Column 4 indicates on which sheet, if any, of the British Geological Survey's 1:50,000 / 1" scale geological map series of England and Wales, the fault is shown and named (either on map/s or cross-section/s or both). A handful of BGS maps at other scales are listed too.
Subsidence frequently causes major problems in karst terrains, where dissolution of limestone by fluid flow in the subsurface creates voids (i.e., caves).If the roof of a void becomes too weak, it can collapse and the overlying rock and earth will fall into the space, causing subsidence at the surface.
Mine subsidence coverage may vary depending on what state you reside in and the insurance company writing your policy. In general, the coverage includes a deductible, but offers coverage up to a ...

The geology of England is mainly sedimentary. The youngest rocks are in the south east around London , progressing in age in a north westerly direction. [ 1 ] The Tees–Exe line marks the division between younger, softer and low-lying rocks in the south east and the generally older and harder rocks of the north and west which give rise to ...
