Easterly winds, 3-8 m/s and partly cloudy, but 8-13 m/s and intermittent rain or drizzle in the southeast parts. Scattered fogbanks along the coast, but the odd afternoon shower inland. Temperatures 10 to 20 degrees C, coolest by the seafreont.

Around 320 earthquakes were detected by the permanent seismic network of the Icelandic Meteorological Office during the week, there of were three earthquakes over magnitude 3.0. Two of the earthquakes occurred on the 21. August, one of magnitude 3.0 some 4.5 km southwest of Geirfugladrangur on Reykjanes ridge and the other of magnitude 3,4 in Bárðarbunga. The largest earthquake of the week occurred in the northern rim of the Katla caldera and was of magnitude 3.5. Over the weekend was some increased seismicity by Grímsfjall in Vatnajökull icecap and also just east of Herðubreiðartögl in the highlands. More

According to local reports, the level of the Bláfjallakvísl glacial river is unusually high. Bláfjallakvísl originates from the northern side of Mýrdalsjökull and people are advised to show caution when crossing the river.
A small glacial flood has started from Grímsvötn volcanic system which runs into Gígjukvísl river, south of Vatnajökull. Only a small amount of water was in Grímsvötn so odds are that the flood will be not be a large one. It's possible that smell of sulfur will be detected in the area but chances of there being any danger due to this flood are extremely low.

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
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
