From: A long source area of the 1906 Colombia–Ecuador earthquake estimated from observed tsunami waveforms
Comparison of the estimated slip distribution with the seismicity around the Colombia–Ecuador subduction zone. The gray contour lines show the bathymetry at 500-m intervals, and red contour lines show the slip distribution at 1-m intervals based on the results of the inverse analysis. The red star indicates the epicenter of the 1906 earthquake based on Chlieh et al. (2014). The blue cross symbols indicate earthquakes of M w 4.0 or higher that occurred from January 31, 1971, to June 30, 2017, as obtained from the Global CMT Catalogue (Dziewonski et al. 1981; Ekström et al. 2012); mechanisms are shown only when M w is greater than 7.0. The blue circles indicate the epicenter locations of the 1942 and 1958 earthquakes (surface magnitudes of 7.9 and 7.8, respectively) based on Mendoza and Dewey (1984). The vectors indicate the assumed rupture length of the major historical earthquakes based on Kelleher (1972) and Kanamori and McNally (1982)
