Tropical Girl, they usually go for the slow kill. I don't know if there will be a huge explosion in the Gulf with so much off venting at the pressure points. I suspect the "earthquake" in Canada was an underground explosion. So many witnesses said there was a rumble, then the shaking, then a "Boom!"

AC4512574 - yes, the Dawgs have been right on everything, but I wasn't clear on HOW the salt dome was breached in relation to Macondo. The scenario I described is the only one that makes sense to me. Remember the calls from the crew to family members before the explosion? They knew something was going on, but said they had to get off the rig before they told their family. They never had the chance.
