The webcams are once again looking very impressive tonight with the miles long river of lava glowing brightly.

Some odd movements in the GPS data in the caldera last night. After some steady falls, the level rose by a metre very quickly, before subsiding again.

I think the graphs show various averages, but the movement is still evident.

5.2 on the northern rim of the caldera a few hours ago, followed by a 4.8 on the southern rim.
5.2 this morning on the northern rim again. Perhaps we should start to worry if we start seeing large quakes in the south but so far this hasnt happened
Anyone knows why theree aren't updates in the caldeira subsidience graphics?

New video taken yesterday (16th) shows the lava flow is still very strong.

Earthquakes have been fewer recently, but the caldera drop is still ongoing and averaging a bit above 40cms per day, this makes the total so far to around 37m.

It just goes to show the power involved in these quakes. Incidentally this latest quake in the caldera followed a magnitude 4.7 just two minutes earlier.
Are we starting to see some harmonic tremors? If so, it could be the start of something really big. According to latest estimates if Bardarbunga errupts and causes a jökulhlaup it will release up to 25,000 cubic meters of water per second. Link - The text is in Icelandic, but Google translates it as:
"The IMO assumes the possible floods in the mountains Jökulsá could amount to 25 thousand cubic meters per second. According to a new preliminary assessment of flooding if the eruption Bárðarbunga causing glacier run. The flood would reach the blowout lava within half an hour, we go Upptyppingar two hours and went past the mountain after three and a half hours."
