I must say,it's hard to think there isn't a danger of the capstone sliding off when you see this picture from 11 years ago http://www.themodernantiquarian.com/site/11/trethevy_quoit.html#images
(the last one in the last line but one, posted by phil).
I can only presume the EH engineers have calculated that friction will keep it in place.

So far as the other movement is concerned, have you been able to replicate any of the early pictures on TMA in order to show a change?

A word of caution - a desk based assessment of historic images by people that actually knew the Avebury stones very well suggested the Cove stones might fall, but when they spent a packet on engineering kit and scaffolding and excavated below, the stone giving rise to concern was found to be roughly 7x4.5x1.5m with 3m of it under the ground and estimated at 100 tonnes - one of the largest in Britain and it wasn’t likely going anywhere…
