The Northern Chile tsunami was generated by a Mw 7.7 earthquake (22.247°S 69.890°W), 2007-11-14 15:40:50 UTC (according to the USGS).

Animations of the November 14, 2007 Chilean tsunami propagation created with research runs of the MOST tsunami forecast model. The animation was created with a Mw=7.5, 100 Km x 50 Km source inverted from DART® data. Triangles indicate DART® buoy locations. Click the image to animate (left) or enlarge (right).

The animation and graphic display qualitative and quantitative information about the tsunami propagation including tsunami wave interaction with ocean floor bathymetric features, and neighboring coastlines. The tsunami radiation pattern is indicated with color coded information about the maximum wave amplitude at different locations throughout the Pacific Ocean.
