A volcano comes to life – satellite picture of Bardarbunga on Iceland
dlr.de...#/gallery/16367

Bardarbunga, (Bárðarbunga) in Iceland, one of the largest volcanoes in Europe and located beneath the biggest glacier in Europe, became active again in mid-August. For several years now, German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) researchers have been keeping a close eye on Bardarbunga and the system of volcanoes associated with it - an enormous network of subterranean magma channels, vents and craters. The German Earth observation satellite TerraSAR-X has now provided important data on the volcano's latest activity.

Early warning system for volcanic eruptions

The systems of volcanoes on Iceland have been at the focus of research by scientists at the DLR Remote Sensing Technology Institute (Institut für Methodik der Fernerkundung; IMF) for several years. The aim is to understand volcanic processes more exactly and develop new methods for the early detection of eruptions. Radar satellites provide comprehensive, highly precise data for this, regardless of the weather conditions and time of day. The process of detecting movements in Earth's surface - radar interferometry - has been especially optimised at DLR for the TerraSAR-X satellite. The remote sensing experts will now be generating more radar images of Bardarbunga and analysing changes in Earth's surface throughout the process.

Apparently, the sulfur smell has been noticed as far as Norway. The wind is bringing the sulfur towards Scandinavia. Here in Finland I haven't noticed the smell of sulfur yet, but I inform when I notice that.

Norwegians smell sulfur from Holuhraun
Smell of sulfur gas thought to be from the Holuhraun eruption, has been detected at the west coast of Norway, some 1300 kilometres away (807 miles) according to Norsk Radio, the public broadcaster in Norway. Sattellite photos have shown migration of gasses in that direction.

In a story published today on NRK´s website, meteorologist Vibeke Thynes says the most likely source of the smell is the eruption in Iceland; she says the sulfur gas is highly diluted and not at all dangerous to the public.

Yes, I told my husband this morning that while Iceland hasn't exploded yet, it's making Norway smell bad.

Of course, if this keeps up, it will be less and less funny as the gas concentrations get higher.

Eruption Concerns Spike at Iceland's Bardarbunga Volcano After Earthquake
www.wunderground.com...

After a brief lull, eruption concerns spiked again as a 5.5 magnitude earthquake shook an area just northeast of Iceland’s Bardarbunga volcano Wednesday morning.

Seismic activity first escalated around the volcano in mid-August. The Iceland Review reports the chance of an eruption is rising because the volcano's crater, also called a caldera, has been steadily sinking.

The crater has sunk as much as 65 feet since last week, Reuters reports.

Bardarbunga could sunk hundreds of meters
www.ruv.is...

Carton Bárðarbunga could possibly sunk hundreds of meters and a box sunk to the sea in the volcano causing great uncertainty about developments, since this does not happen in this country since basin was formed in the 19th century.

This is stated in the article by geophysicist Magnus Tumi Gudmundsson Ghana and Paul Einarsson on the website ies University. They say öskjusig can not be considered rare globally. Carton Bárðarbunga has depreciated by about 20 meters, but recent examples of hundreds of meters of volcanic öskjusig abroad.

M.

People will closely monitor mother
www.ruv.is...

Yet there's a reason people go ahead as planned to let your guard down because of pollution from the eruption site in the hollow lava.

Pollution caused by sulfur dioxide from a fire north of Vatnajökull shot up through the roof of the plant in the afternoon and was most 2550 micrograms per cubic meter at three o'clock, but it is by far the highest value ever recorded in Iceland.

In other words, if you live in Iceland do not get complacent because it is not going boom very fast. (So Far.)

Sinking Iceland volcano crater raises flood worries
news.yahoo.com...

REYKJAVIK (Reuters) - Iceland's Bardarbunga volcano registered one of its most powerful earth tremors yet on Wednesday while the sinking of its caldera raised concerns of an eruption and flooding, authorities said.

The caldera, the cauldron-like crater at the top of a volcano, had sunk by up to around 20 meters since last week as magma channeled through underground passages moves away from the volcano, Magnus Tumi Gudmundsson, geophysics professor at the University of Iceland, told public service broadcaster RUV.

Bardarbunga, not unsurprisingly is shaking:
I suspect we'll see a M6.+ in the next day or so.

Bárðarbunga Eruption Major Worry
icelandreview.com...

An earthquake of magnitude 5.5 shook the area to the northeast of Bárðarbunga this morning at 5:28 am.

The probability of an eruption in Bárðarbunga is now thought to be increased due to a steady lowering of the surface above the volcano’s crater. This greatly worries scientists and Civil Protection Department representatives, ruv.is reports.

a reply to: Moshpet

I really have my doubts about the magnitude of these quakes because the drumplots seem to tell another story.
Sure there was a quake, but not of such a magnitude, there was a M5.5 this morning which was clearly large quake if you look at the drumplots, but others seem to be more like an M2 at best.

This is where I got the data from:
en.vedur.is...=table

And that is the Icelandic Met Office's own server, and sensors.
As chincy as they are with their sensors (Eg no live feeds to GEE,) it is what we get.
I also suspect that their secondary net of webcams may be much better than MILA's.

*shrug*
This happened while I was out at dinner.

Have there already been three earthquakes on Sept II?

Massive Earthquake at Bardarbunga
www.ruv.is...

Earthquake of magnitude 5.2 was the eastern half Bárðarbunga shortly after midnight. Geologists and Civil Protection Deeply concerned by the physical settlement of Bárðarbunga probability of an eruption is thought to have increased after starting up in the box.

M.

the number of quakes for 10/09 was quite low, 128 of them, incl. that 5.5
Verdur is back on with data but it is only up to 2014/09/08 13:28:50
So what was the problem I wonder?
I'll go through and process the 7th which was the first day without reviewed data.
In the meantime it looks like the Vatnajökull - earthquakes during the last 48 hours (Preliminary results) will have to do.
Give me a few minutes and I'll map them for interactive viewing.

The night cameras are getting quite boring.
day cameras pretty much only showing which way the wind is blowing

What was that something?

a reply to: muzzy

Sorry for my late reply muzzy, i made that screenshot at 9 September, time 10:08.10 p.m.
There is a two hour difference between the Netherlands and Iceland so in Iceland the time was 08:08.10 p.m.
