Bárðarbunga keeps going down in fits and starts: just one powerful quake alone is believed to have caused a drop of nearly half a meter. Again, this is unexplored territory; the last time a major subsidence event occurred in Iceland, the forming of Askjas caldera in association with her catastrophic 1875 eruption, was little studied until after the event concluded. The plume from the eruption on Holuhraun is today aiming at the small town of Kópaskeri... but due to a shortage of gas meters, theres none in the area and people dont know how high the concentrations are getting or at what time. The Mist has cloaked the town, and apparently containing particulate matter thats precipitating out on cars, but people dont know whether levels of gas and particulate are such that they should be shutting themselves in their homes or not. Some people felt sick from it; others didnt. We covered the other day that the volcano is creating its own windstorms. But rain? The answer appears to be yes; the steam exhausted directly from the lava, plus the steam from the boiling river water, appears to be condensing into rainstorms in the area. Concerns have been expressed that the water could be poisonous, but there is no evidence to back this at this point in time. Visible activity on Holuhraun has again dropped, but influx and spreading keeps continuing. This is not a good thing. According to researchers, if outflux at Holuhraun stops without a corresponding stop in input and spreading, its just going to open up somewhere else, whether that be under Dyngjujökull, in the Askja system, or in Bárðarbunga. As Holuhraun is pretty much the best spot the eruption could be positioned, we do not want this to happen. dailykos/story/2014/09/16/1330073/-B-r-arbunga-Not-Parrying-Any-Questions-An-Interview-With-orbj-rg-g-stsd-ttir#
