It was announced today (19-January-2014) that glacier flood has started in Skaftá glacier river (or connected rivers) from Skjaftár cauldrons in Vatnajökull glacier. Currently the water is discharging from Skaftár cauldrons at the rate of 370 m3/s according to Icelandic Meteorological Office. So far no changes have taken place in harmonic tremors close to Hamarinn volcano where the Skaftár cauldrons lie within Vatnajökull glacier.
Smell of hydrogen sulphide has been detected by people living close the rivers that the glacier flood is discharging into. There is a considerable risk of poisoning if people get to close the rivers that hold the flood water. It is currently believed that it is the western Skaftár cauldron that is now emptying, that one did empty it self back the in the year 2012. That is however not going to be confirmed until the area can be checked by flying over it and see what is taking place at this location. That might take few days since it is dependent on weather when it is possible to do such flight.
