Slightly irritating ads in the middle/end but another good wander around the eruption site including the earth walls they've built to try and stop it overflowing in to the next valley and towards a main road (and over some buried cabling). The sound from the eruption is pretty cool too - a lot of vids you don't really hear that due to the noise of the wind.

Interesting that the average flow is up to 13 cubic metres a second at the moment (was 5-8) - certainly not showing any signs of finishing soon. 

You can also see just how deep the lava is getting by looking at the original vent and area around that - when you think the original vent was at the end of a ridge, which is now buried it just shows how deep it is at that point. 

This RUV webcam shows the wall/dam to the bottom left of the streaming image:

Seems to be becoming more like Puʻu ʻŌʻō, perhaps fed from Grimsvotn plume rather than just Mid-Atlantic rift.

Thankfully Goma was spared from this latest eruption but sadly a number of people have been killed in surrounding villages.

Meanwhile at the less harmful end of the scale things are still going steadily in Iceland

I saw that - I did wonder if it crashed or was destroyed in flight?

I got the impression it was deliberately sacrificed, Peter - but don't quote me! Certainly looked realistic to me!

I think it might make it to the sea..
There seems to be a more steady flow now, rather than eruptive?.

I suspect it will if it lasts long enough although it's not making much headway through the valley at the moment, just getting deeper where the 2 feeds are flowing in.

Watching the live cams and play backs, I've noticed that the lava tends to roll down into the valley in short, aggressive bursts rather than just a continuous stream like manner, almost as if has to 'build up' first on the plateau before it unleashes itself.

What I don't understand is how the lava can stay so hot and red after so many days exiting the volcano, even in those cool/cold Icelandic winds. Clearly I don't know anything about how lava works but it is just fascinating to me how it can retain such incredible heat for so long after being exposed to the open air.

It is fascinating and I think, to answer your question, the lava is insulated to a large extent by the solidifying stuff above it and then it largely flow underneath it in tubes or rivers only breaking out in red hot form when it gets moved to the surface at the edges or steep gradients.

Makes sense! 

Really incredible how 'insidious' this lava flow is. Rarely do you see it move forth (even in time lapse footage) yet very surely, it is creeping ever so slowly forward to destroy all in its path.

Footage from the edge of the lava flow in the valley today. (a good channel to follow for near daily close up footage)

Has cooled down some but still some hot spots to be found.
