Quark Soup has a post comparing the spill to Niagara; and notes that the spill would be a cube ~93m on a side.
Checkling the share price (still hovering around 4.10, so neither good news nor bad) I see BP are starting to ask others to pay up for their shares. It will be interesting to see how that goes – through the courts, or quiet settlements?
Misc people complained at me when I previously said Incidentally, misc people have called this spill “unprecendented”. That seems dubious (except in the traditional sense that 11 dead in Cumbria is headline news for days; 11 misc folks dead in road accidents are routinely ignored); it certainly isn’t the largest, see [[Largest oil spills]] – it isn’t even close. While that was true at the time, it isn’t now, and is #2 behind the Lakeview Gusher which was a rather different event in terms of impact.
