Dyngjujökull station - 10.9.2016

In June 2016 a weather station was established on the upper reaches of Dyngjujökull, about 10 km north of the Grimsvötn caldera, at 1689 m above sea level.

A seismometer has been in operation by the IMO at the site since the autumn of 2014 and the main purpose of the new weather station is to monitor conditions at this important location in the network, amongst the volcanoes of Vatnajökull.

Minor jökulhlaup in Skaftá - 8.9.2016

8.9.2016: The level of Skaftá river has risen significantly. This suggests that a glacial outburst flood is in progress.

Hydrogen sulphide is released from the floodwater as it drains from the ice-cap and H2S is particularly potent at the ice margin (poisonous levels). Travellers must stay away from the edges of Skaftárjökull and Tungnaárjökull while the flood occurs.

Crevasses will develop rapidly around the ice cauldron, so travellers on Vatnajökull should stay away from the region.

Katla and Mýrdalsjökull - 31.8.2016

Since mid-June, there has been heightened earthquake activity in the Katla caldera. Summertime increases in caldera seismicity are an almost annual occurrence at Katla, often associated with the drainage of geothermal meltwater in the form of minor floods in glacial rivers from Mýrdalsjökull

These are not necessarily precursors to an imminent volcanic eruption. Similar unrest has taken place at Katla several times since the 1950s without culminating in an explosive eruption.

Travellers are urged to not spend time close to Múlakvísl, especially the upper reaches of the river, as measurements near to the source show unhealthy levels of hydrogen sulphide, signifying high concentrations of geothermal fluids.
