Thank you both. 
I'll check the links in a mo.
I'm very addicted to bardarbunga and have been following this thread pretty much since it started and Jon fr's blog for about the same amount of time. Not sure if that makes me sad! Lol!
Nannynick, was what you saw last night confirmed anywhere? I've not looked at the Jon fr blog yet, but will do in a mo. Is the wall you mentioned, the newly built up bit around the erupting fissure?
Quick question for you, is the lava that's spewing out at the moment, taking ac?ount of what's entering the system from below? There's a lot of mention on the other site about this, but I,m not sure I understand it.
Also, if all this stuff is coming up from many km's way underground, is this creating a cavern down there, which could collapse? If 1cubic km of 'stuff' has come out, what's taking it's place deep down?
Sorry if that's a nonsensical question. My head is full of those. :)
