Don't know your particular situation, but it is probably not dirt giving way. Simply, the sand smashing away from jumping in and hitting floor with heels and etc. I had a neighbor that had the same problem. When I got ready to install my pool, I was going to do everything I could to prevent it. I placed sand under the pool and packed it as tight as possible (wet). Used two layers of fan-fold insulating board (used behind vinyl siding 1/4" to 3/8" thick) and taped every seam. Placed liner and filled with water, worked great! Pool floor is still smooth! The pool has been in for seven years and no problems yet! You may also have a problem with moles, believe it or not, and about the only way to get rid of them is to get rid of the Grub Worms and etc.
Rocks with small crystals form above ground, because when formed under ground the magma makes the rock cool slower causing more time for the crystals to grow. Above ground the rock cools faster, because the air isn't as hot under ground than above ground.
