geothermal cauldrons at bara

 

so hard to call whats happening but if the flow keeps up so does the risk of something larger happening

The Bada caldera GPS has frozen because the relay station has ran out of diesel again I suspect, weather will make a refill difficult.

 

The EQ's keep coming, a 4 then a 5+ just  by the looks of this chart.

 

Looks like a huge one on the Vala chart, but it always does...

 

Webcams at Mila Bada 1 and 2 are snowed over, so we await a visit from a brave superjeep ...

Morning all barbaarians

GPS appears to be working again this morning. Just about maintaining the downtrend from the previous 24Hrs.

Two over M4 EQ's this morning, so still rumbling away.

I have noticed that there seems to be a tendency for more EQ's away from Barda(>10Kms) in the past couple of days. Does this indicate the instability is spreading? Or is the pressure being eased by a smoothing out process?

The Webams are working this morning. Though 2 is very poor visibilty and 1 is covered in snow with just a peephole thru the middle showing a snowy scene in front. Hopefully there will be some melt during the day.

Bardarbunga volcano update: Continuing eruption formed a 70 km² lava flow and caused 44 m of caldera subsidence since its onset on August 31

Sunday Nov 09, 2014 22:48 PM |

The latest map showing the extent of the lava flow as estimated from radar images. The lava now covers 69,9 km² (69,5 km² + 0,4 km²). Analysis by the Institute of Earth Sciences (IES).

Data from the GPS station at the centre of the caldera, showing the temporal transmission defect between 7 and 8 november, and a subsidence of ca. 0.5 m in that time span.

Overview of the vertical displacement measured at the centre of Bárðarbunga caldera since September 12 - total subsidence since then is ca. 21 m.

The volcanic eruption at Holuhraun gives no signs of weakening and continues to eject an impressive lava fountain from the central Baugur crater at a rate similar to the past few weeks. This record-breaking eruption started on the 31st of August 2014 and formed a more than 17 km long lava flow. Using the successive outlines of this lava flow as drawn on a radar image from the Icelandic Coast Guard, researchers from the Institute of Earth Sciences estimated that by now the lava has covered an area of 70 km².

Subsidence of the glacier surface above the Bárðarbunga caldera is also still going on. This vertical displacement is monitored by near real time presentation of data from a GPS station that was mounted in the centre of the caldera on September 11. There was a technical problem that prohibited transmission of these GPS data on the 8th of November, but this has been fixed. Comparison of the vertical location of this GPS station before and after the ca. 24 h communication problem shows subsidence of up to half a meter in a single day. The total subsidence recorded at Bárðarbunga caldera since 12 September is 21 m and based on earlier GPS data the total subsidence since the onset of this eruption is at least 44 m.

The area’s seismic activity is also continuing at a similar intensity. On November 7 there was a M 5.4 earthquake at the northeastern rim of the caldera and this was the first earthquake over magnitude 5 since the 2nd of November. Since then, 15 earthquakes between magnitude 4 and 5 occurred, as well as quite a few between M 3 and M 4. Lower seismic activity is also observed at the intrusion, the largest earth quake of which was of magnitude 2.5.

Nice video, certainly looks impressive, I wonder how high the rift stands now, looks a couple hundred feet!

[Rustynailer]

I am noticing a slight variance of the odd EQ here and there, they are manually checked so they must be real, Ill explain my thoughts on what I think is a possibility...

  Shows EQ's over the last 2 days.

Green star EQ's since year 2000 Jan 1st

 Detail. (note no large EQ's at Grims in 2011...Odd indeed)

 

Looking at the occasional EQ's recently this looks like a possible development direction***. Dike intrusion or even fissure maybe? It could be nothing...

 

Bada is developing and the officials don't know how, we are all learning, quite humbling.

 

Nice to see an outbreak of fresh videos, hope there are more where they came from...

 

*** Direction, not distance, definitely not distance...

 

Can't see Bada on the cameras today, yesterday it was visible until the snow started, mmmm always thought snow was great.... then the snow After that it is white out, read em and weep snow fans. That includes me..tsk....

It was 100m (328 feet) a month ago so will likely be larger now. It's hard to get a feel for the sheer size of the whole area as there's nothing there to reference it against for scale. There was an aerial shot a while back of a 4x4 beside the lava flow: it looked like a dinky toy.

[SteveB]

Really, that's amazing. It must be stunning seeing what might eventually become a mountain growing right in front of you.

[picog]

Is there still tonnes of sulphur coming out of the volcano? If so, is there enough to affect the NH weather?

Edited November 10, 2014 by picog

[The PIT]

Plenty of Gas coming out of the volcano. If the eruption lasts as long as the Laki eruption we may experience similar problems. If it stops tomorrow probably not. It would be interesting how a winter with blocking would bring to the table. Probably the worst case scenario.

Interesting how the quakes around the dike have dropped away indicating a free passage to the eruption site.

Pollution Forecast across Northwest Iceland Tomorrow By Zoë Robert November 10, 2014 12:23 Updated: November 10, 2014 14:56

Sulfur dioxide (SO2) pollution from the eruption in Holuhraun is expected mainly across western Iceland today but at low levels. Tomorrow, the pollution may be felt in many places northwest of the eruption site, according to the latest forecast from the Icelandic Met Office. 

People who feel discomfort are advised to stay indoors, close their windows, turn up the heat and turn off air conditioning. Periods of good air quality should be used to ventilate the house.

The level of SO2 reached close to 1,000 mµ/m3 in the capital area on Saturday night. At levels above 600 mµ/m3 individuals with underlying conditions are likely to experience respiratory symptoms and outdoor activity is advised against. While health effects are unlikely among healthy individuals, heavy outdoor activity is also advised against, according to the Directorate of Health.

Further information can be found in English on the website of the Directorate of Health. 

Go to airquality.is to check the pollution levels in different locations in Iceland at any given time and to vedur.is for two-day pollution forecasts. Although still being developed further, an automatic gas dispersion forecast, including pollution levels, is also available.

SO2 gas is expected to remain west and southwest of the eruption, including West, Southwest and the western parts of South Iceland.

I just love the volcanic sunset! 

 

Also, stunning photos of the eruption with the snow falling!

It is a rather active day today. Even an over M3 in the neighbouring volcano Krustofel (although I probably killed the spelling of the name).
