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.
The 47th Nordic Seismology Seminar will be held in Reykjavík, 11-13 October 2016.
The meeting will commence on Tuesday in the early afternoon and last until Thursday evening.
Those who are interested in attending, are encouraged to apply for participation.
The eruption in Holuhraun in central Iceland in 2014 - 2015 was the largest seen in Iceland since 1783. The ice-filled caldera of Bárðarbunga central volcano collapsed during the eruption as 1.9 km³ of magma flowed laterally from a magma reservoir under the volcano. Eruptions of this type are not common. This caldera collapse is the first where it has been possible to carry out detailed observations during the events. Unique data was obtained that threw new light on the mechanism of caldera collapses and their interaction with the associated eruptions. A large team of scientists has analyzed the data from Bárðarbunga and published the results in the journal Science.Read more
Seismic activity in the Katla caldera has increased in recent weeks, but this is not unusual during the summertime. The activity is associated with drainage of meltwater from several known ice-cauldrons due to hydrothermal activity. Four small floods have been detected and a smell of sulfur has been reported from several locations; these events combined with higher conductivity indicate presence of geothermal water. Measurements around Katla are not detecting signs of increased ground deformation or seismic tremor, both of which would be indicators of magma movement. Experts at IMO assess that an eruption is not imminent, however, a hazardous flood cannot be ruled out.Read more
