Whoops

Sorry about that:

ZURICH, Dec 9 (Reuters) - Swiss engineers halted an experiment to extract geothermal heat from deep below ground after it set off a small earthquake in the nearby city of Basel, the Swiss news agency SDA said on Saturday.

Managers apologised for any fears aroused by the mishap, which occurred after water was injected at high pressure into a five-km-deep (16,000-feet-deep) borehole, but said the experiment posed no danger, SDA reported.

Sure, you say that now. Just because Switzerland is landlocked doesn't man you can't break off a chunk. You know the rule - you break it; you buy it.
