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
Travellers on “Laugavegur” in South Iceland, the popular highland trek from Landmannalaugar to Þórsmörk, are warned that water levels have risen in river Bláfjallakvísl, north of Mýrdalsjökull.
Hikers are advised not to attempt to cross the river, as waist-high water levels have been reported. The water discharge is expected to continue increasing over the week-end due to warm weather.Read more
Of the thirty active volcanic systems in Iceland, Hekla is one of the most active and potentially dangerous. In this summary we outline the types of hazards that might occur during the next Hekla eruption, and how the Icelandic Meteorological Office is monitoring the region.Read more
The Civil Protection Scientific Advisory Board met June 23rd, in order to review new data on the volcano Bárðarbunga.
The most probable explanation for ground deformation and earthquake activity in the area, is inflow of magma at about 10 to 15 km of depth below Bárðarbunga. There are no indications of magma collecting at shallower depths. This process is common in the aftermath of volcanic eruptions.
Probably meltwater will start collecting under the cauldrons along the caldera rim or within the caldera itself. Therefore it is imperative to monitor the evolution of the cauldrons, the seismic activity, ground deformation, geothermal activity and gas emissions in Bárðarbunga.Read more
