I do other stuff you know!
but it seems just to roll on at Bardarbunga
New Record for M3's yesterday (24th Oct) at the Caldera
mag3= 28 , mag4= 8 , mag5= 1
previous record was 24th August with 17 x M3's (older graphs here)

this latest image didn't make the animation. I will post them to the CalderaTopoImage page anyway, at the bottom

Bardarbunga Caldera

This animation is interesting
see how all the seismic activity has shifted east between Sept and October, or at least contracted to the shape of the Caldera
I didn't put the Caldera Rim Outline in, that seems to improve the quality
the Oct marbles pretty much shows where its at anyway

The animations keep rolling off the laptop

i started out doing Herdubreid-Herdubreidartogl but got sidetracked to Upptyppingar

I like the name Upptyppingar, its like something out of a Lewis Carrol Alice in Wonderland story, actually a lot of Icelandic placenames do.
Where is the Cheshire Cat? in Upptyppingar? ha ha

anyway, a blast from the past

Upptyppingar Swarm 2007

I see an opportunity for more animations featuring Iceland, especially from Eyjafjallajokull-Katla in 2011 and of course all these can be broken down further from monthly images into weeks or days, depending on what kind of detail you want.
edit on 1000000029829814 by muzzy because: (no reason given)

spent a lot of today trying to figure out the quality of the images. It seems when I start off with GIFs they can vary in colour between images, particularly the white icons lose their brightness, and the landscape changes dark to light sometimes, makes the animation seem splotchy, if I start with PNG images and convert them to GIF before creating the animation, they can look grainy on the animation.
Bit of a compromise necessary, I prefer consistent colour, so my animations may appear a bit grainy.

Bardarbunga-Holuhraun

Does anyone ever click on the little Volcano icon on the interactive maps?
Up till IMO stopped the daily reports I had a summary of those in there.
Now, a new feature, "Mila Web Cam Image of the Day"

Because there isn't much to see now with the snow covering the cameras, there isn't much to work with to put up separate Web Cam Images pages like I did earlier.
I have a few days stored that need editing, but really there has been nothing to see of any value since 19th Oct
So instead I have put the best pic inside the popup tag of the eruption icon

Starting today.

Upptyppingar Swarm 2007


On that page there is a summary of the 2007 swarm series and it mentions
"At the end of 2007, over 5,300 earthquakes had been detected and the region remained seismically active into 2008"
I got that from a pdf I found called
EARTHQUAKE SWARMS AT UPPTYPPINGAR, NORTH-EAST ICELAND: A SIGN OF MAGMA INTRUSION?
but wasn't sure how long this went on until just now, doing 2008.
holy smokes! March 2008

rightclick"viewimage"forfullsize

this is why researching earthquakes is so addictive, I have always been the type of person who wants to see whats just over the hill. I guess I won't be done until I get all the IMO data processed, this is a massive project, over half a million quakes in the database.

This Bardarbunga-Holuhraun series appears to be seismically unique for Iceland, so many M5's!!

That tapered away after March 2008, to be replaced with the aftershocks of the Mt.Ingolfsfjall M5.67 on 29/05/2008 at 15:45:58, which produced 10,647 aftershocks in the next 7 months to the end of 2008, in the area between Hveragerdi and Selfoss, also known as Olfus
That had 42 foreshocks on the 29th at 4.3-6.4km depth so there was some warning (if anyone has been watching) and in some papers have described it as a doublet with a composite magnitude of 6.1Mw
But that's another story, worth its own page

Daily status report 31. October 2014 - compiled by IMO (Icelandic Met Office) and IES (Institute of Earth Sciences)
The volcanic eruption in Holuhraun continues with similar intensity. The lava field is now 65,7 square kilometres.
The GPS station in the centre of Bardarbunga show that the subsidence of the caldera continues with similar rate as it has done over the last few weeks. The total depression in the caldera is now about 42 meters.

Costa Rica emergency officials on alert following explosions, ash spewing at Turrialba Volcano

Loud rumblings and ash covering roofs, gardens, roads and cars are the first results of increased activity at Turrialba Volcano, located northeast of the province Cartago, that started late Wednesday evening. According to the National Seismological Network (RSN), the eruption is the volcano’s largest in 150 years.

