National Tsunami Warning Center, NOAA/NWS

TSUNAMI of 16 September, 2015 (Off the coast of central Chile)

A great earthquake with a moment magnitude of 8.3 (USGS magnitude) occurred at 22:54:33.20 GMT on September 16, 2015 (day 259) and was located 105 mi/169 km N of Valparaiso, Chile, (31.570 S, 71.654 W, 15.5 mi/24.9 km depth--USGS location).

This earthquake caused a tsunami that was recorded at tide gages monitored by the National Tsunami Warning Center (NTWC). Many observatories provide data to the Center; such as the NOAA National Ocean Service, the U. of Hawaii Sea Level Center, the Chilean Navy, the Japan Meteorological Agency 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 GMT on gages where it could be determined. The Computed Arrival time is the estimated time of wave arrival computed at the NTWC based on the earthquake origin time and location. The Sample Interval column shows the time between data samples.

For additional information about this tsunami event see the Pacific Tsunami Warning Center's homepage.
