A total of 370 earthquakes were detected during the week. As in previous weeks, the highest number of earthquakes occurred in the dyke under Dyngjujökull glacier. The biggest earthquake of the week was only of magnitude 2, located by the Bárðarbunga caldera. The jökulhlaup from Grímsvötn peaked in the middle of the week and tremor related to the water flow was observed at stations in the area. More

The snowpack has been strengthening and no activity observed in the last days.
The snowpack have been strengthening but it could get weaker when it gets warmer on Saturday.
Risk of wet loose avalanches in steep slopes, but the snow is subsiding.
The avalanche forecast is written for large areas and doesn't necessarily represent avalanche danger in urban areas.
In early April 2015 the natural hazards banner was removed from the header of IMO‘s website. The short-cuts can now be found in an overview article which contains all the links on these issues provided by IMO since August 2014.
Gas emission from the lava field is still being monitored by continuous measurements around Holuhraun. The gas dispersion model is still operational but text forecasts are no longer made.
Seismic monitoring is as thorough as before and on any significant increase, the natural hazards banner will be presented in the header of all IMO‘s web-pages again.
A minor glacial outburst flood (jökulhlaup) is occurring in the river Gígjukvísl on Skeiðarársandur. The flood, which originates from subglacial lake Grímsvötn, became apparent on 6 May when the level of Gígjukvísl began to rise steadily.
Potentially hazardous levels of hydrogen sulphide gas could be present at the location where floodwater bursts from Skeiðarárjökull. In the immediate vicinity of the outlet, gas concentrations could be high enough to cause respiratory problems and even damage to eyesight. For travellers on Skeiðarársandur, the ongoing flood poses no hazards.Read more
IMO has changed the Aviation Color Code for Bárðarbunga volcano from yellow to GREEN, as from 24 April 2015.
This decision has been taken in light of recent seismic and geodetic data from around the volcano, in addition to other measurements such as satellite-based thermal observations and radar-profiling flights.
Bárðarbunga continues to be monitored closely and any significant change in the volcano's state will be reported immediately.Read more
The year 2014 was very warm, preciptiation was abundant and the sunshine duration during most of the summer was considerably below average.
In spite of the high temperatures the weather was changeable and often dull.
The first months of the year were especially wet in the North and East and the weather was difficult. In the west it was very dry at the same time with favourable weather conditions.
The summer was warm and considered fine in the North and East but in the south it was very wet and dull.
The autumn was fine, November extraordinarily warm, but the year ended with an unruly and rather cold December.Read more
Friday 20 March 2015, an almost total solar eclipse will be seen from Iceland, such as has not been seen for 61 years. And it so happens, that this time, it will occur on equinox.
Clouds may impede the view. Check IMO's cloud cover forecasts, where white means clear skies, and adjust the scale underneath the map for correct timing (roughly betwen 08:30 and 10:40). The tabs above the map will show more selective forecasts for low, high or middle clouds.
People are strongly advised against looking at the sun without proper precaution. Even a glimpse towards the sun might cause irretrievable damage to the eyes.
The volcanic eruption in Holuhraun has come to an END. For the first time, no glow was seen in a flight 27 Feb.
Volcanic gas can still get dispersed all over the country; emission has not ended.
The lava field is now 85 km². The average thickness is at least 10 - 14 m (max 40 m) and the volume is about 1.4 km³.
The maximum subsidence of the caldera is at least 61 m and the rate was only 5 cm/day last week, compared to tens of centimetres earlier. The volume of the subsidence is 1.7 - 1.8 km³.
Conditions on the eruptive site are still dangerous. Gas emissions at the eruption site and from the lava field are still life threatening.
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
