Core-Mantle Decoupling vs. Crustal Displacement Theory
ECDO theory distinguishes itself from the "crustal displacement" ideas of Charles Hapgood, Immanuel Velikovsky, and Chan Thomas by proposing decoupling at the core-mantle boundary rather than the crust. While prior researchers relied on intuition regarding striations and flood legends, they lacked a viable geophysical mechanism. A purely crustal shift would result in ubiquitous surface destruction similar to the Grand Canyon, whereas core-mantle decoupling explains the observed geological data without requiring an uninhabitable, shattered landscape.
