Likely heatstress fractures.

If a cool object suddenly has a small part heated up the atoms in a localised area will expand pushing out at the cooler parts.

If the medium being suddenly heated is brittle and bad at conducting as the heated area expands it causes a fracture. Brittle and poor at conducting are aspects that sufficiently frozen ice have.

Glass does this too… me and my bros learned this the hard way by using a can of deodorant as a flame thrower on a window on a cold winter night. 5 seconds of flame and we started to hear a crackle.
