Influences on the Bardarbunga Caldera

Bardarbunga GPS Data

As subsidence continues, I have to wonder what are the outside influences on the Bardarbunga caldera. How much additional downward pressure will come from ice and water sliding/running down into the new pit. I am not sure of the GPS unit’s proximity to the glacier. So I don’t know if the subsidence is close enough to allow ice or water to fill the giant pit. If it is close enough and water and ice is flowing inward, I would think the addition of the weight would just exacerbate the problem. Has something been set in motion here that cannot stop until the caldera fails? […]
