"It Will Be Unlike Anything Ever Seen in Recorded History"


This is the first notice of serious concern regarding this volcano.  On top of all that we are talking about this:

'Approx 8600 years ago, Bardarbunga produced the largest known lava flow during the past 10,000 years on earth (more than 21 cubic kilometers of volume). The lava was erupted from the Veidivötn fissure system and traveled more than 100 km to the south coast.'

The quoted diameter is wrong.  It is 6000 feet and not 6 miles. However it is part of the system that has dumped the above quoted volume so there is no comfort there.  another source quote 80 sq kilometers though.

What i am trying to say is that this able to shut Europe down agriculturally for twenty years as did occur in 1159BC.  Sidestepping that level of disruption will be a huge challenge to all governments.

►"The lava under the Bardabunga crater is draining out from the crater floor (the Caldera) which is over 6 miles in diameter and filled 2500 feet thick with ice covering the crater floor.
►"That FLOOR has dropped 25 meters (80 Feet) this week.
►"Scientists are now gravely concerned that the crater floor will soon collapse into a miles deep underground cavern filled with boiling white hot magma.
►"There's 1 trillion gallons of water in the ice in Bardabunga crater.
►"When that falls into a lake of magma it will instantly flash into steam expanding 600 times in volume.
►"The magma, suddenly no longer contained by the crater floor and 1 trillion gallons of water will act like a shaken soft drink can when the top is popped.

Sinking Iceland volcano crater raises flood worries


REYKJAVIK (Reuters) - Iceland's Bardarbunga volcano registered one of its most powerful earth tremors yet on Wednesday while the sinking of its caldera raised concerns of an eruption and flooding, authorities said.

The caldera, the cauldron-like crater at the top of a volcano, had sunk by up to around 20 meters since last week as magma channeled through underground passages moves away from the volcano, Magnus Tumi Gudmundsson, geophysics professor at the University of Iceland, told public service broadcaster RUV.
The caldera covers about 80 square km and is covered by an ice cap that is 700 to 800 meters thick.
A cloud of abrasive ash from the Eyjafjallajokull volcano, in a different region of Iceland, closed much of Europe's air space for six days in 2010, stranding tens of thousands of passengers, after an eruption under the ice cap.
"We take this increased subsidence in the caldera of Bardarbunga volcano very seriously, due to a possible large eruption and glacial flood," said Vidir Reynisson, Department Manager at Iceland's Civil Protection Department.
The ash warning level for aviation remained at orange, the second-highest level on a five-color scale, after several brief hikes to the top red in recent weeks.
Lava continued to pour from fissures in the ground, but there was still none of the ash that could prove troublesome for airline traffic. The 5.5 magnitude earthquake happened at 0528 GMT (01:28 a.m. EDT) near the volcano, Iceland's Meteorological Office said.
"This is one of strongest earthquakes since Aug. 16 (when tremors began). There is a lot of activity in the area and approximately 70 earthquakes have been measured in the night," said IMO geologist Sigurlaug Hjaltadottir.
Lava from cracks around Bardarbunga has so far entered the surface on ice-free land, whereas an eruption under an ice cap may be explosive and produce an ash cloud that could disrupt aviation, as well as flooding due to melting of the ice.
