Figure 4 - Depth-dependent rupture mode along the Ecuador-Colombia subduction zone: Depth-dependent rupture mode

Comparison of the slip distribution of the 1906 earthquake with the main shocks and aftershocks of the 1958, 1979, and 2016 earthquakes. The slip areas of the 1906 earthquake are displayed by colored squares with slip magnitudes indicated by the color scale. Red contours represent the slip distribution of the 2016 earthquake. Source mechanisms colored red indicate those of the 2016 earthquake (M w 7.7) and its aftershocks. The pink source mechanism is the Global CMT solution of the 1979 earthquake (M w 8.1), and pink stars indicate the epicenters of the 1979 aftershocks. The source mechanism of the 1958 earthquake (M w 7.7) (green) is assumed to be the same as that of the 1979 earthquake, and green stars indicate the epicenters of the 1958 aftershocks. The epicenters of the 1979 and 1958 earthquakes are those estimated by Mendoza and Dewey [1984] with quality A or B. The black rectangle encloses the high interplate coupling patch (C5) corresponding to the source of the 1958 earthquake.
