I wonder if this kind of issue will have been taken into account for the new building being put up there.
I once felt a similar thing at a football game. I was sitting in the top row of a stand, and when my team scored everyone jumped up and down a lot (it doesn't happen very often) and the whole stand began swaying around. The amazing thing is that stands at football grounds in the UK cannot be more then 30 degrees steep, so its surprising that the thing was swaying around so much.
