Hi, group

Here's a fun page -
http://www.npagroup.co.uk/insar/products/pdf/psi.pdf It shows
satellite interferometry measurements of the centre of London, with
9mm of subsidence caused by the JLE very clearly shown. Nothing scary
- all planned for, it says - but very interesting.

But what's going on between Wandsworth and Battersea or, for that
matter, 2km due north of Westminster?
