The source fault of the 21 December 1954 M6.5 earthquake has remained a puzzle even after 70 years. Seismic evidence and models suggest that the 1954 earthquake occurred on the Cascadia subduction interface. Revisiting pre-digital earthquakes as in this study can increase our understanding of tectonics and hazard.
