I'm not surprised in a way- after all Cologne is very largely built on the remains of Cologne, with not very stable soil and on a geological fault. Having seen with my own eyes what is under the Dom (namely the remains of a Romanesque cathedral, and several roman houses including intact hypocausts) I would surmise that something has given way.
