B\u00e1r\u00f0arbunga Volcano, Under The Ice Cap of Vatnaj\u00f6kull Glacier, Showing \u00a0Signs of Possible Eruption<\/b><\/p>\n

B\u00e1r\u00f0arbunga volcano, an active subglacial stratovolcano located in Iceland under the huge Vatnaj\u00f6kull Glacier, has recently had hundreds of earthquakes that scientists believe are from the movement of underground magma.<\/p>\n

B\u00e1r\u00f0arbunga volcano is a subglacial ( under a glacier ) stratovolcano. \u00a0
A stratovolcano, also known as a composite volcano, 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.<\/i> \u00a0\u24d0<\/p>\n

B\u00e1r\u00f0arbunga has been rumbling at least since last Saturday.
The intense earthquake swarm continues with no significant changes. There are no signs of magma migrating towards or reaching the surface are present, although the risk of a subglacial eruption in the near future remains high. This could lead to significant glacial floods and ash emissions, which in turn could cause again disruptions of flight operations in the region, depending on the wind trajectories and the amount of ash released.<\/i> \u00a0\u24d1<\/p>\n

Earthquake activity has recently increased underneath B\u00e1r\u00f0arbunga.
A magnitude 4.0 earthquake hit in B\u00e1r\u00f0arbunga volcano at around 11:00 am this morning. The earthquake was at a depth of 3 km, which is much shallower than most of the other earthquakes in the area in recent days. Two other earthquakes, of magnitude 3.8, also occurred in the volcano before midday, <\/i>ruv.is<\/a><\/i> reports.<\/i> \u00a0 \u24d2<\/p>\n

Scientists are worried that the possible eruption of this volcano may cause massive flooding in Iceland.<\/p>\n

In Iceland people wait for the possible eruption of B\u00e1r\u00f0arbunga volcano with a strange combination of excitement and anxiety. The earthquakes continued through Wednesday night and into Thursday morning, but there is still no sign of magma making its way to the surface. Scientists are cautious because nobody wants to be the one who falsely predicted an eruption, but even so they seem to be leaning towards the opinion that probably the old volcano is waking up.<\/i> \u00a0\u24d3<\/p>\n

The eruption would be under a glacier between 150 and 600 meters thick. That means the ice would melt and J\u00f6kuls\u00e1 \u00e1 Fj\u00f6llum, a glacial river, would flood. The river might increase 10 to 40-fold. After the start of an eruption the water would take about an hour to reach the border of the glacier. It would be at Her\u00f0ubrei\u00f0arlindir in four and a half hours, at the bridge by Gr\u00edmssta\u00f0ir in seven hours and down to \u00c1sbyrgi, a natural pearl [port], in about nine hours.<\/i> \u00a0\u24d3<\/p>\n

This volcano could also cause disruptions to air travel.<\/p>\n

A volcanic eruption in B\u00e1r\u00f0arbunga could have a great an impact on air travel as the 2010 Eyjafjallaj\u00f6kull eruption did, according to Fri\u00f0\u00fe\u00f3r Eydal, a spokesperson for ISAVIA, the company which operates airports in Iceland.<\/i> \u00a0\u24d4\u00a0<\/p>\n

Overall assessment<\/b>\u00a0
There have been no observations of migration towards the surface or any other signs of imminent or ongoing volcanic activity. We cannot exclude that the current activity will result in an explosive subglacial eruption, leading to an outburst flood (j\u00f6kulhlaup) and ash emission."<\/i>

Throughout history there have been large eruptions every 250\u2013600 years.<\/i> \u00a0The last large eruption was in 1480.
Eruptions appear to follow a cycle: there were several eruptions in the glacier between 1701\u201340 and since 1780. There hasn’t been an eruption in the glacier or the system since 1862-4.<\/i>
