It is believed that a small subglacial lava-eruption has begun under the Dyngjujökull glacier. The aviation color code for the Bárðarbunga volcano has been changed from orange to red. Image follows.

Today’s addition to the Bardarbunga renovation:

It’s only about 10 km long and headed directly for another caldera, full of water, that has also been showing signs of pre eruption re-awakening, for the past five years. It probably just wants to say hi.
Hi KaBOOOM I am Lava fountain!
Hi Lava Fountain, would you like a steam explosion?

What will happen next and will people be able to fly on Wednesday and the eruption will only come out if the ice melts

“The more it does this the more dangerous it becomes. The caldera it is now building in the direction of erupted in 1875 and that eruption lead to a mass exodus of people from Iceland. ”
Yep… Global Cooling
This is so cool to watch. Apparently there are signs that the volcano is subsiding (aka sinking) due to extrusion of material away from the caldera northward into the dyke. It’s an explosion all right, but more like a good BM than projectile throw up. Such a baby.

d*ke
lol!!!
USGS shows another 5.3 tremor 108km WNW of Hofn, Iceland 2014-08-24 16:39:13 UTC-04:00 (i.e. 2039Z) at 6.0 km depth
Us old honkers need to relieve some pressure too. lol

I love to go a-wandering,
Along the mountain track,
And as I go, I love to sing,
My lava on my back.
Calderi, Caldera,
Calderi,
Caldera ha ha ha ha ha
Calderi, Caldera,
My lava on my back…
(sorry….)
Ed, amen!
Swarm of 2+ quakes!!!

We have another volcano waking up????
Trölladyngju has been movin and shakin the past few minutes.
One of my comments is still in moderation after an hour. Most likely due to my farmgirl way of talking. And here I thought it would be fine.
I can’t find a reference to Trölladyngju anywhere have you got a link or a lat/lon for it?
Kistufelli at 0 km down 2+ mag 30 minutes ago. As in right on the surface.
Larry, it is on the continually updated list of quakes. You can scroll through the last 48 hours of quakes in the area.

It seems to me that the earthquakes are tending stronger over time. Which seems to me to be an indication of increasing pressure and stress that when released, results in a bigger tremor.

Interesting read on the volcano and its potential.

The pattern has obviously changed in the last 30 hours or so, not sure if that is an important indicator of a basic change in what is going on. As you mentioned it could be just changes in the pressures and flow. As I mentioned above, as the flow continues is should open up the channel of flow by surface melting of the path and clean up rough edges that resist the flow. If true the longer this goes on the capable it is of large flows of lava.
The key as far as any sort of climate impact (if it erupts) will be it’s interaction with the ice. Basaltic lavas in general don’t create large ash clouds that would go into the stratosphere (like andesitic volcanoes can do). The basaltic lava has to interact with the ice to create phreatic explosions to accomplish the same thing. Looking at the maps of EQ activity & the position of the activity wrt to the edge of the ice, it would appear there is a chance it could go either way – either under the ice or outside of the ice …. time will tell.
As a geologist, this is fascinating to follow as it develops. Thanks for all the commenters with current activity links . Keep it coming !
Hopefully the dyke will not extend further north and reach Askja as some people are suggesting on here.
If that goes with any considerable force the Europe may be facing a harsh volcanic winter. The last time there was a major eruption at Askja in 1875 snow fell in the UK until may the following year.
“1875-76: Amazingly snowy winter for the UK, especially the South East early on, the first week of December dumped 1-2ft in some places, worst in the South East. March of this month had many snowstorms, and April recorded nearly 2ft of snow in the Midlands! Snowfall was recorded (on a notable scale), in November, December, January, February, March, April, and May! I would regard this winter as very snowy.”
The maps suggest that the dyke is still forcing its way north, we could do with Bárðarbunga blowing and relieving some of the pressure.

“The last time there was a major eruption at Askja in 1875 snow fell in the UK until may the following year.”
I remember snow in May in the UK back in the late 80s or early 90s. 1980s or 1990s, that is.

You can see how they are propagating north with time but also see how they are not moving towards the surface with time.
“I remember snow in May in the UK back in the late 80s or early 90s. 1980s or 1990s, that is.”
Thanks for your input i will make sure your assessment is sent off to be recorded in the history of British winters!
Interestingly the central England temperature record shows that the average annual temperature in 10 years prior to the 1875 eruption averages at 9.42C whereas the 10 years post eruption average 8.99C so there could be a decade of effects on European temperatures from a similar eruption.

I would agree Jeff, except Laki 1783 was not in the ice belt, though certainly many phreatic explosions would have still been produced. Allegedly the peak of the lava fountains rose to 4,600 feet above ground level (what a sight that would be), and the haze went right around the world to low level, and the entire sequence lasted two years, including the eruption thereafter of Grimsvotn, just up the hill, on top of it all (isn’t it interesting how the higher terrain erupted last, the magma did not just flow down to feed the still smoking connected fissure complex).
So you don’t need ice involved to get the global cooling, you just need a huge volume of magma. It doesn’t seem to matter how it erupts for global effects when theirs enough of it coming out. Volume is more the danger than the style it seems. As the explosive phases are short.
I note also that the 1783 eruption was not associated with the bright salmon pink afterglow sunsets for years after, as far as I am aware, so little high SO2 to altitude, or so it seems – but it cooled the earth anyway.
