A Comparison Between the Previous Source Model and Our Model of the Large Earthquakes Along the Ecua

Caption

(Left) The previous source model of the large earthquakes in this subduction zone. The 1906 earthquake has been interpreted as a megathrust event (Mw 8.8) ruptured all segments of 1942, 1958, and 1979 earthquakes. (Right) Our source model of the large earthquakes in this subduction zone. Our analysis of the 1906 earthquake indicated Mw 8.4 and the occurrence of the large slip near the trench (black triangles with line) off the source areas of the three earthquakes.
