Tsunami of 1 April 2007

A great earthquake with a moment magnitude of 8.0 (USGS magnitude) occurred at 2040 UTC 1 April 2007 (day 091) and was located near the Solomon Islands (8.453S, 156.937E, 10.0km depth - USGS location).

The earthquake produced a tsunami that 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 Japanese Meteorological Agency, 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.
