Orange Alert Issued for Iceland’s Bárðarbunga Volcano

by Crane-Ststion

Following a swarm of 2600 earthquakes on Saturday in and around Iceland’s Bárðarbunga Volcano, the Icelandic Meteorological Office (IMO) reports that the Bárðarbunga civil aviation color code has been raised to “Orange.” IMO defines this alert: “ORANGE: Volcano shows heightened or escalating unrest with increased potential of eruption.” IMO reports:

The intense seismic activity that started on 16 of August at Bárðarbunga persists. Very strong indications of ongoing magma movement, in connection with dyke intrusion, is corroborated by GPS measurements. There are currently two swarms: one to the E of Bárðarbunga caldera and one at the edge of Dyngjujökull just E of Kistufell. At 2.37 am on the 18th a strong earthquake (M4) was located in the Kistufell swarm.

This is the strongest earthquake measured in the region since 1996. As evidence of magma movement shallower than 10 km implies increased potential of a volcanic eruption, the Bárðarbunga aviation color code has been changed to orange.

Yesterday, the National Commissioner of the Icelandic Police (NCIP) reported that evacuations are beginning, in preparation for the volcano’s eruption.

The Bárðarbunga volcano system is about 700 meters beneath the ice. Bárðarbunga is a stratovolcano. Also known as a composite volcano, the stratovolcano:

is a conical volcano built up by many layers (strata) of hardened lava, tephra, pumice, and volcanic ash. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile and periodic explosive eruptions and quiet eruptions, although some have collapsed craters called calderas.

A stratovolcano is not a supervolcano. By way of historic comparison, two notable stratovolcanoes include Krakatoa (1883) and Vesuvius (79 AD), whereas a notable historic supervolcano includes Yellowstone. Mount Saint Helens is a stratovolcano.

The alert levels are a type of early warning system, and they are issued in cooperation with the International Civil Aviation Organisation (ICAO). Iceland’s Eyjafjallajokull Volcano eruption in 2010, for example, interrupted large portions of European airspace until atmosperic ash returned to safe levels for air travel.

International Business Times reports:

Intense seismic activity observed at Iceland’s Bardarbunga on Saturday has prompted the country’s Met Office to issue a warning for airlines about a potential eruption at the volcano, which is located beneath Vatnajokull, Europe’s biggest glacier. Officials said they have noticed very strong signs of magma movement through underground fractures.

On Monday, the Met Office changed the Bardarbunga aviation color to orange, which is the fourth level on a five-grade scale and indicates “heightened or escalating unrest with increased potential of eruption.”

  1. Two sides to a story says:

    Nature will likely put on a show that overshadows all other earthly concerns. Stay tuned for more climatic chaos.

    At least in Iceland they know how to do government. It’s just those mountains that cause destruction, not the govt.
    BTW, Iceland is the first country in the world that had a real feminist party in its parliament. Way ahead of the rest of everybody else’s time.

        That article appears to have been written in 2008. Has there been any change since then.

          JJ, Most nations that have a press that is some what free to report on the internal problems of that nation reveal that the problem’s of the nation never really go away, only the priorities of the news media shifts. A free press is not only the greatest ally of the people, it is also it’s worst enemy, as they have the ability to control opinion, and create internal unrest, and just as quickly they can cause internal or external problem to improver or deteriorate. We as a people often forget that freedom comes at a high price, and few are willing to pay that price, but prefer to coast along on the coat tails of those who sacrifice to make progress… Too often we as a people are unwilling to make an effort to realize that there is in most cases at least two sides to any story, yet we fail to consider that the version we are so quickly to accept is often not the complete truth… So to answer your question, the answer is yes and no, depending on who is doing the reporting.

      Malisha, Unfortunately, there are few locations on this planet that do not have racial discrimination problems. With the 2014 elections rapidly approaching, IMO the racial problems in this nation will quickly escalate into a political prize in which we the citizens of this nation are simply pawns used for the benefit for the upper class. It does no good to attempt to warn people to open their eyes, it only causes a backlash against the folks that bear the warning… Racial division in this nation is a great weapon that is being exploited quite well at the present time…

      They also let some banks fail and they put some banksters in jail. How refreshing.

      So glad I’m not a reporter who has to try to pronounce the Icelandic names. But then, how many can pronounce Tioughnioga or some of the many communities on Long Island?

      • crustyolemothman says:

        bettykath, Yes they did allow some banks to fail, and while it would have been popular in some quarters of our political society to have allowed the same to happen here, there was a big question as to the end results if it took place in this nation… It is quite possible that it would have resulted in complete economic collapse, so the risk was too great to not prop up the banks. Now IMO the bankers that led us into the problem should not only have been removed from their positions, they should have faced the criminal justice system as well…
