Askja volcano (central Iceland): caldera lake ice-free, unusually high water temperatures
Wednesday Apr 04, 2012 22:11 PM | BY: C!H!F
Some news has appeared about a sudden warming of the Askja volcano caldera lake. It seems that a melt of ice in the caldera lake started in the beginning of March and by the end of March, the lake was completely ice free.
This is highly unusual and it is not known to have happened before. Such increase in hydrothermal activity is probably caused by a heat source at the bottom of the lake, although so far, there are no other changes visible around Lake Askja. Hydrothermal areas around Askja are active recent reports confirm.
Whether the raised temperature of Askja lake is a precursor to a new eruption in the foreseeable future is speculation at this point.
