This note is intended to provide the basic information required to model the 21st April 2007 tsunami generated by a series of landslides in Puerto Aysén, Chile. The landslides were triggered by a 6.2 earthquake following 2 months of intense seismic activity in Aysén fiord. The earthquake occurred at 13:53 (local time) and, as a consequence of the tsunami10 people died, salmon cages were destroyed and houses in the fiord’s coastline were washed away.
My opinion is that this information will be of great interest as this landslide event is probably oneof the most well documented landslides tsunamis in history, as high quality bathymetric data,run-up records and even a tide gage record are available for its characterization. There is alsocomplementary information in the form of photographs and videos which may be helpful tointerpret the results.
