A large earthquake with a moment magnitude of 7.7 (USGS magnitude) occurred at 1541 UTC 14 November 2007 (day 318).The earthquake was located 25 miles/40 km ESE of Tocopilla, Chile (22.2°S, 69.8°W, 25 miles/40 km depth – USGS location).


The earthquake produced a tsunami that was recorded at tide gages monitored at the Tsunami Warning Centers (the tide sites are operated by the Chilean Navy and the National Ocean Service). Click on the site name to see a graph of the tsunami. 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.

For additional information about this tsunami see the NOAA/Pacific Marine Environmental Lab web site .
