  1. General Volcanic Activity Thread!

    Volcanoes Today, 9 Dec 2014: Turrialba volcano, Laguna del Maule, Aso Tuesday Dec 09, 2014 11:00 AM |Glow and ash emissions from Aso's Nakadake craterAso (Kyushu): Mild strombolian activity and ash emissions continue at Nakadake crater. Turrialba (Costa Rica): A new eruption occurred last evening at 21:30 local time. Not much detail about the eruptions is available, but it seems to have been a rather small event. Light ash fall was noted in areas up to 20 km distance. There are no reports of damage or injuries. A volcanologist from the National Seismic Network said in an interview that the new eruption possibly was triggered by the recent earthquakes in the region. Laguna del Maule (Central Chile): The volcanic field of Laguna del Maule is a potentially dangerous volcano. Scientists have found alarming levels of uplift, suggesting its magma chamber is filling up. What does this mean? In a recent study published at GSA, scientists try to give an answer.   http://www.volcanodiscovery.com/laguna-del-maule/unrest.html read the study its very interesting     "The rate of deformation at Laguna del Maule has been among the highest ever measured at a volcano that is not actively erupting", the authors write. It has been known since Roman times (and is still far from understood) that large, active calderas can undergo periods of significant up- and downlift of the ground. An example is the Campi Flegrei caldera which in parts rose more than 2 meters in just 3 years between 1982-85!

Today marks 100 days since the ongoing volcanic eruption in the Icelandic highlands began. A meeting yesterday between scientists from the Icelandic Met Office and the Institute of Earth Sciences at the University of Iceland, along with representatives from the Icelandic Civil Protection, the Environmental Agency of Iceland and the Directorate of Health concluded that there have been insignificant changes at the eruption site in recent weeks, but that seismic activity remains strong. Scientists currently believe the eruption will probably continue until the subsistence at Bárðarbunga ceases—meaning the eruption could continue for several more months. So far the eruption has caused the biggest lava flow for centuries and the dispersal of poisonous gas on the wind around Iceland. However, there has been no ash and no disruption to flights. The gas pollution today (Tuesday) is to the north and northeast of the volcano. Though most likely, there are also other possible scenarios: “The volcanic fissure may lengthen southwards under Dyngjujökull, resulting in a jokulhlaup (glacial flood) and an ash-producing eruption,†a statement from the scientists says. “It is also possible that eruptive fissures could develop in another location under the glacier. If such an eruption would be prolonged it could eventually produce a lava flow.†A volcanic eruption in the Bárðarbunga caldera is also still a possibility. “Such an eruption would melt large quantities of ice, leading to a major jokulhlaup, accompanied by ash fall. Other scenarios cannot be excluded.†http://icelandreview.com/news/2014/12/08/concerns-about-acid-spring-melt
  4.   havent looked at this for a few days   pressure looks to be on the up again (assuming the storms aint tainting these at present)

  6. General Volcanic Activity Thread!

    December 08 11:00 h (December 08 17:00 GMT) In the last 24 hours the monitoring system of Popocatepetl volcano recorded 70 low-intensity exhalations along with emissions of steam, gases and occasionally small quantities of ash.   http://www.cenapred.gob.mx/cgi-bin/popo/reportes/ultrepi2.cgi   pics and images in link above     http://www.cenapred.gob.mx/popo/2014/dic/p1208143.mp4

