To help add some information to the OP
On June 23, 1946, Vancouver was struck with a 7.3
"This earthquake is Canada's largest historic onshore earthquake"
Interestingly enough, On April 1st, Hawaii was struck with a 14- metre high Tsunami, killing hundreds and injuring thousands.
Tsunami's are caused by displacement of water, meaning either an earthquake or volcano went off in the pacific
If a 9.0 causes little effect on Hawaii today, then who knows what caused a 14 meter wave. I will research if it reached Japan
Interestingly enough as well, the U.S detonated the first nuclear bomb in 1946 in the Pacific Ocean
August 4th, 1946- 8.0 Dominican Republic, killing 100, 20 000 homeless
Nov 10th, 1946- 7.4 Peru, 1400 killed
