Over 300 earthquakes were located with the SIL system during the week. An earthquake swarm occurred by Húsmúli with nearly 300 earthquakes and about 150 earthquakes were located in Öxarfjörður north of the country. All earthquakes were smaller than magnitude 3. More

In most places crust layer with thin layer of new snow in lee area that is unstable. Reported skiers triggered avalanches on lee slops. Next avalanche bulletin on Saturday.

20mm precip on Tuesd. in SW-wind. Thaw in the mountain with precip on Thursd. Snowshowers in strong SW-wind Friday.
Windslab after NE-winds last weekend is somewhat unstable and ski triggered avalanche fell on Sunday.
Crust with unstable snow in W aspect but generally stable else. Forecast predicts thaw up high with some precip.
The avalanche forecast is written for large areas and doesn't necessarily represent avalanche danger in urban areas.
A small jökulhlaup, glacier outburst flood, occurred in the river Gígjukvísl in March. The event originated from the subglacial lake Grímsvötn. No threat was expected from the flood, which did not exceed high river discharge at summer.
The river Skeiðará changed its course in 2009 and now runs due west along the margin of Skeiðarárjökull outlet glacier and contributes to the river Gígjukvísl. Further information on the causes and consequences of this shift is given below.
Real-time information about snowpack conditions, recent avalanches and avalanche danger is part of IMO's monitoring. Information about avalanches reported during the last ten days is now presented on the web in the form of an interactive map and a table. People are encouraged to report avalanches that they come across using a specific internet form.
Iceland will now have unlimited access to satellite earth observation data that relates to many aspects of atmospheric, land and ocean monitoring. This will improve Iceland‘s forecasting cabilities, bringing significant benefits for key industries such as fisheries, agriculture and tourism, enhancing public safety and supporting other important areas such as road construction, research and education.
The weather in Iceland in 2013 was mainly favorable, however, the spring was harsh in the North and East and the summer was on the dull side in the South and West, with precipitation and cloudiness above average. This was the dullest summer of the new century in this area of the country.Read more
The glacial outburst flood is thought to have peaked 20 January and is now subsiding. Photographs show the flood at its peak. Floods in Skaftá are sourced from two ice cauldrons, formed due to persistent geothermal activity beneath Vatnajökull. On average, the cauldrons drain every two years, producing floods of up to 1,500 cubic metres per second. When the interval between floods is short, the flood tends to be smaller.
19.01.2014 Flood conditions are expected in Skaftá over the next two to three days. Some flooding of unpaved roads close to Skaftá is possible. Hydrogen sulphide is released from the floodwater as it drains from the Vatnajökull ice-cap. The gas is particularly potent at the ice margin, where concentrations will reach poisonous levels. Travellers must stay away from the edges of Skaftárjökull, Tungnaárjökull and Síðujökull while the flood occurs. Crevasses will develop rapidly around the ice cauldron, so travellers on Vatnajökull should stay away from the region, including the lower part of Skaftárjökull and Tungnárjökull, where floodwater could burst through the surface.Read more
Weather forecasts and the current weather condition can be checked through a weather app provided by IMO. Location is detected if GPS on; alerts issued by the Met Office appear automatically during the day and a personal weather watch can be arranged to send notifications when certain criteria are met. An interactive weather map shows weather observations at any station in the country.Read more
