silence for the storm on bardar caldera now??????

nooo.... its picking up again... gravity of the full moon stabalised it for an coupple of houers i suppose...?a reply to: ressiv

not sure where you get that from ressiv, the numbers are down 24.4% for the last 24 hours, only 64 earthquakes
energy released is steady, yesterdays 5.5 threw that TTNT ER up for that day.
The graph up above has been updated, for comparison purposes here
map and timeline graph for the 8th

Scientists from the Icelandic Met Office and the Institute of Earth Sciences and representatives of the Civil Protection in Iceland say;
The eruption continues at a similar intensity as previous days.
The subsidence of the Bardarbunga caldera continues with similar rate.
Very little seismic activity is now detected in the northern part of the dyke and around the eruption site.

if this is what you were reading, remember it is about the day before, i.e the 7th, even though it is published on the 8th.

The main crater Baugur has reached a hight of 100 meters, Suðri is 50 meters high, the lava field has grown as large as 53km2.

How appropriate, there was a proposal to adopt the name 'Nornahraun' (the witches lava) for the new lava flow field in front of Dyngjujökull, and the vent system 'the nornir cone row'.

This of course because of Pele's hair, witches hair.

This is interesting, swarm in Herðubreið (lit. broad-shouldered) volcano, northeast of Askja. There was swarms during the early activity of Bardarbunga, but it has been quiet since then. Herðubreið is part of Askja system, but its status is unknown. It hasn't erupted during the holocene, but shows some geothermal activity and minor swarms.

hmm obviously you don't read my daily blog posts on volcanic tremors
Herdubreid (the northern cone) and Herdubreidartogl have featured every day since the start (12.08.2014)

further to: muzzy
actually the swarm you refer to is 6km N of Herdubreid

about Yellowstone update

well I guess I can't depend on ATS members to proof read my work for errors

made a big mistake with the times on the earthquake events for the whole year!
everything is timed 00:xx:xx (hh:mm:ss) rather than the hour it sould be, I must have set something up wrong.the loctions and the date are correct though.
I only just noticed when looking at the graphs, the events seemed to line up evenly every day WTF???
then I went back and looked at the actual Excel files and sure enough ......... hour column was wrong

So YS2014 is on hold, you won't be able to read it until I get it fixed.

that's the trouble with doing batch archiving of multiple months at a time, if one is wrong, they all are wrong

arrrrrrrrrrggggghhhhhh

and I was just cruising through doing 1985 too, ready to post the monthly maps and graphs. Luckily they are OK hour wise!

update to: muzzy
OK fixed that
The graphs still look a bit spaced, especially August, but that's the way Yellowstone works it seems, the times are corrected.
YS2014
New Feature
I found a KML file from YVO of the outline of the Caldera (present day) so chucked that on the 2014 files, I''ll go put it on the other maps too now.

1985 nearly done.
I suppose I could put these over on What's going on at Yellowstone part 2 but I haven't read the whole 768 pages of the Topic (and probably never will) and don't want to intrude.
Thanks to isthisthingon BTW, for the heads up on which years to concentrate on first. I'm not sure where he/she gets the data, I did a few cross references and found that ANSS (which I use) had slightly less events for the 1985 period Oct-Dec.

edit: Done. Just to expand on that '85 "Great Swarm"
YS1985

The largest recorded earthquake swarm in Yellowstone occurred in the fall of 1985 in the northwest rim of the caldera. The three-month period of increased earthquake activity included over 3000 events of magnitude 0 to 4.9 (about 1800 events with magnitudes between 1 and 4.9).

isthisthingon has 700 events
I found 674 on ANSS
I have a file I got somewhere ages ago but can't recall where, its marked UTAH1982-2012, probably from the University of Utah
it has only 581 events for the same period

where's the rest?
Ha! probably what the 700+ pages on "What's going on at Yellowstone" are about .............

I was watching a video of the Holuhraun eruption filmed yesterday, on this web page. The bubbling cauldron of lava is beautiful.

At the 1:33 mark in the video, I took this screen grab below. I believe the view is looking South, toward the toe of the Vatnajökull icecap (Bárðarbunga would be much farther back in the distance and to the right).
Does the dark area the arrow is pointing to look like fresh lava, or just an outcropping of rock?

a reply to: Olivine
Great find!, I took some screenshots myself, amazing flyover

maybe that dark area is the gap in the ice cap shown in the aerial image below (volc. icon is the new Baugur cone, as seen in the vid)


having seen that video I don't think we are going to see Bardarbunga itself erupt, the caldera roof may just slowly subside and leave a deeper caldera. The lava is too free flowing at Baugur, a classic "cauldron"
I think what we are seeing is the birth of a new permanent volcanic cone
quite amazing to see it happen in front of our eyes.

Indeed. It certainly doesn't seem to be slowing down. Just think how large it will be if this eruption continues on for years.

Good call on the "gap". I bet you're right. Thanks for those maps Muzzy. They make it much easier to figure out what is going on, and where.

a reply to: Olivine

I did a page with the screenshots I took
volcanictremor.wordpress.com...
It wasn't easy ....... I set my Snagit to 10 second shots, then the damn vid stalled 3 times and I ended up with about 50 images all the same with that twirly gizmo in the middle of it
Sorted those out and put the rest on the page
not as dramatic as the actual video though.
I think I have got the directions right, although they might not be in the order he flew over, the vid is stitched together too.

a reply to: muzzy

QVSData has the built in facility to snap events down to 2 second intervals. Take a look at the view menu - web cam snapper. I used it during the Eyja outburst to collect the Vodafone web cam images. (In fact that was what it was created for)

a reply to: PuterMan

Oh yeah, forgot about that. Never used it.
I set everything up and it seemed to work to the point that the timer was ticking over,
but it came up "image save error"
I wonder if it is because the image I'm trying to save is a live video, not a jpg, png or gif?

Snagit works OK for the Bardarbunga web cams, I've set that up to just pick the image inside the frame and various timing setting, the only "snag" (pun), is that the page has to be open on your browser during the capturing. I tried the url setting but it won't work. Can't expect too much for a free program eh.

the problem with screenshooting the video Olivine posted the link to, was my broadband is the slowest in the developed world and it sometimes goes "dial-up" .ie the vid. decided it needed more time to load right in the middle of it.

a reply to: muzzy

Yes. Only works on static images.

a reply to: muzzy

I guess we all assume these things are done automatically, but maybe they are not and require analysis and creation by humans

Apologies, a shortage of electricity in Kverkfjöll (transmitter) prevents data flow from Bárðarbunga.

a reply to: PuterMan

cheers, at least I know now that it wasn't me that stuffed up

Bardarbunga-Holuhraun earthquakes back up in numbers, energy released up just a little
mag less than 1= 49 , mag1= 72 , mag2= 19 , mag3= 3 , mag4= 5 , mag5= 1
total= 149 , total energy released= 1,210.3805 TTNT
Looks mostly at Bardarbunga caldera, but the Dyngjujokull glacier/Holuhraun dike string is active again, but mag less than 1 mostly.
haven't done the maps and graphs yet, maybe after dinner



Will see what the Scientific Advisory Board of the Icelandic Civil Protection have to say, they have a meeting scheduled for today 13th, which for me is nearly over already. geez at this rate I'll have to make up my own reports!

Caldera now dropped 12 metres overall hraun.vedur.is...
