Iceland’s volcanic fissure eruption ongoing – caldera sinks about 20 meters

September 2014ICELAND Iceland’s Bardarbunga volcano continues to rumble, threatening to blow its top and throw tons of ash into the atmosphere like the Eyjafjallajökull volcano did in 2010. This time, however, scientists will be tracking the volcano minute by minute with an array of instruments that they hope will allow them to predict any impending eruption and give early warning of the dangers. Bardarbunga has been at “code red” twice since it started erupting on August 29th last blasting molten rock 100 meters into the air. The question is will it be an explosive release that could cloud the skies over Europe with ash, said Prof Simon Redfern, professor in Earth sciences at the University of Cambridge. “There is no sign of that happening yet.” He and four other volcanology experts joined today to talk about the risks posed by Bardarbunga at the British Science Association’s annual festival of science. These included Dr. David McGarvie of the Open University who was in touch by mobile phone from a tent pitched near where the eruption is taking place. The volcano currently bristles with monitoring equipment including 70 seismometers along with strain gauges to measure pressures underground. Some of these have been moved hastily to prevent them being covered by flowing lava.
Satellites overhead have been monitoring the rapid collapse at the centre of the volcano, its caldera. This is sinking down 90cm a day and since the eruption started it has dropped 20 meters, said Dr John Stevenson of the University of Edinburgh. “There are big movements going on here,” he said. This was an important eruption for earth science, and had much to teach us about volcanoes, said Dr. Susan Loughlin, head of volcanology with the British Geological Survey. “For the first time we will be totally monitoring and recording enormous amounts of data,” she said. The goal is to be able to predict an impending eruption and give as much early warning as possible. This has proved a difficult challenge however despite the instrumentation. These note tremors and minor earthquakes, but volcanoes like this only erupt once in 300 years so there is little comparative data on patterns of behavior, Dr. McGarvie said. Even so they know that recent past eruptions were preceded by dozens of small tremors. “We are much better prepared for any eruption,” he said. Eruptions cause local impacts in Iceland with dangers posed by noxious gas emissions and the risk of severe flooding if the eruption starts under a dome of ice. Europe however fears ash cloud discharges that can follow explosive eruptions under ice. Early warning would be a major help for aircraft and also information about the movement of ash clouds.
Preliminary data from the European-Mediterranean Seismological Centre indicated another significant earthquake in the vicinity of the volcano Wednesday evening, with a magnitude of 5.1. Seismic activity first escalated around the volcano in mid-August. The Iceland Review reports the  because the volcano’s crater, also called a caldera, has been steadily sinking as much as 65 feet since last week, Reuters reports. The Eyjafjallajökull ash grounded 90,000 flights over Europe, Dr Stevenson said. Here too however we are better prepared this time around. “The computer models are really good at predicting where the ash is going to be,” he said. And a laser-based device that can measure ash density in the air has been installed near Bardarbunga. It will be used to indicate whether any ash released exceeds the four micrograms of ash per cubic metre limit for commercial aircraft flying through the cloud. –Irish Times

    We are within 30 days of the second of four blood moons that are occurring on Major Feast Days of Israel. We live in significant times. Not only are our eyes on this event, but also activity in Yellowstone. Everybody forgets that more than one super volcano can erupt (not calling this one a super volcano) and others.

    We do not know whats going on beneath us…….. I think……..

      Yes Dennis. And as well double eclipses, in aries (hot-headed pioneer) and scorpio (dark deep intense water ’emotional’ creature).

      As well… year of the horse is all about power (horse-power) and shamanic skunk year (respect & reputation).

      Connect the dots folks and pratice living impeccably. The book The Four Agreements is great help.

    People are waiting for THE eruption while it’s already ongoing. Around the world we have floods, strange weather and this week-end CME will ignite more quakes and weather anomalies. We are in the process, don’t wait for the “doomish” eruption…


  3. Dennis E. says:

    There is a story that it is being reported that lava is leaking out 25 miles away.
    Also, there is an estimated 1 trillion gallons of water in ice in the crater.
    Some say it will be like a shaken soft can drink when opened.

    According to prophesies we’re living at the present, half way through the book of Revelations, Apocalypses! War world 3 is already on…

      The beginnings of the Time of Sorrows. Our King will soon return to judge this world.

      like most of american protestantdom, i was raised to assume the pretrib view was the correct understanding of End Time prophecy…

      but over the past couple years, i have more and more begun to consider that the midtrib understanding may be closer to the truth… i have to agree, our world may be experiencing the beginning visitations by the horsemen

      we who have become Watchers should all be living in deep intercessory prayer for the whole world- not Watchers only, but Witnesses as well

    any significant eruption will affect global warming: either due to heat from the lava, or cooling from the resulting ash-cloud. After one of those, GW will never again be implied to be man-made.
