They were banging in those steel plates just after New Years. The whole ground, including our building (the blue-windowed one at left in HB's photo) shook alarmingly. It really was probably equivalent to a series of magnitude 5.x seismic events in the local area (I was in Seattle during the 6.1 earthquake of March 2001, do have some experience with such things). We were starting to worry about windows shattering, and the pounding was causing some headaches...
Anyway, nothing happened, all was well, they look like they know what they're doing out there, and it remains an constant interesting/distracting view.
