National Tsunami Warning Center, NOAA/NWS

Offshore Maule, Chile Tsunami of 27 February 2010

A great earthquake with a moment magnitude of 8.8 (USGS magnitude) occurred at 06:34:14 UTC 27 February 2010 (day 058) and was located 60 miles/100 km NNW of Chillan, Chile (35.846S, 72.719W, 21.75mi/35.0km depth--USGS location).

This 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 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 based on the origin time and location (Note: The computed arrival times are those determined during the event based on a point source (the epicenter) which produces significant error in the near field due to the extended nature of the rupture). The Sample Interval column shows the time between samples.

For additional information about these tsunami events see the Pacific Tsunami Warning Center's homepage .
