Where exactly is Cantha?

The continent of Cantha seems to be a bit randomly placed, seeing as how Tyria and Elona are the same continent/landmass and Eye of the North will also be taking place in the same region. I was just wondering where Cantha is in perspective to Tyria and Elona and why A-Net decided to place it seemingly far away from everything else.

If you read the lore, you would know that its far south of Tyria.
