There is an underground patch at home that will emit white smoke after it rains and the sky is clear. How to explain this in Feng Shui?

There is a patch of ground at home that will emit white smoke when it rains after it rains. How do you explain it in Feng Shui? This is a normal geological phenomenon. The ground contains a layer of material similar to lime. After rainwater infiltrates, lime will expand to produce gas and heat, producing water vapor. Some of this material is the coal ash layer left after ancient coal seams were burned. Some of the limestone fell to the ground and was burned into lime by geothermal magma. It was buried deep underground. Then it was lifted to the surface of the earth due to geological movements. It vaporized when it encountered rainwater and white mist appeared.
