Yes. If you have a high water table, then water pressure will try to lift the pool out of the ground. Mostly this is going to be due to water (ground settling could also do damage), so it's less of a concern if you're in a flat, dry area, but even in that case it's still a possibility.
It's unlikely your pool has so much structural integrity that it would literally pop out of the ground. Much more likely is that it would crack or buckle from a lack of pressure equilibrium.
Fill it back up?
However long it takes until you have drained the pool and disinfected everything, filled it back up and tested the water.

The pool has popped out of the ground because it was was forced up by ground water. If a pool is left empty ground water can build up underneath it causing the pool to start to float, Whenever a pool is drained a way of getting rid of ground water has to be set up otherwise there is the risk of this happening.
