GPS. http://strokkur.raunvis.hi.is/~sigrun/#VATN Sigrún modified her Vatnajökull GPS page so it now contains the four most pertinent GPSes for Bárdarbunga (rapid ITRF08-detrended to boot!), so just go there daily to get the trend. Currently the trend is with 1 or 2 datapoints, but all four stations concur to a medium sized intrusion into the crust at Bárdarbunga.

- Jón Bragi : I readjusted my webcam into the direction to Bárðarbunga. But as you can see i have some trees there. But when Grimsvötn eruptet 2011 i did have a good view. Check it out http://www.midhus.is ( Dragon remark: This is a private webcam and he deliberately moved it to give us a view. THANK YOU. Please people handle this link with delicacy, It might not be able to handle a whole lot of traffic.)

PLEASE GET THE LATEST NEWS FROM OUR NEW POSTS!
As long as so much happens it is impossible to keep this page up-to-date
The newest plots can also be found in the comments of the posts or in the posts itself.
dfm August 27th.
First view is an hour by hour evolution showing the quakes’ position and magnitude. View is from the south East, with a 10° forward tilt.
Second view is from the top, hour by hour also.
Pay attention around 30” and 1’15” to see the “backward action” of yesterday then a new progression today.
There may even be a tentative sill formation, look @1’15 coordinates -17, 64.8 or on the left of the “g” of “Dyngjujokull”
Magnitude is given by the scale on the bottom of the plot.
Date is given by the quakes’ color, refer to left side of colorbar.
Terrain elevation is given by the right side of the colorbar.
Quake data from IMO, quality 99%, terrain data from NOAA, made on Gnu Octave
by IMO 3D plot from IMO:
Bardabunga Earthquake Animation 16-18/08/2014
the data comes from the “listi” pages Don’t hesitate to play with the definition (up to 1440) or go on YT to see it directly.
There are 2 event by event sequences, with views from the south then from the East. Then there is an horizontal rotation with all the quakes.
Finally there is a vertical rotation and return.
The color of the quakes gives the date as shown on the left of the colorbar. Terrain elevation is given on the right of the colorbar. On the first sequence, the magnitude if the earthquakes is given by the scale on the right of the plot.
Data from IMO and NOAA, made on Gnu Octave.
Bardabunga Earthquake animation 28/07-17/8/2014
data from IMO and NOAA
I used the etopo 1 bedrock data for the terrain.
The first 2 sequences show day to day earthquake animation from 2 different points of vue.
Then there is an horizontal rotation with all the quakes and 2 vertical rotations.
This is a old piece of code, so be indulgent, I’ll try to do something better next time.

Animation by chryphia: This is a 3D plot of the Bárðarbunga earthquake swarm from 25 July to 24 August 2014 (cold to warm) and past seismicity from 1995 to 2014 (green). The data are from the “listi” (99% quality) from http://hraun.vedur.is, the digital elevation model (DEM) is from GMTED2010 (USGS) and the gray layer (a bit ragged, that was part of the problems) shows the Mohorovičić discontinuity according to http://www.seismo.helsinki.fi/mohomap/
Looking back 20 years (which is really no time) it seems like the NE dyke went into previously relatively “quiet” territory whereas the other seismic centers are not new.
