 The data suggest that the earthquake was probably along the subduction interface.Modelling of a tsunami using these source parameters shows that this earthquake was the origin of the transpacific tsunamis recorded that same day in Hawaii and Japan, rather than the almost contemporaneous 1906 Aleutian Islands earthquake.The 30-minute time gap between the Aleutian and Chilean earthquakes is thought to be coincidental, with no causal link between the two.
