The 1906 EcuadorâColombia earthquake occurred at 15:36 UTC on January 31, off the coast of Ecuador, near Esmeraldas.The earthquake had a moment magnitude of 8.8 and triggered a destructive tsunami that caused at least 500 casualties on the coast of Colombia.ecause the sequence of three earthquakes that ended in 1979 did not release as much energy as the 1906 event, it has been suggested that an earthquake of similar magnitude to that in 1906 was likely in the near future.
