Tit for tat. I made an error on the date of the Cascadia tsunami, so here is your
chance to make an error in determining longitude difference.
The difference in longitude between 123E and 73W is (180-73) = 107 + (180-123) = 57.
This means they are 164 degrees separated in longitude.
The statement was that it was nearly antipodal - that it was the nearest seismic
zone to the antipode, and that statement I still maintain.
