At what depth is R'lyeh located?

According to the coordinates given by Lovecraft (47°09′S 126°43′W) it is located near the pole of oceanic inaccessibility (Point Nemo).

Doing some research, the ocean floor in that area appears to be -3977m (13048 feet).

Has R'lyeh therefore sunk to the ocean floor? Does Lovecraft ever give any indication of the depth at which it is located?
