The most common causes of subsidence are as follows: 1. Settlement of old mine workings, often at great depth, resulting in damage to structures on the surface. These may often be a long way from the cause of the damage. Access shafts are notoriously difficult to identify as mine operators rarely kept good records of these points. 2. Damage to subsoils caused by water flowing through them. This may be from naturally occurring ground water or leaking drains and water mains.
Subsidence Inversions Take pace in valleys or in places partially surrounded by hills or mountains. When the air blows over the hills, it is heated as it is compressed into the side of the hills. When that warm air comes over the top, it is warmer than the cooler air of the valley. Also, increasing the inversion, as the air comes over the top of the hill, it causes the air in the valley to be compressed, heating the cooler, valley air from the top down. When this cool air is trapped and compressed, so is everything that is in the air, such as vehicle emissions, smoke, and smog in general.
