WI: Another Great Kanto earthquake--in 1941

I'm not sure if geological phenomena belong in ASB or not, but the idea occurred to me when thinking of more alternative WWII scenarios. If a 9.5er hit Kanto before Pearl Harbor, what effect would it have on the Pacific War, the Empire, Europe, hell, the post-war world?

It is just like WI Mount St. Helens 1990 eruption happened one day later, or one day earlier, or did not happen at all, or WI Hurricane Sandy had been stronger or weaker; geological phenomena is not really ASB. A minor POD might cause butterflies to change the pressure and velocity of the plates enough to cause an earthquake.