Experts from the University of Costa Rica (UCR) and National University (UNA) reported increased seismic activity on Wednesday afternoon, and at 11:10 p.m. they recorded a phreatic explosion at the volcano. The fumarole from the explosion reached several hundred meters, Carlos Ramírez, a vulcanologist at the crater, told The Tico Times. Ramírez said that the eruption involved ash, rocks and possibly magma.

Iceland October 2014
Fat Lady can't sing on October yet, bit of a anomally Oct 16-20 on the graph, needs further investigation.
Keeping in mind this data is reviewed and supposedly has 99% quality.


Figures for Preliminary data from IMO were;
17th - 70
18th - 48
19th - 58

Reviewed data from IMO shows for all of Iceland
17th - 17
18th - 26
19th - 17

unless I did something wrong in the processing
I'll have a look into it

In the meantime here are some new Caldera maps to look at for October
I can't give you the figures for the Caldera (or even the whole Vatnajokull area) yet as I need to break those out of the overall Iceland data.






combined


and finally, all magnitudes since Aug 1st


rightclick"viewimage"forfullsizeversions

maybe I should start a new topic just on Bardarbunga Caldera?, there are so many things you can do with the IMO data
I may be flooding Volcano Watch 2014 with too much Bardarbunga stuff???


edit on 11u30430414 by muzzy because: rightclick"viewimage"forfullsizeversions


on review reviewed data vesrus the preliminary data;
Border Search Co-ordinates for the area IMO call Vatnajokull
65.302642, -18.304362
64.115824, -15.565144

October 2014
Reviewed data
magless1= 767 , mag1= 1198 , mag2= 318 , mag3= 217 , mag4= 137 , mag5= 22
total= 2659 , total energy released= 38,745.5394 TTNT

Preliminary data
magless1= 699 , mag1= 1214 , mag2= 301 , mag3= 203 , mag4= 127 , mag5= 25
total= 2,569 , total energy released= 36,311.021 TTNT
In conclusion;
more less than M1's, less M1's, more M2's, less M3's, more M4's, less M5's
more energy released

I checked it out again and the results are correct.
This is where one must treat the Conclusions of the Scientific Advisory Board of the Icelandic Civil Protection with caution, for example they say in the 31st October report;

200 earthquakes have been detected in the caldera over the last 48 hours. Just over ten earthquakes were bigger then magnitude M4,0. The largest one was M5,3 tonight at 01:30.
Around 20 smaller earthquakes are detected in the dyke and at the eruption site in Holuhraun, all around magnitude M1,0 and smaller.

So they are talking in terms of 48 hour period, in this case covering the 30th and 31st Oct (because the 31st is the day of the 5.3 @ 1:30)
The IMO data only shows 96 earthquakes total for the 48 hours.
So they are quoting automatic preliminary data, including below 90% quality
that doesn't stack up on review.

This Bardarbunga activity has been ongoing longer than anyone expected, and there is no signs of stopping, the activity has remained similar for quite a long time. This activity is quite rare, sign of something changing. If this still continues, there is increasing change of big changes in Vatnajökull glacier. I'm surprised how long the caldera has stayed intact with that deflation, common sense says at some point it should break.

a reply to: Thebel

The Scientific Advisory Board of the Icelandic Civil Protection said the other day total deflation of the caldera was 42metres, yet the graph IMO puts out only shows 20metres.
Even so depends where the main magma chamber roof is at, Bardarbunga is 2000 metres high, 42 metres is nothing.
They say nothing about Baugar (the new cone down on Holuhraun lava field created by the fissure eruption) it must be at least 42 metres high now.

a reply to: muzzy

They placed the GPS in the caldera after it had already deflated by 20 meters or so (the initial deflation prompted them to place a gps) they include it in the total deflation when mentioning it in updates.

I can't remember how they could tell it had dropped though or how accurate there estimates were.

a reply to: LadyTrick

Yeah that makes sense, I see the first date on the GPS graph is 12/09/2014, almost a month from when the quakes started. Thanks for clearing that up.
I would have thought it would be better to include that 20m in the graph i.e. instead of starting at 0m, start the blue line at 20m.
Perhaps the line wouldn't look so steep then, as time goes on it will get steeper, as the Y axis compresses.
