  3. Gas-spewing Icelandic volcano stuns scientists Icelandic sunrises and sunsets have been tinged blood red, of late. Above the maritime bustle of Reykjavik’s harbour and the city’s towering concrete Hallgrímskirkja church, volcanic pollution gives the skies an eerie glow. For eight weeks, lava has been spurting out of a fissure in the ground radiating from the Bárðarbunga volcano, about 250 kilometres from Reykjavik. Sulphur dioxide has been spurting too — 35,000 tonnes of it a day, more than twice the amount spewing from all of Europe’s smokestacks. The gas has spread across the Icelandic countryside, causing people to wheeze and trapping some indoors. The record-setting amount of pollution has surprised even volcanologists in the middle of a major project funded by the European Union to understand the island’s fiery activity. They had been preparing for a repeat of the 2010 Eyjafjallajökull eruption, which led to a billowing ash plume that grounded planes across Europe. “Everybody was expecting a big ash cloud, and now we have something totally different,†says Anja Schmidt, an atmospheric modeller at the University of Leeds, UK, who studies how volcanic gases spread. The timing of the eruption was just about perfect for the project, called FUTUREVOLC. The initiative aims to use Iceland as a natural laboratory to understand how magma makes its way from deep in Earth’s crust to the surface — to do so, its organizers have focused on four of Iceland’s most active volcanoes, one of which is Bárðarbunga. The researchers used extra seismometers and global-positioning-system (GPS) stations to bolster the monitoring network maintained by the Icelandic Meteorological Office and the University of Iceland, both in Reykjavik. And they used these to measure the events leading up to and after the eruption with unprecedented detail. Earthquakes began shaking Bárðarbunga on 16 August. For two weeks, researchers watched as seismic activity marched north and east, towards the edge of the ice cap that covers the volcano. GPS stations measured the ground flexing upward as huge amounts of magma shifted underground. “The seismic shows us the detail, and the GPS shows us the volume,†says Kristín Vogfjörð, a seismologist at the Icelandic Meteorological Office and co-leader of FUTUREVOLC. Since then, the eruption has spewed at least half a cubic kilometre of lava, making it the largest lava-producing eruption in Iceland since 1947. But the quantity of gas is what has startled scientists most. Chunks of rock collected from the eruption show how gas-rich the lava is; the rocks are porous, filled with air pockets where the gas has leaked out. With the right winds, the sulphur that Holuhraun produces can reach as far as the European continent, where Austria has recorded more sulphur in its air than any time since the industrial clean-up of the 1980s. Icelandic officials are trying to work out how much of a hazard the sulphur is and whether they can predict its movement more accurately. The meteorological office has begun issuing forecasts of where the gas is likely to travel each day. Sulphur spikes as high as 21,000 micrograms per cubic metre were measured last weekend in the town of Höfn; the World Health Organization recommends no more than 500 micrograms per cubic metre for a 10-minute exposure. In Iceland, the last similar event was a fissure eruption known as the Krafla fires that began in 1975 and lasted on and off until 1984, says Freysteinn Sigmundsson, a volcanologist at the University of Iceland and co-leader of FUTUREVOLC. If the current eruption is tapping magma deep in the crust, as the lava’s volume and chemistry suggest, then it, too, may continue for months or even years. http://www.nature.com/news/gas-spewing-icelandic-volcano-stuns-scientists-1.16234?WT.mc_id=TWT_NatureNews link supplied have reduced this down for posting here click on link for full story

  10. Kilauea volcano update: Lava only approx. 500 m from Pahoa village road Monday Oct 27, 2014 18:28 PM | BY: T Updated lava flow map at Pahoa, Hawai'i (image: HVO) Lava flows continue to approach the center of Pahoa and might reach it within few days. from HVO's latest update: The relatively narrow finger of lava that crossed ApaÊ»a Street yesterday morning continued to travel downslope, splitting into two lobes as it advanced. The faster, northern lobe crossed completely through the PÄhoa cemetery by mid-morning, while the slower southern lobe was advancing through open pasture south of the cemetery. Another lobe farther upslope, just above ApaÊ»a Street, advanced about 50 meters (55 yards) since yesterday. Over the course of the day, the advance rate of the narrow finger that crossed the cemetery varied from about 10 and 15 meters per hour (11 to 16 yards per hour), which is equivalent to 240–360 meters per day (260–390 yards per day). As of 5 PM, the faster-moving finger was about 390 meters (425 yards) downslope of ApaÊ»a Street and 660 meters (720 yards) upslope from PÄhoa Village Road. It had an average width of about 40 m (45 yd). The slightly slower-moving southern lobe in the pasture south of the cemetery reached slightly steeper terrain at mid-afternoon today, and was traveling at about 9 meters per hour (10 yards per hour) at 5 PM. It will likely rejoin with the finger that came through the cemetery near the northeast end of the pasture. The pasture is located between two of the steepest decent paths plotted on HVO’s lava flow maps, and the flow is trending toward the southerly of these two paths. This path joins the northerly steepest-descent path about mid-way between the cemetery and PÄhoa Village Road, so the inferred flow path leading to PÄhoa Village Road is unchanged.

