Just to come back to this point Dave. It appears that it is indeed more than just a perception due to light levels and is apparently due to increasing activity in the evenings so far. The magma that is erupting also appears to be coming directly from the mantle and not from magma chambers in the crust. Overall activity does not seem to be decreasing and may in fact be increasing (which ties in well with some of the livestream footage).

Go team me

I was reading quite a few of the articles from the Volcano Cafe you linked to the other day, which were really fascinating. Seems like if the dyke isn't being topped up the eruption may gradually dwindle over a period of a couple of weeks, maybe a bit more but if it is being topped up still it could last considerably longer. So could be either an interesting but in the scheme of things pretty small eruption or something more impressive/noteworthy. I'd hope for the latter, particularly as it currently looks like there still wouldn't be any issues with settlements etc.

Was watching the feed on and off today and the larger cone had a chunk of the rim fall off earlier (about 4ish I think it was) but as it was above the lava level it didn't do anything. Does show how unstable the cones are though and something more interesting may occur and lead to a short term large increase in flow.

Quite a bit of collapsing went on in the Icelandic volcano early up this morning, with the 2nd cone losing a lot of material from the front and side and a chunk going from the front of the main/original cone. (As viewed on the RUV feed anyway other perspectives may differ!).

Bit hard to tell but it looks like that may have at least temporarily stopped the flow from the 2nd cone. (The webcam from that side doesn't look like it's working ATM). 

One of the things I was watching yesterday mentioned 18 days as the likely time it'd take to break out from the valley it's in, presumably based on a fairly steady outflow. So another 10 days or so, if things continue. 

I suspect that the flow is continuing apace but just not visible from the camera angle (and possibly under lava pool’s surface).

Someone's having a play with the camera at the moment and yup, the second cone is still flowing. It's hard to tell from a distance as the outflow is so low down compared to where it was it's all under the skin on the surface of the stream.  

May have been posted already if so apologies but I thought this drone footage was remarkable..

A drone pilot has captured incredible footage of a volcano erupting in Iceland.

Bjorn Steinbekk risked losing his FPV drone as he flew the camera directly over the lava as it continued to shoot and spill from the Fagradalsfjall volcano near Iceland's capital, Reykjavik. pic.twitter.com/Uo3swR3q63

Is that a new vent that's opened. Also fountains look a little higher.

I think it looks a bit different because of the collapse of the front walls of the vents. The lava lake is filling up nicely and I think it is probably only a matter of time before it starts flowing into the neighbouring valley.

I'm guessing that great big chunk of rock floating in the lake is the part that collapsed? Yes all looking rather level/full now.

Yes, I think so. It looks quite impressive from this camera angle: https://www.mbl.is/frettir/innlent/2021/03/29/gosid_i_beinni/ 

There's still a lot of activity tonight with both the main and the lower vents churning away and pushing out significant streams of lava.

It really is a remarkable sight at night.

A few days into the eruption the BBC was reporting that the authorities had said the activity was easing off but it certainly appears not to my untrained eye.
