This thread linked on that page is of interest. Apparently this comet is splitting into fragments, but I briefly scanned the article and didn't see an Earth fly by date.

Does it matter that comets are largely made up of ice and loss debris. What does a ice-ball plus a fireball in the atmosphere equal, gas and water vapor and some, mostly loss, debris. The amount of energy released equals weight times speed. How much does frozen water and gas weight compared to rock? Given that comet, or rock, will either have around the same speed, or the comet much less as it fans out in the atmosphere, and that every time you halve the speed the energy is going to be 4 times less. So a hit might have little chance of actually causing a catastrophic failure in the volcanic region by the time the energy gets to the see floor, unless the sea floor is very fragile (I'm taken that the strike is supposed to be on water) which means such a catastrophe was likely to happen anyway, with or without a meteor, unless the build up or energy was due to rise and settle down before reaching near the pinnacle of volcanic cascade.
I'm winging it here, but from my little knowledge that seems to be it. So yes, if it happens and doesn't strike in in a big pile, it will still be dangerous from the bits of debris, the ones that don't get burned up in the atmosphere.
