Sulfur pollution from the eruption site in the hollow lava rose in the East in the afternoon, both on the plant and recommend the Egilsstöðum. Highest at the concentration of sulfur dioxide Reyarfirði almost 650 micrograms at about 13:20 but quickly dropped back.
Weather service warns of high concentrations of sulfur gases from the eruption of lava in the hole. It can be expected that the area of the northern east coast north Weaponfirth will be most affected. Gasgrímur and gas meters rokseljast because of the eruption. Lage has run twice at the biggest seller.
Do not reduce the eruption of lava pocket. This was stated at a meeting of scientists Council this morning. Based on observations at the level of volcanic activity is similar to the last few days.
Lava flows eastward small proportion spreads out to the north side of the tongue flows on the Jokulsa the mountains and the river flæmist east lava. Not in explosions where lava flows into the river, but gufubólstrar ascend to heaven.
The uncertainty about the progress of the eruption of Bárðarbunga. 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. Helgi Björnsson glaciologist says being important to know the terrain under Bárðarbunga.
Then is also important to examine the exact thickness of the ice. He says to go to erupt within the box is the serous matter, not least because Feykir relative Gross head, but mugs carton in the 1800 meters so the water there would be the melting would break loose down a large steep, five times more steep than when the eruption of Dyngjujökli and eruption. If gysi the edges is essential where the eruption occurs. If it's outside of the basin can erupt lead anywhere, Skjálfandafljót Dyngjujökullinn Jökulsá and down the mountains, south to Grim water and Köldukvís.
For some reason, a few people seems to think that 'the closings around the blowout Lava Do not Apply to Them. People without proper authorizations,-which are Issued to Scientists and I sometimes Journalist, have been arrested around the blowout lava eruption.
Willow Reynisson, Department Manager at the Department of Civil Protection stresses the importance of respecting the closings. They are for your own good.
"People in the town of Reydarfjörður experienced a great deal of discomfort yesterday Because of gases from the eruption. The distance from the site of the eruption to the town are some 80 kilometers," Willow said in an interview with mbl.is
In this article, updated information on the Bárðarbunga seismic events and volcanic activity is given with daily fact sheets and/or status reports. New material is added to the top of the article. The original information is at the end of the article. Therefore, bottom to top, this article gives an overview of events. Below is a calender with a short-cut to each day within this long text:
While international concern about an eruption at Bárðarbunga is focussed on flight disruption, a jökulhlaup (meltwater flood) is the most destructive potential outcome of a subglacial eruption. It would travel north from the glacier along the Jökulsá á Fjöllum river, and for this reason roads have been closed in the area. Edwin Baynes is a PhD student at Edinburgh University who studies past jökulhlaups in this area. In this guest post, he puts such a potential flood in context.
The Richter magnitude scale (also Richter scale) assigns a magnitude number to quantify the energy released by an earthquake. The Richter scale is a base-10 logarithmic scale, which defines magnitude as the logarithm of the ratio of the amplitude of the seismic waves to an arbitrary, minor amplitude.
As measured with a seismometer, an earthquake that registers 5.0 on the Richter scale has a shaking amplitude 10 times that of an earthquake that registered 4.0, and thus corresponds to a release of energy 31.6 times that released by the lesser earthquake.
The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs (adjustments are included to compensate for the variation in the distance between the various seismographs and the epicenter of the earthquake). The original formula is:
M_\mathrm[L] = \log_ A - \log_ A_\mathrm(\delta) = \log_ [A / A_\mathrm(\delta)],\
where A is the maximum excursion of the Wood-Anderson seismograph, the empirical function A0 depends only on the epicentral distance of the station, \delta. In practice, readings from all observing stations are averaged after adjustment with station-specific corrections to obtain the M_\text[L] value.
Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude; in terms of energy, each whole number increase corresponds to an increase of about 31.6 times the amount of energy released, and each increase of 0.2 corresponds to a doubling of the energy released.
The caldera in Bard Bunga volcano could subside by hundred of meters, say two of Iceland's top geophysicists. The caldera has sunk in recent days by at least 20 meters, increasing the likelihood of an eruption there.
In a short article published yesterday, geophysicists Magnus Tumi Gudmundsson and Pall Einarsson at the University of Iceland's Institute of Earth Sciences state that 'the subsidence in Bard Bunga eventing makes it harder to PREDICT future development of events in north-western Vatnajokull glacier. A magma intrusion has migrated some 40 kilometers from beneath Bard Bunga, to the north, Leading to a lava eruption north of the glacier's margin, in the lava field of lava pocket.
Dramatic images of the volcano Bardarbunga violently spewing lava and molton ash have emerged - suggesting that Iceland was quite right to ban all flights over the area.
Craters spit out lava as molten rock flows into a river in the stunning images taken over the Holuhraun lava fields in the Icelandic highlands.
The country's Met Office issued a 'red alert' at the end of August after the Bardarbunga volcano, which lies underneath the Vatnajökull glacier, experienced a 'small' eruption.

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.
