Grimsvötn volcano (Iceland): accelerating rates of subsidence increase likelihood of glacial flood and perhaps an eruption
The ice sheet on top of the volcano continues to subside and does so at accelerating rate: Compared to a week ago, the surface has sunk by 4 meters, but more than half of that occurred during the past 48 hours, and it is not clear how much is yet to come. In any case, it suggests that more and more melt water normally trapped above the summit area is now flowing away to different locations further at the side of the ice shield. This makes a glacial flood very likely in the next days - once enough water has accumulated beneath the rims of the glacier, it can lift it and surge out, and/or melt and erode itself a channel through its bottom, to exit in a massive, violent glacial flood known as jökulhlaup (literally "glacial run"). According to geologist Björn Oddsson from Civil Defense in an article on grapevine.is , "melt water is accumulating under an ice cave that lies at the top. There's a GPS measuring device over the ice cave which indicates the situation with t
