Could be several things. If your pool walls are sunk into ground instead of setting on the ground, or pool is at base of a slope in the yard, and sand is washing out from under pool floor, it might just be a spot where heavy rains let water flow under pool wall and floor eroding the sand under the liner.

Usually small pin-holes in the liner won't do much if anything to the sand, but if you get a larger hole in the liner, the water leaking out of the pool could also cause erosion of the sand under the liner.
