UTC, was located at 8.886S, 157.522E (USGS parameters). One or both events triggered a tsunami, however, due to the close origin time and location of the sources as well as the small amplitude of the observed wave, it is not possible to distinguish between the events. The computed travel time is provided for the first earthquake.

The tsunami was recorded at tide gages monitored at the Tsunami Warning Centers. Many observatories provide data to the centers; such as the NOAA National Ocean Service, the U. of Hawaii Sea Level Center, the Chilean Navy, and the National Tidal Facility in Australia among others. Click on the site name to see a graph of the tsunami, when available. 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 National Tsunami Warning Center (NTWC) based on the origin time and location. The Sample Interval column shows the time between samples.