    Volcanoes Today, 8 Dec 2014: Cerro Negro de Mayasquer volcano, Erebus, Fogo, Pavlof, Sinabung Monday Dec 08, 2014 16:00 PM |The lava flow of Fogo passing near a destroyed building (image: INVOLCAN / @involcan / twitter)Fogo's lava flow reaching Bangaeira in the background - parts of destroyed Portela in the foregroundPyroclastic flow on Sinabung Saturday noon (source: Leopold Kennedy Adam â€@LeopoldAdam / twitter)Steam plume from Pavlof volcano on 5 Dec (AVO)Histogram of earthquakes at Chiles volcano (IGPEN)Seismic recording from Mt. Erebus on 5 Dec 2014Fogo (Cape Verde): The second village Bangaeira in the path of the rapidly advancing lava flow has been destroyed within only a few hours. With 2 villages destroyed, more than 1700 people displaced and without some of their most valuable economic possession, farmland, this now 15 days old eruption is the worst volcanic disaster of the century. The history of 150 years of settlement in the Cha caldera is now under lava. The flow continues to be well alimented, but it is still too early to predict how far it will eventually go: Following the natural gradient, it still needs to travel for another 4 km until it can reach the break-in-slope towards the steep outer eastern flank. From there, it could rapidly reach the coastal area where another 3 villages would be at risk: Corvo, Achada Grande, and Relva. No historic lava flow from inside the caldera (vents west of the Pico cone) seems to have achieved this, i.e. reached the sea,- so far. ...8 Dec: The new lava flow, more fluid than the earlier one, continues to advance rapidly. It has reached and started to engulf Bangaeira village, downslope of the already destroyed Portela village. If the eruption continues long enough, the lava flow, following the downwards slope, would eventually reach the eastern coast. Sinabung (Sumatra, Indonesia): The volcano remains active and dangerous although it has been generally quieter during the past weeks as compared to the surge in activity in Oct. However, sudden collapses of the still growing lava flow and/or explosions occur from time to time: a moderately sized, 2 km long pyroclastic flow traveled down the southern flank Saturday noon (local time). Pavlof (Alaska Peninsula, USA): Weak activity continues at the volcano. The volcano observatory showed photographs showing the volcano emitting a steam plume and reports seismic activity is still elevated. Increased temperatures at the summit, detectable on satellite data, are coming from the recent lava flow. Cerro Negro de Mayasquer (Colombia): Seismic activity continues to be important. In the last week, almost 20,000 earthquakes with a daily average of 2845 were detected. 5 of them were felt by the local population, the largest one was a 3.8 event on 2 Dec at 17:58 local time. Compared to October and November this year, when daily averages were 3740 and 4579, respectively, seismic activity has declined a lot, but remains high. The epicenters of most quakes are located a few kilometers south-west of the Chiles volcano. Erebus (Antarctica): The Mount Erebus Volcano Observatory (MEVO) reported yesterday that "it has been an active time for the last 24 hours. There were 6 significant eruptions which show up nicely on the MACZ (short period single vertical component) seismometer. ... There is no knowing if this will continue or was just a one off. It does show that gas is accumulating somewhere at depth and migrates to the lava lake as a big bubble where it bursts explosively sending volcanic bombs shooting above the lava lake and sometimes out onto the crater rim where people may be working."########################   http://www.volcanodiscovery.com/volcanoes/today.html
  8. hi mark   certainly some strange folk around   re friday   if we do see something it will likely only be brief   however it would be nice to see something even if only for looking at purposes   got plenty of winter left for the proper fun :)   this week is really a tricky week to call at present   i will update tomorrow night to see where we stand   off now   goodnight all
  9. friday is a tricky call   its a case of what comes first   the 528 dam air or the front to our far north west   maybe something wintry for us down here but not going there yet   gfs para shows this   but if the colder air digs in after it will likely be rain   will re check that again tomorrow night   saturday looks cold with a breezy north west flow   but dry at present   ukmo raw   for sunday bottom right   too far to call but looks a shade warmer at present   winds more westerly and from a warmer source there   all this is subject to change though

  14. Holuhraun Biggest Lava Flow in Centuries By Alëx Elliott December 08, 2014 03:25 Updated: December 08, 2014 07:53 If the Holuhraun volcanic eruption continues as it has done, then both the sinking of Bárðarbunga and the eruption itself can be expected to continue for at least several more months. The longer the current eruption continues, the less likely it becomes that Bárðarbunga will erupt, as had been feared. “Things could develop differently and scenarios involving an eruption under the glacier and in Bárðarbunga are still possibilities,†according to the scientific committee of the Civil Protection Agency, as reported by mbl.is. The scientists pored over data from the way the eruption and seismological events have developed since the beginning of the episode this summer. The earthquake swarm at Bárðarbunga is one of the biggest ever recorded in a mountain anywhere in the world—although the sinking of Bárðarbunga and the intensity of the Holuhraun eruption have both slowed of late. “Seismic activity and lava production are though still large-scale in comparison to eruptions in Iceland over the last hundred years,†the committee explained. Several days after the eruption started, the craters of Bárðarbunga began to sink by up to 80 centimeters a day. That rate has slowed gradually and now stands at about 25 cm per day. The new lava spewed out from Holuhraun represents the biggest lava flow in Iceland since the Skaftáreldar eruptions (1783-1784) and is likely the world’s third-biggest lava flow since that time.   http://icelandreview.com/news/2014/12/08/holuhraun-biggest-lava-flow-centuries   http://icelandreview.com/news/2014/12/08/high-so2-pollution-levels-southeast-iceland