  12. Monday 27.10.2014 08:23:29 63.637 -23.468 9.8 km 3.7 99.0 10.0 km WSW of Geirfugladrangur http://en.vedur.is/earthquakes-and-volcanism/earthquakes/reykjanesridge/#view=table just something that i noticed earlier maybe nothing but worth keeping an eye on http://www.volcanodiscovery.com/reykjanes.html
  13. http://www.livefromiceland.is/webcams/bardarbunga-2/ still see this on cam 2 looks lively still
  14. https://twitter.com/edwinbul/status/525731035934625792/photo/1 after seeing that pic in link and then the report from imo as posted by allseasons earlier i assume the pic above is what they are referring too 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. Observation from air on Friday show that the depres sion in the caldera is 40 meters. ï‚· Geothermal heat is increasing in Bardarbunga. A cauldron in the southeast corner of Bardarbunga has deepened about 25 meters over a one month period. The depression is considered to be linked to the depression of the Barda rbunga caldera http://en.vedur.is/media/jar/Factsheet_Bardarbunga_20141027.pdf hi norfolk i thought 25% was pretty high too
  15. http://icelandreview.com/news/2014/10/27/over-200-earthquakes-bardarbunga-over-weekend quick link to read and Pollution Warning in Höfn: Keep Kids Inside By Eygló Svala Arnarsdóttir October 27, 2014 09:15 The pollution in the East Fjords in early September. Photo: Zoë Robert. The Civil Protection Department advises people living in and around Höfn, Southeast Iceland, to drive their children to school today and to keep the children inside during breaks because of extreme sulfur dioxide (SO2) pollution from the eruption in Holuhraun. SO2 levels measured 1,200 mµ/m3 in Höfn this morning but between 4,200 and 6,600 mµ/m3 in the nearby rural areas Mýrar and Suðursveit. SO2 levels exceeded 21,000 mµ/m3 in the region yesterday. Inhabitants were advised to keep their windows closed during the night. Continued eruption pollution is forecast in Southeast Iceland today, ruv.is reports. “The model we use to monitor the gas distribution indicates that there will be pollution in that area on an off during the next 36 hours and [it will] move to the east late in the night,†stated director of the Civil Protection Department Víðir Reynisson. The website of the Environment Agency of Iceland reads that at SO2 levels higher than 2,000 mµ/m3 everyone may experience respiratory symptoms, especially individuals with underlying diseases. Above 9,000 mµ/m3 the symptoms grow more severe and above 14,000 mµ/m3 the situation is considered to be hazardous. Further information on the volcanic gases in English, including a link to a map showing pollution meters in different locations in Iceland are available on the agency’s website. http://icelandreview.com/news/2014/10/27/pollution-warning-hofn-keep-kids-inside not too good that anyway, hi all cannot stop as off out but be back later
  16. M 4.4 - ICELAND - 2014-10-27 01:05:32 UTC http://www.emsc-csem.org/Earthquake/earthquake.php?id=405897 be around 4,7-4,8
  17. http://en.vedur.is/earthquakes-and-volcanism/earthquakes/#view=table looks like updates may be done in the morning again unless we get a biggie on csem of course so i am just going to watch the cams for now :) computer still slow at present allseasons (think broadband a bit slow tonight) be back a little later
  18. Volcanoes Today, 26 Oct 2014: Kilauea volcano Sunday Oct 26, 2014 10:00 AM | The June 27th lava flow crossed ApaÊ»a Street / Cemetery Road at 3:50 AM, HST, Saturday morning, October 25, 2014. In this photo, which was taken at about 9 AM Saturday, the flow is moving from right to left, with burning asphalt visible along it's NW margin. A utility pole, far right, was surrounded by lava but remained standing at the time of the photo. The hope is that the protective insulation and cinder/cement barrier around the pole will prevent it from burning through. (image: HVO) The 2 active lava fronts advancing towards Apa'a Street just before the contact earlier today (HVO) Kilauea (Hawai'i): Lava has crossed the ApaÊ»a Street / Cemetery Road near the driveway to the PÄhoa cemetery and is now spreading mainly over open grassland. Between 40 and 50 households could be evacuated within the next few days, as soon as Tuesday, if the lava continues to advance at current rates (approx. 250 m per day) and follows the most likely paths. The lava flow front, approx. 70 m wide, is headed northeast and only 1 km straight line distance from Pahoa Village Road,†he said. The best guess of HVO is that the lava might cross Pahoa Village Road a little bit west of the Pahoa Post Office. The Hawaii Electric Light Company is trying to protect their wooden utility poles by encasing them with concrete, and thus, preventing the lava to burn it, but rather flow around them. So far, one pole engulfed in the lava flows have survived, but as the flows inflate, their fate might be different
  19. hi allseasons certainly a nice display tonight having a few gremlins in my computer be back soon
